The computer does not show the memory card. The PC does not see the memory card: SD, miniSD, microSD. Search for reasons. Sector corruption on the memory card

MicroSD recovery is a very popular topic in our time, because flash drives break very often, and you don’t want to lose information from them.

Therefore, many people are looking on the Internet for information on the easiest way to get information from a medium that does not work.

Moreover, the problems can be very different - someone's flash drive simply cannot be restored, someone has errors, and so on.

And the answer to the above question is very simple - there is a special program for recovering MicroSD, and far from one.

The user only needs to use the most suitable of them.

MicroSD recovery software

CardRecovery

This program does an excellent job of recovering photos, video and audio content from storage media.

Unfortunately, it does not restore regular files, and therefore it is intended only for those flash drives that are used in mobile phones, cameras and players.

How to use CardRecovery:

1. Download the program from this link. Run it, read the greeting and click Next.
2. We select the flash drive in the Drive letter section, the device type in the “Camera Brand and File type” section (check the boxes next to the types of files that will be restored there) and the folder where the recovered files will be saved in the Destination Folder section. Click Next.
3. We are waiting for the end of the recovery process. Click Next.
4. We see a list of recovered files. Check the boxes next to the ones you want to keep. Click Next for the last time. The process is over.

PC Inspector Smart Recovery

This is already a much more functional program that recovers almost all types of files available today.

It works for both fixed hard drives and removable media. To use it, you must do the following:

1. Download the program from this link. Open it.
2. In the start window, select the "Restore logical files" item. You may need to click on the tab with the green up arrow on the left.
3. Next, you need to select the desired drive on one of the tabs (it can also be among logical drives). Click on the checkbox on the right.

Hint: You can find out the letter and name of the flash drive in Windows in “My Computer” (“Computer”, “This Computer”, depending on the OS).

1. Select a start and end sector. You need to do this so that the scan size matches the size of the media. Click on the checkbox on the left.
2. Next we will see a list of all files. Green indicates those that can be restored, and yellow indicates those that do not require restoration. After that, you need to click on the floppy disk icon on the left.

R-studio

On the official website they write that today it is the most “comprehensive” file recovery software.

Users do not resist this conclusion. To recover data using R-Studio, do the following:

1. Download the program (here is the link) and run it.
2. In the Drivers section, click on the media from which the data will be restored. The Properties section will display its properties.
3. Further, the folders will be displayed in the Folders section, and the files in this folder will be displayed in the Contents section. To restore them, you need to click on the Recover button on top panel program windows.

Easy Recovery

Many experts say that this is indeed good program to restore files. There is only one way to check this:

1. Download free version programs from this link and run it.
2. In the start window, click "Continue". In the next select "Memory cards".
3. Click "Continue" again. Select "Data Recovery" and check the box next to the file system of this media at the bottom.

Sometimes the recovery of a MicroSD flash drive using the above programs does not go as smoothly as you would like - some problems may arise.

Consider the most common of them.

Problems with microSD recovery

MicroSD not detected

It happens that you need to restore the MicroSD card, but the computer - tritely - does not see it.

Interestingly, this usually happens completely unexpectedly and for no apparent reason: the user once again inserts the card, and suddenly the computer stops seeing it (it used to insert it, and everything was fine).

In this case, there are three options:

1. 1. The letter of the disk name matches the letter of the already connected disk. Indeed, it is possible that some kind of storage medium is already connected to the computer, and for some reason the flash drive is indicated by the same letter when connected. In this case, you need to open the standard Disk Management utility (Win + R and enter "diskmgmt.msc"), select the flash drive there, right-click on it and select "Change drive letter or drive path." After that, it remains to specify some other letter of the Latin alphabet and save the changes.

1. 1. Lack of drivers. In some cases, both the old tested and the new computer with a freshly installed operating system may not have drivers for some media. There is only one way out - download and install them. The best thing to do is to search on the official website. You can use the DriverPack Solution program. You can download it from this link. It independently determines which devices are connected to the computer and whether there are driver updates for them. It is convenient that the program itself will determine whether the drivers for the flash drive are installed. If this is not the case, they will be installed in bulk, along with everyone else. To do this, the user just needs to click on the "Drivers" tab on the left and click on the "Install automatically" button.

1. You can also try connecting the memory card to another device. This will give a chance to still read the necessary files and use the recovery program. For example, you can insert a MicroSD into your phone and restore not the card itself, but the entire phone as a carrier.

Read other GeekNose materials about data recovery from disks:

Another common problem is that the computer sees the flash drive, but does not see the files themselves on the flash drive.

The computer "does not see" microSD files

This means that the flash drive itself is detected by the computer, but some files (or even all) are not on it.

The user may immediately think that the problem is in the card itself and it needs to be restored. But things can be much simpler.

The solution to such a problem is to scan the computer for viruses, in particular, Trojans, and remove them.

Indeed, the "trojan" can make files hidden. Therefore, feel free to turn on and use your antivirus before lamenting about lost data.

It is worth saying that in some cases, the MicroSD recovery process may differ depending on the device manufacturer.

MicroSD recovery from different manufacturers

Recovery MicroSD Transcend

For MicroSD cards Transcend has its own file recovery software. It's called RecoveRx.

This program takes into account the individual characteristics of the cards of this manufacturer and is able to perform its functions much better than all of the above programs.

In addition to recovery, RecoveRx can format the card and put a password on it.

To perform a restore, you must do the following:

1. Download and run the program (here is the link). Select Recover from the top menu. In the program window, select Transcend (it may differ depending on the name of the card, by default it is as shown here).
2. Select file types.
3. Wait for the process to finish and see the list of files available for saving. Save the ones you want using the drop-down menu (the one that appears after right-clicking on a file).

Recovery MicroSD Kingston

The problem with flash drives from this manufacturer is that they mainly use Phison controllers.

And this means that the user will have to resort to low-level recovery.

Other methods may simply not work. In short, the process is as follows:

1. 1. Determine the Vendor ID and Product ID parameters so that you can then use them to find the desired utility. This can be done using the USBDeview program (link). Open the program and find desired card in the list. Click on it with the right mouse button and select the item "Html-report: selected elements". We scroll the window that appears until we see the Vendor ID and Product ID.

1. We go to the site flashboot.ru/iflash/ and enter the necessary parameters in the appropriate fields. As a result, we will see a list of all cases where there were problems with this model. And on the right, in the UTILS section, there will be programs for low-level recovery of this model. The user needs to try them all - usually you can find more on the official websites detailed instructions by use.

MicroSD Kingmax Recovery

Kingmax also has its own software. There are two programs - one for U-Drive and PD-07 series drives, and the second for Super Stick.

You can download both programs.

Their use is extremely simple - you need to insert a USB flash drive, run the program and click on the desired drive.

Sandisk microSD recovery

After that, the flash drive will work like a new one. The use of the programs is very simple.

In Silicon Power Formatter there is generally only one small window with two buttons (you need to click Format there), and in SDFormatter there are more options, but it will still be enough to click on the Format button.

Smartbuy microSD recovery

Working with flash drives from this manufacturer is characterized by one interesting point - if the flash drive does not work, you can simply wait, up to several years, and after that it will work again.

If you don’t want to wait, you need to try all the recovery programs that you can find.

This application looks like a regular folder.

After selecting the media, you need to click on the Recover button at the top, wait for the process to end and see a list of files that can be recovered.

Qumo microSD recovery

MicroSDs from Qumo are notorious for the fact that they just suddenly "die". Once they stop working, and after that it will be very problematic to see at least some signs of life in them.

Some users advise using the aforementioned R-Studio and CardRecovery programs. But not in all cases they will be effective.

There are special companies that are engaged in the restoration of "dead" flash drives using hardware methods, but such services are not cheap, and it is usually cheaper to purchase a new drive.

Recovery A-Data MicroSD

In this case, too, most programs do not help. Paragon Partition Manager Free works best with A-Data flash drives.

First, in this program, you need to format (Format Partition button in the main menu), and then create a new empty partition (Create new partition).

