Why the phone does not see the sd memory card or usb flash drive. What to do? How to make sure that everything is saved to a memory card SD connection is configured
We are all familiar with the situation in which SD card or flash drive stops working or lose the ability to be recognized on different devices. There may be several reasons for this: an outdated or corrupted driver, the presence of malicious software, the RAW format of the drive, and a formatting error.
Regardless of the problem that caused given error, it will not be difficult for you to fix it. In this article, we will look at 3 effective ways restore the visibility of the SD card on a computer, phone or digital camera.
If you are worried about losing important files or photos, at the end we will tell you valuable information on how you can recover a document of any extension from a formatted drive, including an SD card
Method number 1. Update SD card driver
The first thing you need to make sure is the relevance of the installed driver. It is an important link in the functioning of every device on your computer, so if it is outdated or damaged, it can lead to some negative consequences.

2. Open the utility Run using hotkeys Win+R and enter the command diskmgmt.msc.
3. An application window will appear in front of you. Disk Management, which will force your SD card to show up in the list of installed devices.
In the same window, if you wish, you can Open the contents of the map just by clicking on its letter with the right mouse button.
In case something went wrong and your SD card is still not visible to the computer, try the third method.
Method number 3. Remove malware
Often the cause of most of the evils on our devices are viruses that can easily block their functionality. To fix the problem where the SD card still does not want to “come out”, in this method we will look at how to remove the virus that causes it.
1. Connect your SD card to your computer.
2. Open the start menu and run command line on behalf of the administrator.
3. In the window that opens, enter the command attrib -h -r -s /s /d F:\*.*
Instead of F: enter your drive letter. She may be G: or whatever, don't forget to check in explorer.
Data recovery and SD card formatting
In rare cases, the above methods may not be able to solve the problem you are experiencing. The only possible way out of this situation is to format the device. But what about the data?

MicroSD cards are high-capacity memory cards commonly found in phones and tablets. An SD card is considered "installed" (connected) when the mobile device recognizes the card and allows access to it. In most devices, the SD card is automatically mounted when it is inserted into the microSD card slot. If you are using a Galaxy smartphone or Android device, you can connect the SD card manually through the Settings menu. If the device does not recognize the SD card, then the card may be damaged or there may be a problem with the device itself.
Steps
Connecting a microSD card in Android devices
Insert the microSD card into the appropriate memory card slot of your Android device. Before doing this, charge the battery of the device and turn it off. Slowly insert the card until you hear a click. If you can't find a memory card slot, read the user manual for your device or contact the manufacturer.
Turn on your Android device.
On the main screen, tap "Settings". The app's icon looks like a gear. Clicking "Settings" will open a screen with device settings; then click "SD and device storage".
Click Reformat. The reformatting process will prepare the device for installation new card memory and takes only a few seconds. If this process is delayed, restart your smartphone and repeat the described steps again.
When the reformatting process is complete, click "Connect SD card". The device will connect the memory card and make it available for use. If the "Connect SD Card" button is not active, click "Eject SD Card", wait for the card to be ejected, and then click "Connect SD Card". This step will also help you get rid of the Android system crash that prevented the memory card from being connected.
Turn on your smartphone. Press the button at the bottom of the smartphone. If the device does not turn on, then most likely its battery is dead. Connect your smartphone to a power source and wait fifteen minutes, and then try turning it on again.
On the home screen, tap Apps. When you turn on your smartphone, the home screen will open. In the lower right corner of this screen, look for a white lattice icon; under the icon you will see the word "Apps" (Apps). Click this icon.
Click "Settings". The app's icon looks like a gear. Clicking "Settings" will open a new screen. In the upper right corner, find the icon in the form of three white dots. On older Galaxy smartphones (4 and older), you will see the word “General” under the dots. In modern models of Galaxy smartphones (5 and newer), you will see the word “More” under the dots. Regardless of your smartphone model, click on the three white dots icon.
Click "Memory". Clicking this button will open a new screen. Scroll down the screen and look for the "Connect SD card" option. Click this option and wait for the card connection process to complete. If the "Connect SD card" option is not active, click "Eject SD card", wait for the card to be ejected, and then click "Connect SD card".
Device troubleshooting
Remove the SD card from the memory card slot of your device. In the "Storage" section, click "Eject SD card". Wait until a message appears on the screen that the memory card can be removed. Slowly pull the memory card out of the slot to avoid damaging it.
