Micro SD flash drive not readable Android does not see a flash drive (memory card) microSD

The situation when the computer does not see the card reader occurs for several reasons: a file system failure has occurred, a drive letter conflict, incorrect connection, incompatibility of the card reader and memory card. To solve the problem, you need to use a special utility, format the USB flash drive, connect it to another device, or reset the BIOS settings. The card may be damaged, so when connected to a laptop, the user will not be able to open the files located on this media. Older laptop models have a built-in card reader that cannot read modern SD cards. The solution to the problem is to purchase a new card reader that has a USB connector. You can open a flash drive through a camera or phone by connecting the device via a USB cable to a computer in order to copy the necessary files stored on this media.

Checking card reader drivers

The user must first make sure to insert the SD card in the correct direction. The device should show how to insert it.

If the appropriate drivers have not been installed on the computer, the SD card will not work. In this case, the flash drive cannot be found in Disk Management. To check the card reader drivers, you need to go to the "Device Manager" and see if there is a question mark next to the desired device.

There are two ways to access Device Manager:

1. In Windows 7 and 10, you can log in through the Control Panel.
2. Use the Win + R key combination to call the "Run" menu and enter the text "devmgmt.msc" in the field. Then you should click "OK".

If there is no problem with the drivers, no icons will be displayed next to the device in the USB Controllers tab. If there is no card reader in this list, you need to install or update drivers for it. To find desired programs you can use the automatic search. If a CD was included with the device when you purchased it, you should download the programs recorded on it.

If the automatic search did not give a result and you do not have a disk, you need to go to the official website of the manufacturer and look for drivers there. The user can click on the "Update configuration" button in the "Device Manager" (see image below).

Troubleshooting programs

If the laptop prompts you to format the flash drive when you start it, it sees the device, but cannot recognize its file system. In this case, a message is displayed, as shown in the figure:

This is due to an error in the file system of the card, or the OS cannot read a system that is unfamiliar to it. This problem occurs after connecting the flash drive to the TV. Checking the device with the troubleshooter will help resolve this situation. You can use the chkdsk utility built into Windows. To call it, you need to run command line and enter in the "cmd" field. Then press the "Enter" button and enter the following text: chkdsk g: / f (the letter f indicates the disk of the sd card) and press the enter button.

If the problem was a system failure, after the procedure is completed, the card will become readable again. If the utility did not help and the formatting message reappears, you need to restore the files on this device (if they are of any value to the owner). You can do this with free programs: "Recuva", "Pandora Recovery", "R.saver". When resuming information, the data must be installed on the hard disk.

Section title conflict

Checking the drive letter in Disk Management will fix the error if there is a character conflict (the OS assigned the flash drive a letter that is already in the system). Procedure:

If the reason is not in the conflict of letters, then the desired card will not be in the list. If the file system is RAW, the SD card will need to be formatted.

Reset BIOS settings

You need to check if the corresponding slot is enabled in the BIOS settings. If not, then select the desired device in the section with ports and check the box next to it.

You can reset the BIOS settings after restarting the computer. You should press F2 when a black screen with numbers appears. For some manufacturers, the "Delete" key is used to exit the BIOS. Each device has its own BIOS, which is different from the rest. The name of the section with devices is "Miscellaneous Devices", the designation of the sd card is "SD Reader" or "Media Card Reader".

Mechanical damage

Checking for mechanical damage to contacts will most likely help solve the problem of the invisibility of a memory card on a laptop. To make sure that the card works, you need to try opening it on another computer or laptop. In case of failure, it is recommended to replace the flash drive, as it is not working. If another device was able to recognize removable media, but it malfunctions, the problem is mechanical damage or dirty connectors.

You need to take a cotton swab and moisten it with alcohol, and then wipe the contacts on the back of the flash drive. Do not pour liquid on the memory card and insert it into the port until it is completely dry. If, after the contact cleaning procedure, the memory card worked on another laptop, but still does not want to start on the computer, you need to clean the flash drive slot with a special nozzle with compressed air.