Oltramax microSD recovery

In this case, full formatting with the SD Card Formatter also helps a lot. In some cases, it is possible to restore the drive's performance using ALCOR MP.

Full instructions for its use can be read.

Recovery of damaged microSD

In some cases, when using the drive, the message “Damaged memory card” or something similar may appear on the screen.

The following programs help here:

• Smart Data Recovery - you need to select the media and click the Find button, after which it will search for all files that can somehow be recovered;

Rice. No. 14. List of files available for recovery in Recuva

• BadCopyPro - click on the Memory card on the left, then Next, Next again, wait for the process to end and see a list of the necessary files.

The same operations can be performed on an Android device. The following applications help here:

Prevention

It is better to use the flash drive correctly first, so that later there are no problems with its malfunction. Here are some tips to help avoid microSD breakdowns:

1. Do everything possible to prevent the drive from being dropped, bumped, bent, subjected to extreme temperature changes, or other influences that could damage it.
2. Avoid ionizing radiation (such is, for example, in x-ray machines).
3. Do not touch the contacts with your fingers and generally try to keep them always covered with a special cover.
4. Defragment the card from time to time and generally use it regularly - MicroSDs don't like to just lie on a shelf.
5. Try to make backups from time to time so that in case of a breakdown you don't lose all your data. To do this, you can use the "cloud" storage.
6. Do not fill the entire volume of the drive, let there always be some free space.
7. If the card is in some device, try to remove it less often.

See our other materials on formatting hard drives and flash drives:

A flash card is the most functional and popular storage medium in modern times. CDs have their own positive sides, but the amount of memory, ease of use and other factors on the side of the flash drive.

You can also connect a USB flash drive to an Android smartphone, and even the cost today is on the side of the memory card, because cheap options will cost only a couple of times more than DVD-RW.

Only it's much easier to disable or lose a memory card

It happens that a person removes this storage medium from his own smartphone or digital camera, but the computer does not open it. This is due to virus infection, software failures, and breakdown of the device itself. In such a situation, you need to restore the micro flash drive by changing the partition letter or in other ways.

VARIETY OF DEVICES OF THIS TYPE

Before you restore a memory card, you should familiarize yourself with the varieties of this small but useful detail. People are not very versed in this issue, which also brings problems. Today, three types of SD devices are produced: micro, mini, SD.

It would seem, why divide one species into three more additional ones. But this is a logical decision, because SD is used in various technologies: camcorders, video recorders, smartphones, mp3 players, etc. Gadgets differ in size and requirements for the power and memory of the device. Therefore, there are three subspecies, which are worth familiarizing yourself with in more detail:

• microSD. The micro SD memory card, due to its format and storage capacity, is commonly used in smartphones, tablets and media players.

A small device allows you to increase the memory of the gadget several times

• MiniSD is already slightly larger than micro. They are used on players and phones that are already 5-10 years old.

Today gave way to the previous option

• SD. This is the largest type that is used in photo and video equipment, in particular, in car recorders.

This option is distinguished by a large amount of memory and good speed.

Interestingly, the first option, if necessary, can be turned into a third one using an adapter. A micro card is inserted into this adapter, and then the design is inserted into devices that work with SD.

But this combination will not be able to fully replace the large version, because the speed of work will be too low

IMPORTANT NUANCES IN USING THE MEMORY CARD

1. In addition to the amount of memory, speed is also indicated on the surface of the product (to be precise, the class). So, if this indicator is 10 for a flash drive, then you can transfer data to the device at a speed of 10 MB per second. It is worth considering which class is necessary for the normal operation of the gadget.
2. A memory card for a phone can be used as an SD card using an adapter. But, as already mentioned, it is not advised to do this due to the mismatch of the class of parts.
3. The USB card reader for flash drives must be selected based on compatibility. When a gadget that opens SDHC is used, it will be able to work with SD 1 or 1.1, but it will not work to read SDXC.

Before buying devices for reading, you need to consider this characteristic.

Notebooks that are 7 years old or older may be equipped with standard card readers, but they cannot open SDHC. A card reader that connects via USB will help solve the problem. It costs a couple of hundred rubles. You can also use an otg cable (it will help you connect a micro sd card reader or a regular USB flash drive even to a smartphone).

SAME NAME OF SECTIONS

Let's return to the problem of device unreadability. A flash drive will not appear in the "My Computer" menu if it is given the name D, and the operating system section works with the same name.

fig.1. Unlocking a USB flash drive in such a situation is not difficult, for this the Disk Management menu opens (the combination of the Win and R keys and the command diskmgmt.msc)

A menu will appear on the screen, which displays the folder of each disk, and devices connected via the USB input. When a memory card appears in this menu, you need to reanimate the flash drive in one of the following ways:

• Put a unique letter in the name, under which there are no sections yet.

fig.2. This is done by pressing RMB and then selecting the operation to change the letter

• Format the SD card using regular Windows tools or using special utilities. But it is worth considering that all files from the storage medium will disappear.

PROBLEM WITH DRIVERS

If you can connect the USB flash drive to the tablet, but not to the computer, then the necessary driver may not be available.

It happens that employees of hardware stores forget or do not have the desire to install necessary components and sell computers like that. Included with the equipment should be disks with drivers, the installation of which will not take much time. If the computer is not new, or the disk with the "firewood" is lost, then the almighty Internet will help. In such a situation, the recovery of a micro sd flash drive will be limited only to the search and installation of components.

Special utilities are available on the Internet to analyze the operating system and find the necessary drivers, they will greatly simplify the task.

CONNECT WITH OTHER GADGETS

If the flash drive connects to the phone without problems, but it is not visible on the PC, then why not use this smartphone as a conductor and connect it directly to the computer (you can use the otg usb cable)

Most users rarely pull out a memory card to work with files through a computer.

The only concern is whether special software is needed for this purpose. In new versions of the operating system, you do not need to install anything else, Windows 7 and 8 automatically install device drivers. If desired, you can also use the program from the manufacturer (for example, NokiaPCSuite).

As you can see, restoring a microsd memory card is a simple matter, sometimes you need to install drivers, change the partition letter, or use third-party devices.

AT recent times Increasingly, users have problems regarding the operation of SD cards on various devices. The card is inserted into the appropriate port, but the computer is not able to see it, and also it is not shown in the settings. This is an extremely common and rather serious problem, which, as practice shows, is almost always easily solved. In this case, it is worth familiarizing yourself with the causes of the malfunction and how to solve them.

Most users often do not distinguish between types of memory cards. It is worth knowing that they are of the following varieties:

Important nuances in using a memory card

Before buying and starting to use these cards, you should familiarize yourself with the important nuances of their use.

• in addition to the amount of memory, they indicate speed. You need to know which card speed class is suitable for a particular device;
• using special adapters, microSD can turn into regular SD cards. True, it is not recommended to do this often, since the speed of information exchange drops;
• Older generation laptops have built-in card readers that can't handle newer models like SDHC, but there's a simple solution to this problem - get a card reader that connects to standard USB ports - it's more like a standard flash drive and is quite cheap.

Why does the computer not see the memory card?

Since the drives described above are extremely fragile, they often become unusable due to defects or improper shutdown.

Reference! Sometimes it happens that after a short use of the card, it is simply not readable or not detected by devices, so it is not recommended to rely on the long-term operation of such drives.

There are a number of common reasons why a laptop or PC cannot display an SD card. We are talking about:

If the media is no longer detected by a phone, camera, or other device, it needs to be removed and installed on a PC in order to diagnose, identify, and fix the problem.

What actions to take if the device refuses to recognize the memory card?

To eliminate the problem, a search for the cause is required, which, in turn, can be very different. You should familiarize yourself with step by step instructions, which will tell you what actions to take when the computer is not able to detect SD or microSD cards.

How to correctly check the malfunction of the memory card and card reader

The first step is to identify media problems. To do this, you need to connect it to any other working device. Also, if there is a second card of an identical model, it can be determined whether it is capable of being recognized by a computer. If everything is fine, then there are no problems with the card reader and the reason is probably in the card. Often they become faulty after they are illiterately removed during working hours or wear out on their own.