Installation of programs on the internal memory of the tablet is carried out by default. To place the application on the built-in memory card, it is enough to perform a standard installation. It will take a little longer to send it to external media. One simple session of settings will clean up the file system of the device, installing each new application on the SD card.
Option 1: specifying the installation address
Some programs during installation ask the user where to stay. Specifying the installation address is not difficult. Choose a removable memory card, and that's it. But this applies only to some applications, such a minority.
Option 2: Set the installation path in advance
The application must support the app2sd patch if the version of the Android OS on the tablet is earlier than 2.2. There will be no such items in the settings. For all new versions, this algorithm for solving the problem is suitable.
Go to "Settings", find the item "Memory". Click on it and the memory settings menu will open. Here you can also find out about the amount of free memory on your device, how much space is on the tablet in general, how much internal memory is occupied. Some people insert an SD card into a card reader and find out the data about the flash drive on a computer, not knowing that this can be done on a tablet.
Find the "Default Burn Disk" section, which offers you several sources for installing applications. Among them, select "SD-card". Click on this item, and you will see a circle opposite it. Now installing applications on the memory card on the tablet is the default.
Option 3: Using Third Party Programs
Most likely this method will help you. But he demands. You can find out whether or not you have root rights on the tablet by. We download special applications, such as FolderMount or GL to SD, which will help transfer game and program data to an SD memory card. See video instructions below:
Option 3
Install a program on your tablet PC that will allow you to select the installation address. Before installing the application directly, a dialog box will appear in which you will specify the installation address.
This is the most convenient option offered. Because the forced installation of "default" is not desirable in all cases. Utilities such as InstallManager, MagicUneracer will help organize economical and rational filling of the tablet's memory. By the way, these same programs also remove programs with all auxiliary files.
If the application is not installed on the SD card
Open the "Applications" item in "Settings". In the list of applications, select the one you would like to transfer to a removable card. Click on the application icon and a menu will open. See if it has a "Move" option. If there is, press the option button and select the memory card. This procedure does not require the installation of additional software, you can do it yourself.
Unfortunately, the lack of space on the internal storage of Android devices in recent times it is felt quite strongly, because with the development of the capabilities of the “OS” itself, many programs and games have become much more demanding on free resources and the amount of memory of gadgets. That is why many people use removable SD cards. But Android applications on a memory card do not always want to be installed.
General installation information
In any version of the Android OS, installing applications on a memory card is disabled by default. In principle, if the device itself and the OS version support this feature, as they say, there is no need to reinvent the wheel. With a little digging in the settings, you can set your own parameters.
This is a relatively short and simple process, which will be discussed a little later. You can install applications on the memory card in other ways. Let's focus on these situations for now.
Downloading applications to the memory card
Before solving the installation problem, let's consider downloading content to a removable one. The fact is that in Android, installing applications on a memory card in most cases should be closely related to the process of downloading installation distributions, since they can also be quite large volumes.
Downloading content to an SD card is supported by almost all Android devices, regardless of the version of the OS itself or the installed firmware. To set a location for saving files to a memory card, it is enough to enter, for example, an Internet browser and specify removable media as the storage location in the advanced settings. You can do the same in the case of creating photos, when you need to use the settings of the application itself to configure.
You can do it even easier by downloading applications using or a laptop, and then copying them to an SD card. In principle, the download location can also be changed in any file manager.
Methods for installing and redeploying applications to SD cards
Now about the most important thing. Implement the use of installed or already installed applications with a memory card is not so difficult. First of all, you need to see if the device itself supports such features. It also happens that the transfer, and even more so the installation, of applications to removable media is simply blocked by the gadget manufacturer. What to do in this case?
For the Android OS, installing applications on a memory card can be done in several ways. For example, you can first install a program or game using the standard method on an internal drive, and then transfer it to another location (in this case, to an SD card).
For direct installation on the card, you can use third-party utilities. It is clear that the creation of applications for Android in most cases implies the possibility of installing them or transferring them to another location.
Using system settings
If you really need to install an Android application on removable media, you first need to consider several aspects. First of all, you need to go to the settings, where select the "Applications" item, and then go to the settings for the applications themselves. There is a special line "Move to SD card". If the device or application installed on the internal memory supports this function, the transfer will be completed within a couple of minutes, after which an active “Move to phone” button will appear for each transferred program or game.