The problem may also lie in a card reader that does not support certain types of sd cards. Information about the compatibility of the device can be found on its packaging or on the official website of the manufacturer.

If none of the methods brought the desired result, you need to check your computer for viruses. Some malware blocks access to removable media and makes it invisible. You can use the built-in Windows diagnostic program to let the OS find the problem and fix it.

Hello everyone, hello! Your phone does not see the memory card? Was there important data on the flash drive? In this article, I will tell you why the memory card may not be visible on the phone, and I will also share my ways to restore a flash drive.

At the same time, I’ll say right away that the accessory could simply break down, but in 50% of cases it’s a software failure that can be fixed on your own without contacting a specialized cell phone repair service.

The instructions and tips below apply to all phones, including older models that cannot be classified as "smartphones". This topic is especially relevant for those users who have important data left on the phone. Sometimes it is impossible to restore the performance of a flash drive in the phone itself, but it is possible to transfer data to a computer using a card reader.

After studying today's article, the user will learn:

1. Why flash drives stop working.

2. How to check the status of the memory card.

3. How to format a flash drive on a computer.

4. Formatting the memory card using phone functions.

5. Memory card malfunctions and their causes

Important! If you are installing a flash drive for the first time, then the reason for the lack of its work may be in the volume of this drive. This applies to older phone models that are not designed for large memory cards.

The phone does not see the memory card

And now study the main malfunctions and possible ways to solve them:

- The file system is damaged - the memory card can be restored by formatting (the most common malfunction);

- In the flash reader of the phone, the contact of the drive has moved away - you need to firmly insert the USB flash drive and restart the phone;

- The flash reader is out of order, respectively, the phone does not see the memory card - repair in the service center will help here;

- The flash drive burned down - of course, it can no longer be restored. Although you can still try to recover data, here is one of my articles in which I told you how I recovered data from a burnt flash drive.

So let's continue. Now you need to check what exactly happened to the memory card. First of all, restart the phone, sometimes such an elementary action is enough to fix an error in the file system of the drive. Did not help? Remove the battery (if the flash reader is behind the battery and not on the side) and check if the flash drive fits snugly against the contacts.

The next step is to test the flash drive on another device. The easiest way to do this is with a card reader: just put a USB flash drive into it and connect it to your computer. If there is no reader, then insert the USB flash drive into another phone.

If the memory card is read on another device, then the problem lies in your device. To find out the details, you need to take it in for repair. Sometimes it's just a bug in the software, and sometimes it's a broken contact. If the memory card is not visible on other devices, then it either burned out or its file system was broken. In the second case, formatting will help. Also, in some cases, you can repair a memory card using simple commands, which I talked about in this article:

ATTENTION! Formatting will delete all data from the flash drive. If you are not sure that the cause was a software failure, then it is better to immediately take the memory card for verification. For those who want to try to "reanimate" a flash drive, I have prepared two simple instructions. If your phone still does not see the memory card, then read on.

Formatting a flash drive on a computer: step by step instructions

You can format the flash drive on your computer using a card reader. If not, then go to the second instruction. And now on the topic:

1. You need to put the USB flash drive into the card reader, and then insert it into the appropriate slot in your computer or laptop.

2. Now we are waiting for the automatic launch of the flash drive on the computer. If this does not happen, then go to "My Computer" - there you will see a new device (if the flash drive has not burned out).

3. Right-click on the mouse icon and select the "Format" item in the context menu.

4. After that, the formatting menu will appear. You need to select the file system of the flash drive: "NTFS" or "FAT". By default, for almost all cards, the FAT format is selected, but if this formatting did not bring results, then try choosing NTFS.

Check that everything looks like in this screenshot:

Now click on the "Start" button and wait for the process to complete.

Now the flash drive can be inserted into the smartphone and check whether it worked or not. If the problem persists, then you should try the second instruction. Sometimes the card is not readable after being formatted on the phone due to the partitions that Windows creates when it is formatted.