In such a situation, the only solution is to try to restore the functionality of the product. A specialized utility called HDD Low Level Format Tool helps with this. For its proper use you will need:

Step 1. Download and install software on your computer from an official source.

Step 2 After starting, select a memory card and proceed to the next step.

Step 3 A new menu will appear, in it you need to click on "LOW-LEVEL FORMAT".

Step 4. A warning menu will appear stating that all information will be formatted. We agree to click on the format button.

No less popular and effective is the SDFormatter utility, which is also able to cope with the task of formatting. To use it you will need:

Step 1. Install and run SDFormatter software.

Step 2 During startup, the utility will automatically detect the connected flash cards displayed in the main window. Press "Option" to set formatting options.

Step 3 In this case, "Qick" means formatting in quick mode, "Full" will erase all data, and "Full (Overwrite)" will additionally overwrite.

Step 4 After returning to the main menu, you need to click "Format", after which the utility will format the memory card. The file options will automatically be set to FAT32.

Reference! Sometimes the card reader itself refuses to display the memory card. The way out of this situation will be to contact a specialized company, the masters of which will perform the repair. Do you need a card urgently? There is a temporary solution: we are talking about a portable card reader available for connection to a laptop via a USB port.

How to check for crashes in Windows OS

In more rare cases, the PC refuses to detect and recognize the memory card due to operating system malfunctions, for example, Windows may incorrectly assign the letter of the attached media. The following steps are taken to correct this conflict:

Step 1. Open the "Control Panel" through the "Start" menu.

Step 2 Select the "System and Security" section.

Step 3 Then go to "Administration".

Step 5 By clicking on the last item, the "Disk Management" tab will appear on the left.

Step 6 You must select the required card in the list of installed drives and right-click to bring up a new menu. Next, click "Change drive letter ...".

Step 7 A letter is selected that has not yet been used in the system, after which the settings are saved.

Driver update

If nothing happened after a kind of reboot of the adapter, there is another way to fix the problem - to update or reinstall the card reader drivers. In this case, you need to visit the manufacturer's resource and see if the latest version of the driver has appeared. If it really is, you can download and install it. Before that, it is better to remove obsolete drivers in .

Virus check specifics

Even the most modern device without fail is recommended to be supplemented with anti-virus protection. To fix the problem, you will need to scan the memory card and clean the malicious files.

Step 1. You need to go to "This PC" through the desktop shortcut or through the "Start" menu.

Step 2 Right-click on the memory card icon, thereby calling up a new menu, and then select the "Scan ..." option.

We right-click on the memory card icon, select the option "Scan ..."

On a note! In the menu, the item will correspond to the installed antivirus program on your device.

Step 2 In the "Control Panel" set the "View" mode to "Large Icons". Select Folder Options.

Step 3 Open the "View" section.

Thus, there are a sufficient number of reasons why a PC may not see SD cards. To accurately resolve the problem and use the media again, it is recommended that you follow all the above steps.

Video - The card reader does not see the SD card, what should I do?

What to do if the phone does not see the memory card? Since I often get asked this and similar questions, I answered them all at once in this article. It will be useful for owners of cameras, Samsung, Lenovo phones, laptops - in general, all those devices that support a memory card and refuse to read data on the card.

First, some technical details describing the problem. Let's say, as a result of some manipulations, a mobile device (phone, tablet, smartphone) has ceased to identify a memory card (sd card) even through a card reader. All data is written to the internal memory of the phone, bypassing the actual memory card. This is inconvenient as the sd card is not being used while the mobile device's memory is rapidly filling up. Productivity decreases accordingly.

So, the problem is described in detail, let's move on to diagnosing a phone, smartphone, tablet. Consider the most common reasons why phones do not see a memory card (flash drive) and how to fix this defect on your own using a card reader.

The phone does not see the sd card due to an incorrect file system format or a corrupted file table

Cause of the problem. 1) The file table on the sd card was damaged, the markup fell off. 2) You formatted the memory card yourself, as a result of which the phone stopped seeing the flash drive. 3) The file system of the sd card is unknown (used in another operating system)

How to fix. 1. Find out the size of your flash drive. If the microSD capacity is more than 32 Gb, most likely it is formatted in exFAT. Not all android versions support this file system.

2. A quick way to fix the problem is to reboot the phone in recovery mode and select the Wipe cache partition option in the Android service menu. This command will clean the contents of the sd card and format the media in the FAT32 file system - it is best suited for storing files on the phone.

Note. We would not advise inexperienced users to perform this procedure: if you mistakenly format the wrong partition, you will lose all data on the phone, including files in the internal memory.

3. A safer (and more convenient) method to format an SD card is through a computer. You will need a card reader and SD Formatter software. It will help you format your flash drive properly.

4. You can try low-level formatting - however, not all manufacturers offer their own software for this (check the memory card website).

The memory card of the phone (tablet) is out of order

Cause of the problem. As a result of mechanical / thermal damage incompatible with life, the phone stopped seeing the memory card or the sd card stopped working. As an option, the phone stopped detecting the flash drive, on other devices the card is also unreadable.

What to do. Alas, nothing can be done with a damaged sd card. All you have to do is purchase a new SD card that is compatible in size and specifications with your smartphone or tablet. The most unpleasant moment is all the data that was stored on the memory card android phone or iOS, disappear completely. You can no longer restore them - neither by connecting a phone with a USB flash drive, nor through a card reader.

If the flash drive still has a warranty and it looks like new (no visible damage), try returning it to the store. If you're lucky, you'll get a brand new replacement card.

Check for bad blocks (bad sectors) via HDDScan

The utility (ignore the name) allows you to check memory cards, flash drives for bad sectors and read errors.

To diagnose the problem, it is enough to run the sd card through two types of tests - Read and Write tests. After spending 5 minutes of your time, you will get a conclusion: are there any bad sectors that prevent correct operation, because of which the phone does not read the flash drive.

• If the flash drive was purchased recently, we change it under warranty (local or global).
• If there is no guarantee or it has ended, we overwrite the bad sectors with zeros. You can do this through the program. This procedure will allow you to shift non-working sectors, as a result of which the flash drive will be correctly detected both on the computer and on devices where it was actively used.

Formatting with modern digital cameras

A number of Canon and Nikon camera models, according to user reviews, give a positive result - they format at a low level.

How to fix Sd card through camera:

1. Insert the sd card into the device,
2. In the camera menu, find the format command,
3. Try writing files to a formatted card.

Contact technical support (for Transcend flash drives, etc.)

Their technical support specialists can advise free of charge methods for recovering problematic flash drives. In fact, who, no matter how they are, is best versed in the sd card device? In addition, technical support may offer you proprietary programs designed for low-level formatting (sometimes they are difficult to find on the manufacturer's website).

Give the memory card to specialists for recovery

This option is suitable if you are ready to pay for the work of specialists. This procedure is expensive, but the plus is obvious: you can extract data from a faulty device (though, if the memory chips were not damaged).

The memory card is incompatible with the mobile device

Cause. 1) The mobile device does not support new memory cards. 2) The memory card is too large or uses an unknown technical specification. Therefore, the phone refuses to read the data and does not recognize the flash drive as a storage device.

What to do. Carefully study the documentation for the phone and buy an SD card that will not contradict system requirements.

Wrong data transfer mode in Android

Symptom. You connect a phone with a flash drive via a usb cable, selecting the Mass Storage option, as a result, it does not appear on the computer.

How to fix. Instead of "Mass Storage", select the "MEDIA TRANSFER" option when connecting your phone to a PC. Explorer should display the contents of the memory card.

The contact of the usb flash drive has come off or the tracks in the socket have been erased

Symptom. As a result of misalignment or incorrect connection, the memory card is not connected to the mobile device, and, consequently, the phone does not see its contents.

How to fix. Remove the sd card from the phone, insert it back in such a way that the contacts of the sd card are correctly connected to the socket.