As it is already clear, in the Android OS, the launch of the application at the end of the transfer process will be done from the memory card.
But do not rush to rejoice. Sometimes both the mobile devices themselves and the creation of applications for android usage such functions are simply not provided. In addition, even root-rights or the use of “superuser” mode (super user) may be required.
Top Programs
There are a lot of programs for transferring either direct or games to removable media today. As a rule, almost all programs of this type are classified as freeware (freeware). True, here it is worth paying attention to the fact that some utilities are very easy to use, and with some professional programs you will have to tinker to understand what's what.
Among the simplest means of transferring programs to removable media are popular packages like AppMgr Pro.
This application automatically analyzes the data of installed applications, and then returns the result in the form of a sorted list, which separately indicates the Android applications that can be transferred to the memory card without any problems. After selecting the necessary applications and confirming the actions, the transfer will be carried out automatically without any damage to the system.
No less interesting is the Link2SD utility. But an ordinary user will have to deal with it for a long time, because you will need to partition the card into partitions from a computer, for example, using the MiniTool Partition Wizard Home Edition software package, one of which must have (Primary), and the second - ext2 (depending on the device and version "OSes" it can be ext3 / ext4). It is in the second section that portable or installed programs will be stored.
The most extreme case can be called the use of a mobile device connected to a computer or laptop via a USB interface. To install applications on a memory card, you will first need to install the program on both your smartphone and your computer. After connecting and synchronizing, you can install applications directly from the control program window from a computer terminal.
There are a large number of software products of this type. Separately, it is worth highlighting, say, Mobogenie or My Phone Explorer, and the second utility supports not only Android devices. Working with such programs is quite simple. You just need to select and specify the installation location of the program (again, if such support is available for both the device and the program).
Forced installation of programs on a memory card
In some cases, you can try to apply another non-standard method. In Android operating systems, installing applications on a memory card by this method is called forced.
The essence of the process itself is to install the ADB RUN program on the PC. On a smartphone, when connected via a USB port, it must be allowed to
After launching the application on the computer, you will need to enter the following commands:
Su - if present (if not, the command is skipped).
pm getInstallLocation("0" by default).
pm getInstallLocation1- installation in the device's own memory.
pm getInstallLocation2- installation on a memory card.
pm getInstallLocation 0- return to default settings.
In principle, there are few commands, but you can see for yourself that this is not the most convenient way. Although in some cases it can be used quite effectively when other methods do not help.
Application Health Issues
It is believed that in the Android OS, installing programs on a memory card is far from everything. After installing or migrating an application, you need to run it and test it. If the launch does not occur, or the program does not work as it should, you will have to repeat the above steps from the beginning. You can try to transfer the application to the initial location and check its performance there. If everything is fine, then the problem is either in the program, or in the memory card, or in incorrectly performed transfer or installation operations.
Conclusion
Summing up, we can say that the most simple and common ways to transfer and install applications to removable memory devices were considered here. Naturally, each utility has its own characteristics, as well as portable or installed programs. Even various modifications of mobile gadgets, not to mention Android OS versions or firmware, can play a very significant role. But in most cases, at least one method will be effective for many.
Hello.
Today, one of the most popular media types is the flash drive. And no matter what anyone says, the CD/DVD age is coming to an end. Moreover, the price of one flash drive is only 3-4 times more than the price of a DVD disc! True, there is one small “but” - it is much more difficult to “break” a disk than a USB flash drive ...
Although not often, one unpleasant situation sometimes happens with flash drives: you take out a microSD flash card from your phone or camera, insert it into a computer or laptop, but he does not see it. There can be quite a few reasons for this: viruses, software errors, failure of a flash drive, etc. In this article, I would like to stop on the most popular causes of invisibility, as well as give some tips and advice on what to do in such cases.
Types of flash cards. Is SD card supported by your card reader?
Here I would like to stop in more detail. Many users often confuse one type of memory card with another. The fact is that there are three types of SD flash cards: microSD, miniSD, SD.
Why did manufacturers do this?
It's just that there are different devices: for example, a small audio player (or a small mobile phone) and, for example, a camera or camera. Those. devices are completely different in size with different requirements for the speed of flash cards and the amount of information. For this, there are several types of flash drives. Now in more detail about each of them.
1.microSD
Size: 11mm x 15mm.
MicroSD flash cards are very popular thanks to portable devices: players, phones, tablets. Using microSD, the memory of the listed devices can be increased by an order of magnitude very quickly!