If the contacts of the sd flash drive are completely worn out, you can buy them for a couple of dollars and replace them yourself (of course, if you have the appropriate skills / minimal experience in repairing and replacing spare parts).

It is possible that the contacts (that is, the tracks on the board) on the phone have been erased, and for natural reasons, he does not see the flash drive at all. A common reason is the natural wear and tear of the phone. In this case, we recommend that you return the device for repair or replace the mobile device.

Software error, as a result of which the phone stopped seeing the memory card

Description of the problem. A certain Android program refuses to recognize the memory card. Other applications read the sd memory card and write data to the flash drive as if nothing had happened.

Solution. Android does not see the memory card, because in the application settings, the internal memory of the smartphone / tablet is specified as the save source. Go to the settings of the application with which there are problems (for example, Android Gallery or Camera) and specify the sd card as a successor - that is, the place where the files should be saved.

Answers to questions from readers

After updating the phoneHTC desire 620 g dual sim) microsd is not detected, the flash card is constantly lost. It happens like this: for example, I listen to music, and then it stops playing and the phone writes: "the file could not be opened." In this case, the names of the tracks can be read. What could be the reason?

Answer . Check the audio file format. The player may not be able to read the files of the selected format. So the problem is not necessarily the problem of reading the memory card. If the file format is correct, check the memory card for errors, format it.

I inserted an sd drive into my phone (Samsung galaxy j3 2016), transferred all photos and videos to a USB flash drive, and all photos and videos in the phone gallery were deleted. The files are on sd, but all new photos are saved to the device's memory. I need it to be saved to a memory card and displayed in the gallery.

Answer. If the phone does not see the sd card, try changing the path to the successor in the application settings. It would also not hurt to check if your phone and Android system recognizes the actual memory card. Just in case, turn off your mobile device, remove the sd card and put it back. Turn on the device and check if the files are saved to the USB flash drive of the Samsung phone.

1. The phone does not see the SD memory card (flash drive). SMS came, I opened it - and suddenly I stopped seeing it. Rebooted - still does not see. The laptop sees, the other phone sees. And most importantly, the phone sees another memory card. The brand of the smartphone is Lenovo 650. Please help! Thanks in advance!!

2. Does not read the memory card. I have Windows phone Dual Sim 535. For a while, my memory card was readable, but later the phone stopped seeing it.

Answer. In the event that the phone has stopped detecting a memory card, you need to check this sd card on a computer via a card reader (the device is connected to a PC via a USB cable and is inexpensive). In your case, the laptop has a built-in card reader. In order for a phone or tablet to read a card or usb flash drive, you need to properly format it using WIndows tools or using special. software. We strongly advise you to use the free SD Formatter program to format flash drives, this is a method we have tested and often works. We hope that after formatting your phone will see the flash memory and be able to write files to it as before. If the card reader still does not see the memory card, all that remains is to buy a new sd card.

I have a smartphoneSamsung Galaxy Gio S-5660. About six months ago I repaired the charging socket and since then until yesterday I did not turn it on. It had a SIM card and a memory card. When I turned it on, it turned out that the smartphone does not see the memory card. Before that, she had no problems. On the memory card and contacts, books, a bunch of photos. Why does the tablet not see the flash drive and how can I revive it?

I wore the device for repair, I thought that the memory card slot was not working. It turned out that it works: it immediately sees a new card.

Tell me how to return the sd card back to a working state?

Answer. If you don't see a working memory card on your device, it's likely that the file table contains errors. Try formatting the card using the sdformatter application. Since you are dealing with Android, the sd memory card must be formatted in Ext or Fat32.

With the help of the said application, I restored the photo on the Samsung SM-G 318H / DS. They remain in this application, I can’t transfer them to the gallery or to the SD card, how can I do this? Why does not see the memory card?

Answer. Your question is formulated very ornately, so it's hard to say why the phone does not detect a memory card. It looks like the problem is not with your phone's flash drive, but something else. You need to copy the files to the DCIM folder on the device, then they will be displayed in the Gallery again.

I moved the SIM card from the tablet back to the smartphone and all the memory from the phone disappeared. What to do and is it possible to restore photos and contacts if the smartphone does not see the flash drive.

Answer. In your case, probably not everything is so sad. You may have moved the sd card (flash drive), as a result of which it moved away from the smartphone socket. Check the connection between the socket and the phone's memory card. If contacts are lost on the smartphone's flash drive, try importing contacts from the SIM card through the standard Android address book or synchronize contacts with your Google account.

Samsung Galaxy A5 2016 phone. I inserted a 2 GB Qumo sd card into the second slot (for the second SIM card and sd card) ( new map, just purchased). The phone does not see it, either simply through the phone's menu, or through a cable connection to a PC. What could be the reason, somehow you can "reanimate" the memory card?

Answer. Qumo memory cards don't have a very good reputation. However, 2GB cards usually don't have problems when connected to a phone.

First, connect your memory card to your computer via a card reader. If the computer does not see the memory card (the disk is not displayed in Explorer), give the card (explaining that the computer does not see the sd card) to the seller and return the money.

If the sd card is not readable only on the phone, but everything is OK on the computer, try formatting the memory card by selecting FAT as the file system.

The Samsung Galaxy S5 smartphone stopped seeing USB flash drives (I saw and read it before), the smartphone is practically new. Other devices, flash drives are detected without problems. Why Android does not see the flash drive, how to fix the error?

Answer. There can be at least two reasons why the phone does not see the flash drive. Try to fix it like this:

2. It is advisable to format the flash drive in exFAT, otherwise Android may not read its contents.

I dropped my phone and all the photos in the gallery in the camera folder disappeared from the memory card. Can they be restored somehow? The rest of the folders remained in their places.

Answer. Perhaps, or Android does not see the sd card. Check if the sd card works if you connect it via a card reader to a PC. Another reason why the phone does not see the SD card is that the card physically shifted in the slot when it fell, so at the same time check the connection of the contacts.

As for the direct answer to the question: if the memory card is intact, you can restore the photo with any application, starting with CardRecovery and Recuva.

The problem is doubly unpleasant, because the phone was bought a month ago. I decided to transfer some audio-video files from my old phone. The new smartphone is j7, and the old one is also Samsung Galaxy Grand Neo… The data transfer went smoothly.

About a week later I looked at sd, and the map did not appear from my native "my files". I looked through the RAR program, through the xplore file explorer. There all the folders were displayed, but were empty. But it's important to add this: there were music and some video in the phone's memory. So, they were displayed, but they were not "empty", but refused to be reproduced - "playback error". On an old phone with any sd and different ages, this has never happened, so what it was, but not this. And this recorded map can be read normally on the old phone, no problem.

For me, the main thing, as you understand, is the phone, is it the reason? Such refusals in reading for a month were twice with the internal memory, and four times with the seat. Reboot - and everything is fine. But this is not the norm for the phone?

Answer. There may be several reasons for this behavior.

Perhaps the cause of the error lies in your way of copying files from internal memory to external. Try different ways and test: for example, through a card reader on a PC, through a file manager on a phone, etc. Do the described reading errors occur in all cases?

However, since you noted that there are no problems with other flash drives, then there may be a problem with the memory card. Who is the manufacturer, is the sd card compatible with your phone model? Read user reviews.

Third - update the software on the phone and remove unnecessary applications.

Fourth - format the sd card with the SD Formatter utility. Try different file system formats.

1. Last chance to find the answer to my problem. The Samsung galaxy not 5 (china) phone uses only its internal memory, and the flash drive is not detected. What I just didn’t do ... And I put a checkmark, and inserted it into another mobile phone, formatted it this way and that - it doesn’t help.

R.SI moved the card to another phone - he does not see it either. And the computer doesn't recognize it either. What to do? On the flash drive are all children's photos and videos taken in six months.

Answer. If the smartphone or tablet does not see the flash drive, the problem may be in the application that does not save files to the right place. Check in the settings where the files are saved - to an sd card, flash drive or to the internal memory of a tablet / smartphone. For example, in the Android Gallery settings, you can change the storage location for photos.

Re-read the article. If all else fails, then perhaps the phone does not see the microsd memory card, because it is out of order.

The phone does not recognize the memory card. Transferred everything to internal memory. When the card is disconnected, all files are read, but not when connected. Now, when you turn off the SD card, the internal memory is also turned off and there is nowhere to save information. Tell me what can be done if the memory card is not readable (if possible).

Answer. Until this time, the memory card worked? Your phone may not support this card model.

If the sd card worked before, you may need to format your card - and it will be writable again.

The question is formulated incorrectly: you write that when the memory card is turned off, the files are read, while you say below that the internal memory is turned off. So where are the files being read from then?

1. The phone worked with a memory card. With a congratulatory video, they sent a virus that could not be removed. Delete it and it reappears. I tried to reset my phone, but it didn't work. It didn't find any updates. After some manipulations in the recovery menu, he became different, found updates, downloaded and installed them. The firmware shows its own, but with a fresher date.

After that, the sd card is not detected. Android does not see it and does not determine its memory. And other sd too. Without a card, the phone sees its memory and works fine. What to do if the phone does not see the sd card after the actions of the virus?

2. I put an sd card in the computer - everything reads well there, you can see. And in the phone there is an inscription: SAFELY REMOVING THE CARD. Why does the phone not see the memory card? What to do?

Answer. If the phone does not see the memory card, this may be due to damage to the file table on it. How this is connected with the recovery, it is not clear. Try formatting the sd card. If nothing changes for the better - change the firmware.

1. I bought a 4G micro flash drive in my phone, installed it in a computer via a card reader, wrote files and installed it in my phone (Microsoft Lumia 530). After a while, I installed it again in the card reader and connected it to the computer. Windows gave a message that the device is faulty and does not read the USB flash drive, but everything works fine through the phone. And this happens with all usb media and devices.

3. I bought a 32 GB flash drive in my phone from Aliexpress. It worked fine, then the photos that were saved to it were cut off halfway or instead of them there was a gray screen. In the end, it stopped being detected by the phone. The computer seems to detect it, but does not tear it off. Writes something like "insert disk". I tried a lot of things that were written on the Internet, a lot of programs. Some do not see the flash drive, some see it, but still cannot format it.Tell me how to make her feel.

Answer. Format the flash drive via phone or Recovery (we wrote about this at the beginning of the publication.

Answer. Go to Settings - Memory. Check the "SD memory card" section. Install a file manager and see if the files on the memory card are displayed on it.

In addition to standard formatting, you can try low-level formatting - however, not all manufacturers offer their own software for this (check the memory card website).

Another reason why the phone does not see the sd card may be the lack of contact between the memory card and the phone. Check if your device reads other flash drives. If not, take your phone in for repair.

If another memory card works without errors, we advise you to format the problematic card in FAT32 or exFAT - in case the phone does not see the micro SD flash drive due to errors in the file table.

The phone (Samsung Galaxy S5) does not read the memory card. I inserted three cards, and does not read any of them, although they are correctly displayed on other devices. In this case, the inscription "Connect SD-card", the font of which was previously gray, becomes white and available for pressing, but if you press it, nothing happens.

When I insert an sd card into the phone, the device does not detect it. Whatever I tried: even inserted into other phones, still does not see and does not read its contents.

Answer. There is too little information about the memory card (it is practically non-existent) to give specific advice. First, check if your phone supports sd cards of the size that is on your card (see the documentation for your smartphone or tablet). If you have just bought a memory card, you can exchange it under warranty for another one - a smaller one.

If you have previously used this memory card and it is no longer detected on this and other mobile devices, it is most likely out of order.

1. I cleaned the sit card on the computer. Deleted everything from her. Now the new smartphone teXet X-plus TM-5577. I inserted a sit card, he sees it, but nothing is downloading on the sit card and I can’t transfer anything to it. Tell me what to do?

2. The phone started to turn on by itself periodically (Lenovo A 526). Then I went out of the house and plugged in the headphones and noticed that not a single track was playing. Later, when I took out the phone, I found that the flash drive was not readable and the saved music was not playing. I tried to reboot the phone - it does not help, I put it in the card reader - it sees a memory card, I put it in my friend's phone - too. And I don't want to. And the most important thing that knocks me out of my thoughts is a notification after turning on the phone with the phrase "Dismantle the MicroSD before deleting so as not to lose data.

Answer. You need to reconnect the memory card to the computer (as you did before), format the sd card in a standard way(for example, through Explorer) or using sdformatter. The file system is FAT32. Most likely, it is due to incorrect formatting that the phone cannot write data to the memory card.

After a sudden shutdown, the tablet (android 5.1) stopped recognizing the memory cards in the card reader normally. Writes either error checking is in progress, or reading is in progress, which lasts indefinitely. At the same time, half of the programs stop responding, everything slows down wildly, and it becomes impossible to turn off the tablet (only when it is discharged to 0 and cut down). Sometimes (very rarely) after connecting, he sees it, but with the slightest manipulation of the card (even viewing a photo), he immediately loses it and starts re-reading it again, and already with the ends. Tested on 3 flash drives, both clean and not, with different formatting and a bunch of dances with tambourines (all according to recommendations on the forums). The system was reset. Nothing helped. He refuses to see a card for 8 gigs at all, although if you connect it through an adapter to a usb connector, everything works fine (like other flash drives). What is the problem, in the card reader or in the system?

Answer. It is best to connect the problematic memory card to a laptop or, alternatively, through a usb adapter, as you mentioned. Next, the sd card needs to be formatted.

Most likely it's the card reader. Many cheap card readers stop reading memory cards correctly after a short time and give copy errors or read information slowly.

The system (Android) is unlikely to be related to the problem, since you have already tested several memory cards. Perhaps it's a specific application that slows down the system, but this can only be calculated by resetting the phone to factory settings.

Phone Lenovo vibe shot, android 6. costs sony sd card 32gb in the option as an extension of the main memory (ext4). The phone stopped seeing the file system - writes SdCard0 01/01/1970, 00 kb. Windows 7 sees two sections - 16Mb and 30Gb, serviceable, free 100% each.

How can I return everything to its place with the restoration of the old files? well, or at least how to pull out photos and a folder of vatsap?

Answer. R.saver or AOMEI Partition Assistant Standard Edition are suitable for recovering a deleted partition on an sd card. If the file table on the partition contains errors, you can try to fix them using the chkdsk utility under Windows. If it doesn't help, try scanning the sd card (unreadable partitions) with the Recuva utility. Until you overwrite the information on the flash drive or format it, the chances of getting the files back remain high.

Samsung A3 2017 Samsung memory card 64 gb. Created folders from the computer: photos, ringnotes, music, videos, movies, etc. The phone sees only audio, pictures, documents, videos. Other folders do not see on the memory card. What needs to be done?

Answer. Install any file manager for your phone (for example, Total Commander or ES Explorer). Create folders directly through these programs and copy everything you need there. The files should be readable on the memory card without problems. It is also possible that those folders that are not readable from the sd card are hidden or corrupted. So it will not be superfluous to format the card in order to avoid further errors.

Lenovo A2010 phone does not see sd memory card. tried to reboot, writes "Only one sd card is available, it is impossible to perform switching." Other phones do not have a card. In the computer through the card reader does not show at all. Is this really the end, so many photos and videos are gone? Maybe something can be done?

Answer. It looks like there are reading errors on the card or the markup has fallen off. Since the memory card does not open on the computer (i.e., the letter / separate drive is not displayed in the file manager), it makes sense to check if the memory card is recognized as a device at all. To do this, go to diskmgmt.msc (Start - Run) and see if unallocated space appears when you connect the sd card to the PC. If it appears, create a new file volume in this space via the context menu. If nothing happens, most likely the sd card is out of order.

Phone model sony xperia m4 aqua dual. Within two years, a microSD memory card was installed in the phone. Recently, failures began to occur: at first, in order for the memory card to work, it was enough to restart the phone. Now the phone does not see the map at all. Formatting failed. Installed a new one. The phone recognizes it (it is in the settings, the photos were sent to the card), but the applications can not be downloaded from the play store (it still shows the download option only to the phone's memory). What needs to be done in this situation with a flash drive?