Usually, when buying, they come with a small adapter so that this flash drive can be connected instead of an SD card (more on them below). By the way, for example, to connect this flash drive to a laptop, you need to: insert the micsroSD into the adapter, and then insert the adapter into the SD slot on the front / side panels of the laptop.
2. miniSD
Size: 21.5mm x 20mm.
Once popular cards used in portable technology. Today, they are used less and less, mainly due to the popularity of the microSD format.
3.SD
Size: 32mm x 24mm.
Flash cards: sdhc and sdxc.
These cards are mainly used in devices that need a large amount of memory + high speed. For example, a video camera, a DVR in a car, a camera, etc. devices. SD cards are divided into several generations:
- SD 1 - from 8 MB to 2 GB in size;
- SD 1.1 - up to 4 GB;
- SDHC - up to 32 GB;
- SDXC - up to 2 TB.
About very important points when working with SD cards!
1) In addition to the amount of memory, SD cards indicate the speed (more precisely, the class). For example, in the screenshots above, the card class is "10" - this means that the exchange rate with such a card is at least 10 MB / s (more details about classes: https://ru.wikipedia.org/wiki/Secure_Digital). It is important to pay attention to what flash card speed class is required for your device!
2) microSD using special. adapters (they usually write adapter (see screenshots above)) can be used instead of regular SD cards. True, doing this always and everywhere is not recommended (just because of the speed of information exchange).
3) SD card readers are backwards compatible: i.e. if you take a device that reads SDHC, it will read SD cards 1 and 1.1 generations, but will not be able to read SDXC. That is why it is important to pay attention to which cards your device can read.
By the way, many "relatively old" laptops have built-in card readers that are not able to read new types of flash SDHC cards. The solution in this case is quite simple: buy a card reader connected to a regular USB port, by the way, it looks more like a regular USB flash drive. Issue price: several hundred rubles.
SDXC card reader. Connects to a USB 3.0 port.
The same drive letter is the reason for the invisibility of flash drives, hard drives, memory cards!
The fact is that if your hard drive has a drive letter F: (for example) and your inserted flash card also has F:, then the flash card will not be displayed in Explorer. Those. you will go to "my computer" - and you will not see a flash drive there!
To fix this, you need to go to the "disk management" panel. How to do it?
In Windows 8: press the combination Win + X, select "disk management".
In Windows 7/8: press the combination Win + R, enter the command "diskmgmt.msc".
Next, you should see a window that will show all connected drives, flash drives, and other devices. Moreover, even those devices that are not formatted and that are not visible in "my computer" will be shown. If your memory card is on this list, then you need to do two things:
1. Change its drive letter to a unique one (to do this, simply right-click on the flash drive and select the operation to change the letter in the context menu, see the screenshot below);
2. Format the flash card (if you have a new one, or there is no necessary data on it. Attention, the formatting operation will destroy all data on the flash card).
Change drive letter. Windows 8.
Lack of drivers is a popular reason why the computer does not see the SD card!
Even if your computer / laptop is brand new and only yesterday you brought them from the store - this absolutely does not guarantee anything. The fact is that the sellers in the store (or their specialists who prepare the goods for sale) could simply forget to install the necessary drivers, or simply be too lazy. Most likely you were given discs (or copied to a hard drive) of all the drivers and you only need to install them.
In general, there are special programs that can scan your computer (more precisely, all its devices) and find the latest drivers for each device. I already wrote about such utilities in previous posts. Here I will give only 2 links:
- Programs for updating drivers: ;
- Finding and updating drivers:
Connecting an SD card via USB using some device
If the computer does not see the SD card itself, then why can't you try to insert the SD card into some device (for example, a phone, camera, camera, etc.) and connect it to the PC already? To be honest, I rarely take out a flash card from devices, preferring to copy photos and videos from them by connecting them to a laptop via a USB cable.
Do I need special programs to connect my phone to a PC?
New operating systems such as Windows 7, 8 are able to work with many devices without installing additional software. Drivers are installed and the device is configured automatically when the device is connected to the USB port for the first time.
For each brand of phone / camera, there are utilities recommended by the manufacturer (see the manufacturer's website) ...
1. Try to connect the card to another computer and check if it recognizes and sees it;
2. Check your computer for viruses (). Rarely, but there are some types of viruses that block access to disks (including flash drives).
That's all for today, good luck everyone!