Answer. Format the memory card with specialized applications - the same SDFortatter is fine. Next, check the card for errors using the chkdsk tool.

However, you clarified that changing the memory card does not help. The problem may be caused by specific applications or software conflicts within the Android OS. In this case, we advise you to update the firmware or, as an extreme option, reset the phone (perform a hard reset).

Samsung A5 2017 stopped seeing it after encryption of the SD card. Through the card reader on the computer sees, but does not open. Tried to format (SDFormatter, cmd) - does not work. Sees other flash drives. I checked for errors - it gives an error, but does not fix it.

Answer. To check the sd card, use the following parameters:

chkdsk (drive letter): /f/r

• /f - fix file system read errors
• /r - fix bad sectors on sd card

This should fix the errors and allow you to format the sd card in the standard way or through utilities like SDFormatter.

there is a Kingston DTSE3 16G usb drive, the computer does not see it, the flash drive is not readable. Periodically, the system displays a message stating that the device can work faster or. Are there any recovery programs?

Answer. The flash drive supports the USB 2.0 interface. Your computer (motherboard) may have more old version ports, which causes this message to appear. Therefore, we advise you to update the hardware of your PC if you have not done this for a long time.

Recovery programs will not help you, but the correct formatting of the flash drive (in NTFS / FAT) and subsequent error checking through chkdsk will not interfere.

Over the past few years, flash media have become very popular and are used by us, literally, daily, due to its advantages over disk media. It is hardly possible to overestimate its usefulness of a flash drive, because you can quickly write information to it or count it, it does not take up much space in a briefcase or bag, and the price segment is pleasantly pleasing.

Despite all the positive points, sometimes there are situations when it is impossible to read the data due to the flash drive itself or the computer. Indeed, at the most important moment, you can lose access to the stored files, and in order to quickly return everything to normal, you need to have certain knowledge. In this article, we will explore all possible problem situations and find ways to solve why the computer does not see the USB flash drive.

The most common problems why the computer does not see the flash drive:

Flash drive not working

This is the worst scenario for a person whose documents are stored on a flash drive, because it is almost impossible to bring it back to life. You can disable a flash drive by mechanical action on the device chip or its controller, by closing the electrical circuit, or by damaging the contacts on the USB board. This is what a flash drive looks like after an electrical circuit is closed or moisture gets inside the drive.

Determining if this happened to your drive is easy enough. The very first thing to do is to check the flash drive for mechanical damage, chipped cracks, etc. If it is completely broken, you can look for a replacement in a computer peripherals store. If you doubt its inoperability, you can check it with a practical method.

Plug the flash drive into the USB connector of the computer, if the LED on it lights up and you hear a sound on the computer that is typical for connecting a new device, then everything is in order, it makes sense to look for the problem further. If this does not happen, most likely the flash drive is no longer suitable for use.

You can try to take the flash drive to a service center, where the master will try to solder the contacts or replace the controller, but it will be very expensive, and this action will be justified only if you have important documents stored on it. If no fatal malfunction was found and the flash drive shows signs of life, try the methods to restore its performance, which will be described below.

The USB port on the front of the computer is not powered.

This issue is very common among desktop users. Most computer owners are accustomed to plugging a flash drive into the front USB ports because it's fast and convenient.

But there is a situation when, for some reason, during the assembly of a PC, the front panel is not connected to the power system, usually this happens due to the forgetfulness of the computer wizard. Accordingly, your flash drive will not be displayed, despite its full serviceability.

This problem can be solved in two ways. If you urgently need to use information on removable media, you can plug it into the back of your computer. The front connectors will still remain inoperative, but you will get access to documents. It is impossible to call such manipulations a full-fledged solution, so we will consider the second option.

Method number 2 involves connecting the power cable on the motherboard to the front panel of the computer. Depending on the model of the computer case, the connectors for connection may differ. But do not be afraid, they all have markings and you will not be able to connect the wrong connector due to design features. The most common wire types are "VCC", "D-", "D+" and "GND". Moreover, the color marking of the cable and the connector on the motherboard match, but it's better to keep a guide on the inscriptions.

The first step is to gain access to the motherboard, to do this, unscrew the mounting bolts on the case and remove the cover. Locate the cable that leads to the front panel and find the same connector on the motherboard. In the image below you can see what the connector should look like.

It is not recommended to connect on your own, it is better to call the wizard. If you connect the cable and connector incorrectly, you can burn these contacts and even devices. If you decide to connect the front USB connectors, then it’s better to tell us the model of your case and motherboard, and we will show you how to do it correctly and explain what the connector and cable look like.

Faulty or disabled USB port on the computer

Sometimes the problem of unreadable information on removable media is not related to the problem of the flash drive itself, but to the connector into which it is connected. A certain USB port may be inoperative, and this condition can be caused by simple damage to the connector pins. Then not only the flash drive, but also other USB devices will not work in this port.

Decide this problem You can, armed with a conventional soldering iron and minimal knowledge of circuitry. If there is no such knowledge, skill and equipment, then this can be fixed at the nearest service center for a low fee.

However, if there is no reaction to connecting a USB device on all connectors, then the problem may lie deeper. Ports can be disabled in BIOS settings.

In order to connect ports in the BIOS menu, you need to get there initially. To enter the BIOS in the first seconds of booting the computer, you need to press the corresponding key on the keyboard, which is responsible for calling the menu. Most often, the F2 or Del key is set by default, but depending on the motherboard brand and BIOS version, it may be different. On the first image that pops up when loading, it is indicated.

Once you have entered the BIOS itself, we need to follow the following route: “”.

Find the line “ USB controller"So that you are allowed to use the ports, opposite should be the value" Enabled».

After you have enabled the USB ports on your computer, press the F10 key. This will save your settings and exit the BIOS.

USB port dirty

A flash drive is a mobile storage device and therefore is often worn in pockets, briefcases or as a keychain. Due to such operating conditions, dust and small debris can accumulate in the connector. This does not happen often, but it can cause the flash drive to fail. Dust and small debris collects on the contact and prevents connection from the contacts in the port on the computer. Such a flash drive may not only not be displayed at all, but also freeze, slowly transfer or read information and be determined not the first time.

To clean the USB connector of a flash drive, arm yourself with a match and a cotton swab. Wielding a match, remove all debris from the connector, and then moisten a cotton swab with alcohol and wipe the contacts of the flash drive. So you save it from debris and oxidation.

Virus infection

Nowadays, the issue of storage device security is becoming more and more urgent, because viruses are in full swing. You can visit your site social network on the Internet and get infected, not to mention downloading files from unverified sources.

Modern computer viruses can also reproduce, no matter how strange it may sound. They infect files on your flash drive or computer hard drive, and their number grows exponentially.

Very often, the problem of the inoperability of a flash drive is virus infection. The drive is detected by the system, you can hear the characteristic sound of the device connecting to the system, but when you try to read the information, you will see the message "" or " Application not found».

Before solving this problem, it is worth installing antivirus software on your computer and conducting a complete file diagnosis. To access the data on the drive, we need to delete the virus file and scan it. To do this, go to the Start menu and enter the following phrase "" in the search box.

Click on the found element with the left mouse button. You will see a window called " Folder Options", here you need to do the following:

• Uncheck the " Hide protected system files»
• Check the box ""

After that, be sure to press the key " Apply"And only after that" OK», otherwise the changes will not take effect. It should look like this.

After that, go to "My Computer" and go to the folder of the drive itself. There you will see the “Autorun” file, you need to delete it, and check the flash drive for viruses with one of the free antiviruses, the Dr.WEB Cure It utility can do this perfectly.

Now you can fully use the flash drive and no problems should arise. If nothing has changed, then the problem is the lack of drivers, we will analyze it below.

Crashing drivers or using outdated drivers

A very common problem is when a computer does not want to display a USB flash drive due to outdated drivers or their system failure. The failure may be due to a power surge or an unexpected shutdown of the operating system. Or, older computer models may not work with 32 GB or larger drives. We can say one thing, the problem is solved only by updating the drivers.

First of all, you need to go to "". You can do this in several ways, for example, through " My Computer", Or you can find this section in the system search, as we will do.

We go into this menu, after which we connect the flash drive to the computer, after which we open the sub-tab "USB controllers". Select the line " Memory device", By right-clicking the mouse opens the system menu and click" Delete».

Such manipulations allow you to remove the driver installed in the system for your storage device. As soon as you remove it, feel free to remove the USB flash drive from the computer and connect it again. Then the driver on the flash drive will be installed again and the problem will be solved.

If the problem persists, you may need to update the driver for all USB chipsets, this is quite easy to do. You can use the special disk that came with the motherboard, it contains all the necessary drivers. If you do not have it, download the DriverPack program, it will automatically select all drivers for which there is an update and carry out this procedure after your agreement.

Moreover, most users have doubts about the correctness of their actions when they learn about different USB formats. Don't be scared!

Drivers for USB 2.0 and USB 3.0 are installed according to the same principle. And the only difference between the ports is the maximum speed of reading and writing information.

File system errors

The computer may also not recognize your flash device due to file system errors. Let's check if this is so, go to "", how to do this was described above. Now you need to open the sub-tab " Disk devices", if you see your flash drive there, then it is working, and the file system does not perceive it as it should, and, accordingly, does not display it in Explorer. In my case, the flash drive was displayed, which means it is working.

To fix this problem, you must format your flash drive, but this action has several nuances, so we will consider this process in the next paragraph of the article.

If you do not see your drive there, then the problem lies in the malfunction of the flash drive itself, which means that either the controller burned out or the contact soldered off. Specialists in service centers can try to bring it back to life. However, this is an expensive exercise, it is easier to buy a new one, of course, if important information was not recorded on the faulty one and you need to restore data on a flash drive.

File system conflict

Quite often, the contents of the flash drive are not displayed due to a conflict between the file systems on the computer and the removable media itself. For example, if a computer operates on the NTFS file system and FAT32 is used on a flash drive, a conflict situation is not ruled out. Moreover, this problem is common not only in the Windows environment, but also in Mac OS. For example, if you format a flash drive on your Mac device to ExFAT or the standard Macbook file system, then the flash drive is unlikely to be readable on Windows devices.

The very first thing to do is find a computer that uses a different file system, open the flash drive and save the information that is important to you, because after formatting it will be lost.

To solve this problem, we need to carry out the process of formatting the flash drive. First you need to find out what file system is used on your computer. Go to " My computer", right-click on the hard drive, open the submenu and select the item " Properties".

In the window that opens, you will see information about the free and used disk space, as well as find out what file system is used. In my case, the NTFS system is used.

After you know the file system of the computer, we need to format the flash drive into the same system. To do this, right-click on the flash drive and open the Format tab.

In the tab that opens, select the file system into which we will format, put a tick in front of the attribute " Fast"And click" Start".

A few words about why we use the Fast attribute. Firstly, formatting a flash drive will happen much faster. But there is another side of the coin. If there were any documents on the flash drive, then only with a quick format you can restore this data using special utilities. If you did not check the box, then the information that was on the flash drive for you will be lost forever.

Flash drive is not formatted

A fairly common problem is when you insert a flash drive into a computer (mostly a new flash drive and its first use), and the operating system gives you a warning that says that the removable drive needs to be formatted before use. And if the flash drive was used earlier and data is recorded on it, then it will not be possible to access them. Moreover, the volume of the flash drive becomes 0, i.e. as if there is nothing at all, not even a drive.

If you have already used a flash drive and this is not its first connection, then try connecting it to another computer, the problem may go away and you can save the data. But in any case, the flash drive must be formatted. How to do this was discussed in detail in the "File system conflict" section.

But I would like to draw your attention to two points. To avoid problems with the file system (FS) after formatting, find out which FS is used on the computer and install the same for the drive. And secondly, if the information you need was on the flash drive, then be sure to use the “Quick” attribute, so the formatting of the flash drive will take place only by the table of contents, and the lost information can be returned using special utilities.

A problem with a partition or flash drive is automatically assigned a busy letter

There are situations when the operating system incorrectly detects your removable media. Everything seems to be fine, the device connection is displayed and the flash drive icon appears in the tray, but it cannot be used for its intended purpose.

The problem may lie in the fact that the system did not assign a letter to the partition, under which the removable drive will appear, or it assigned it, but this letter is already taken, and this results in an address conflict.

The solution to this problem will be the forced assignment of the partition letter that we choose, everything happens in manual mode. So let's get started.

First of all, you need to hold down the key combination " Win + R", A window with the name "Run" will open in front of you.

In the line we need to enter a simple command diskmgmt.msc, which will take us to the disk and storage management section.

In the storage media manager that opens, we need to define our USB device. You can do this simply, disconnect the USB flash drive and reconnect it, the partition that first disappears and then appears is what we need.

In my case, the flash drive is a drive called "20151114_17", you can also identify it by a special icon. Now you need to right-click on it, and in the menu that opens, select the item " Change letter".

Now another additional window will open before us, a smaller one. In it, you must click on the button " Change"And" Ok».

Now another auxiliary window will open, where you must select any letter of the English alphabet, and after clicking on the button " OK"The letter will be assigned to the section.

It is worth paying attention to one important point! When choosing a letter to assign to a partition on your flash drive, look at what letters are already in use by the system. This is very important, because we may not fix the problem, but leave it. This will happen if you, for example, designate a partition of a flash drive through the letter “D”, which is already assigned to a local disk.

Faulty power supply or excessive current overload of the USB portal

This problem is very common nowadays. The fact is that the computer may simply not see the USB flash drive due to a malfunction of the power supply. Let's figure it out in order, the power supply consumes electrical energy from the network, and then converts and distributes it to all computer nodes. It has a power limit, for example, a 400W power supply will not be able to give you 600W. This means that the consumption of the entire system must be balanced.

Such a problem may appear if you have recently replaced some important node in the system, let it be the processor. Now it consumes much more energy than in the past, which means that it simply does not reach somewhere, and in this case, this "somewhere" is the computer's USB network. Accordingly, the energy consumption parameter must be calculated in advance, and if such a situation has already occurred, you will have to replace the PSU with a more powerful one.

Moreover, the problem may lie in a malfunction of the power supply, it can produce much less power potential than stated and than it gave out before. You will not be able to solve such a problem, since you risk the performance of the entire computer. The only solution is to replace the power supply.

There is another feature of this issue. Recently, USB devices for computers have become very common, for example, now the following devices are powered: a mat for heating a cup, desk lamp, a wireless mouse, a removable hard drive, and in addition, the smartphone is also on charge. And you still want to connect a USB flash drive, but that's bad luck, the computer sees it. The fact is that there was an overload on the current on the USB ports. Those. all your devices are already consuming the maximum amount of current and you will not be able to connect one more. Therefore, in order to use a flash drive, you need to disconnect several devices from the USB ports of the computer and then the problem will disappear.

If the computer does not see the USB flash drive in Windows XP

There are a number of reasons why a flash drive may not be detected in Windows XP. Moreover, the problem can lie both in the operating system itself, and in a malfunction of the flash drive, and even in the hardware of the computer.

If the problem is related to the operating system, then it can be eliminated only by making additional changes in the settings, it is best to do this manually, despite the abundance of special utilities that can help in this matter.

However, if the drive itself is faulty, then the only thing left for you is to try to save the data recorded on it. And after that, purchase a new and more reliable device.

If your computer cannot detect the flash drive, then it notifies the user with the following signals:

• Your flash drive is inserted and you are trying to access the data on it, the message "Insert disk" pops up.
• The system notifies you that the drive must be formatted for further use.
• Errors pop up about the impossibility of obtaining access to data.
• The system may freeze as soon as you plug the flash drive into the computer's USB port.

In this section, we will look at all the most common causes of non-functionality of a flash drive in Windows XP and give practical recommendations for solving them. Carefully read the description of the problem, if it is not similar to yours or its solution did not help you, go to the next paragraph until the problem goes away. The first thing to do is to try to determine if the flash drive is working. This is signaled by a light indicator located on it. If you connected the drive, and it blinks or lights up, then the flash drive is working and the problem lies either in the system or hardware of the computer.

Try changing the port into which you connect the flash drive or even the computer, perhaps only the port or the entire system is faulty, and on another PC the flash drive will work properly. For example, if you see a complete system freeze when connecting a flash drive to a port, this means that this port is faulty and it is better not to use it.

If you are using USB hubs or extension cables and the flash drive is not displayed, the problem may lie in the device itself, and not the flash drive. If this turned out to be the case, you can take the hub to a service center or try to repair it yourself. To do this, you need a soldering iron, solder and a little experience, because most often you just need to solder one or two contacts and everything will work as expected.

Perhaps the problem lies in the lack of electric current in the USB port system. To check this, you need to disconnect all USB devices on the computer (camera, printer, lamp, etc.), leave only the keyboard and mouse. If after such manipulations the flash drive is displayed in the system and you can access it, then the problem lies in a weak power supply. This problem can only be solved by replacing the power supply with a more powerful one, but using a USB hub with its own power source will help to delay the purchase of a PSU.

However, if the problem persists after turning off all other devices, there may still be an actual problem with a lack of power supply power and an outdated USB port. In other words, on older laptops, you won't be able to open a flash drive of 36 GB or more. It will not work here to solve the problem, you can only buy a more modern laptop or computer.

A very common situation is when a user plugs a USB flash drive into the front port of a PC, but the system does not see it. This means that either the ports are not connected to the power supply on the motherboard, or too little power is being allocated to them. You can connect the front panel yourself using the instructions located above in the section of the same name.

Does not see the flash drive due to Windows XP errors. Troubleshooting

The flash drive may also not be detected due to operating system errors. For example, Windows XP SP2 lacks updates and software packages that ensure normal operation of USB devices. Moreover, it is possible that only a few USB devices can work in one port.

The solution to this issue will be updating the system to SP3 and installing the necessary updates. Even a new user can do this, since we only need a couple of clicks, and the system will automatically download, install and launch the update. So, let's get started, we can move in two ways - this is the official download from Windows Update or installing SP3 from a disk or flash drive. The first step is to check which package you already have installed.

Click on the icon " My computer"Right-click and select" Properties». The following window will open in front of you, where information about your system will be indicated.

To install SP3, we need to allow the operating system to search for and update the computer's system. To do this, just go from the control panel to Windows Update.

As soon as you do this, the system will start searching for updates, after which you will be prompted to update all at once or select only the ones you need. If you do not understand which update changes what, then it is better to let the system be updated completely.

After downloading all the updates, the operating system will require you to restart your computer in order to apply the new settings. Click OK and wait patiently. That's all, now you can connect the USB flash drive and use it.

If you decide to choose the updates that should be installed, and not download them all automatically, then here's a guideline that will help improve the perception of USB drives by the system.

Driver conflicts in Windows XP

There is also the issue of driver conflicts. The fact is that some already outdated drivers can cause errors at the system level, moreover, they can interfere with the normal operation of new drivers. A striking example of such a problem is the situation when a user inserts a USB flash drive into a computer, tries to access the data on it, and the system immediately knocks out an error message asking to insert a disk. Or, the system just freezes, and even assigning an existing letter to a flash drive partition is real.

The reason for such errors is as follows. Let's say you have two flash drives, you connected one of them to the system. In automatic mode, all the necessary drivers for this device are immediately installed. you did it necessary manipulations for writing or reading files and pulled out the drive. After that, you insert a second flash drive, which is fully functional, and one of the above errors pops up. This means that the system is trying to use the already installed driver from the first flash drive to start the second one, but they are not compatible.

Reinstalling Windows XP Drivers for USB Devices

This problem can be easily fixed in several ways. Reinstalling drivers automatically or manually. Let's analyze a little theory, the driver from one USB device can be mistakenly used by the system to start another USB device. To eliminate these problems, we need to first remove all available drivers for USB drives, and then reinstall them.

Such a problem may display the message “USB device not recognized”, or inexplicable processes occur at the system level that block access to data or cause the system to freeze.

Remove via DriveCleanup

You can effectively remove all available drivers for USB devices using the DriveCleanup utility. Its advantage is that it searches the entire system for installed drivers and only then removes them.

First of all, turn off the computer, disconnect all USB devices from it in order to avoid conflict situations while the program is running. We turn on the PC, go to the official website of the program and download the executable file. The utility is compatible with any version of Windows, including different bitness. When uploading, pay attention to the file version.

Automatic installation

You have removed all drivers from your computer. In order for the device to function normally, the operating system must have drivers for it. The process of automatic installation of the driver is incredibly simple, you just need to plug the USB flash drive into the USB port, after which the installation will begin immediately. A window will pop up that will display the progress of the installation, on some systems this may occur in a mode invisible to the user. Within one or two minutes, the installation will complete and you will be able to use the device.

Manual installation

Manual installation means installing drivers indirectly from the storage medium itself. We can also install drivers for a flash drive from third-party Internet resources, but in order to avoid conflict situations, we will install drivers for a flash drive using another computer.

So, we take our problematic flash drive, insert it into another computer, where it is recognized. A prerequisite for this process is that the versions of Windows on both computers match. We use system searches and find two files.

By any means, we transfer them to the problem computer, whether it be sending by mail or using other removable media. You need to place these files in a folder with the same path that was on the first computer and confirm the replacement when the corresponding window pops up. We restart the computer and enjoy its performance with FLASH disks.

We have considered only the most common reasons why a flash drive is not displayed on a computer. In fact, there are many more. Moreover, there are problems that are expressed by other system messages, and their solution is already described in the paragraphs of the article.

The message "Insert disk" appears even if the USB flash drive is already connected to the USB port

This system error takes place if the drivers overlap and interfere with the normal functioning of USB devices. In order to fix this error, you need to uninstall all USB device drivers and reinstall them. This process described step by step in this article.

Disk formatting message

This message appears if you are using a USB flash drive for the first time or if a system failure has occurred in it. In addition to the message, you can make sure that it is not usable, because it does not display either free space or occupied space. The solution to this issue is described in detail in paragraphs 8 and 9.

Data error message

This problem pops up in 3 cases. This is a conflict of drivers, a conflict of file systems and a failure of the flash drive itself. It is solved by reinstalling the drivers, if it didn’t help, then a quick format to save the possibility of recovering data on a flash drive. Step by step instructions are above.

Complete system freeze immediately after connecting the flash drive to the computer

This issue has already been discussed in the article, but I would like to draw your attention to the fact that this error can occur for two reasons:

1. Driver conflict.
2. Bad port.

It is easy to check what problem you have, insert the USB flash drive into another port, if the freeze repeats, then it means a problem with the drivers. Instructions and tips for reinstalling them were given as part of this article.

Why does the computer not see the flash drive when the indicator on it is lit

Possible damage to the contact on the flash drive, which is responsible for the transfer of information. A driver conflict and the assignment of an occupied letter to the partition are not ruled out. If the problem persists, after connecting the flash drive to another computer, try checking the accessibility of the partition. If everything is in order here, then reinstall the drivers and the flash drive will work.

Error 43 / Error 43

This error immediately stops reading information from a removable device, which means that we will not be able to immediately access the data. There are several problems that can cause Error 43.

• A malfunction of the device itself is the first of them. Check on another computer if this situation happens again.
• Driver conflict - the solution is described above.
• Updating the hardware configuration - just roll back the driver version in the Task Manager.

conclusions

We have studied in detail the reasons that may prevent the computer from reading the flash drive and the information on it. The described solutions with step-by-step instructions will definitely help you get rid of this problem. The unreadability of a flash drive can only be a sentence if the flash drive is faulty. In other situations, this is an easily reversible process. If you have any questions or you could not find a solution to your problem in the article - leave comments, we will try to clarify the situation together.