Format flash drive on phone

The phone sees the memory card, but still can't open it? Then we format it right here. We insert the drive, check the contacts and go to the memory settings. AT Android phones you will find this option in the memory options. In this section, you must click on the "Disable card" or "Eject" button, as shown in the screenshot:

Now press the "Clear memory card" button. The process will take no more than a minute. After that, you need to select the item in the menu "Connect SD-card". In addition, I recommend that you watch the following video:

It is worth considering that, depending on the Android firmware version, the path to this function may differ. Formatting flash drives in gadgets with a different operating system is the same process - you need to find the "Memory settings" section.

So, summing up today's article - “The phone does not see the memory card”, it will be necessary to add that if formatting did not help, then you can immediately carry the memory card to a service center or buy a new drive. I hope that my article helped you recover a flash drive. It's especially good if you were able to do it without formatting.

Recently, more and more often 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 purchasing and using these cards, please read important nuances their applications.

• 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 looks 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 that can be connected 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 malfunctions operating system, for example, Windows may incorrectly assign the drive 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.

In some cases, the phone does not see the microSD, but not all users know why this happens and how to fix the problem

Moreover, this problem is serious, since it does not allow access to all the information stored on the flash drive.

For users whose phone is a player, a device for Internet surfing, such a problem can be a serious problem.

The essence of the problem

How does this problem manifest itself? How to understand that the phone really does not see the device? This is quite simple and becomes clear immediately after installing a memory card.

The device does not reflect that it was installed. At the same time, there is no memory card icon on the panel on the home screen, nor is removable media displayed in the Memory section in Settings.

Accordingly, in all directories of the phone (for example, Music, Gallery) there are no corresponding files, before .

Sometimes, after installing external media into the phone, the device does not immediately display a message about its installation, as it usually does.

Sometimes, while working with microSD, it may suddenly turn off, and a message will appear on the screen like "Memory card disabled".

In the most rare cases, the device reports damage to the memory card.

A problem can occur both on a new device and on an old one. And also with both the old memory card and the new, empty media. Regardless, the causes are often the same for all cases.

Possible reasons

There are several reasons for this phenomenon. Conventionally, they can be divided into two large groups: problems with the phone and problems with the drive itself. The first group includes:

1. Direct damage to the memory card slot;
2. Other hardware problems in the device;
3. Functional problems software, due to which the device does not see .

From the side of the memory card itself, there may be the following problems:

1. Device failure (especially when a previously working card suddenly ceases to be recognized or the device reports its malfunction, which is typical for old memory cards with great wear);
2. Physical damage to contacts on the card or other problems;
3. File system mismatch (some newer file systems don't "see" old phones, then it shows that the drive is missing).

Depending on the cause of the malfunction, certain methods of its elimination can be selected.

<Рис. 2 Слот>

elimination

There are several ways to deal with such problems. They are selected depending on the cause that caused the malfunction.

If this reason is not clear, then you will have to try several methods.

Working with hardware

<Рис. 3 Контакты карты памяти>

First of all, you need to check what exactly the problem is. Install another memory card in the device, and if it is detected, then the problem is in the drive itself.

If not, then the problem is most likely in the phone.

What can the user do in this case? It is recommended to clean the card slot from dust, as well as wipe the contacts on the carrier itself. You can do this with a cotton swab.

Most likely, this does not solve the problem, but sometimes it helps. However, if it turns out that the card slot is broken, then the only way will be his replacement.

Recovery

<Рис. 4 Восстановление>

Each has a Recovery mode. Its launch will allow you to “roll back” all questionable settings to factory settings.

Thus, if the device previously saw cards, but now it does not, then this method can help.

1. To get started, perform a normal reboot of the device (not turning it off and on, but just rebooting);
2. If this does not help, proceed to recovery;
3. Hold down the power and volume down buttons at the same time and hold for up to 10 seconds (most often, access to the recovery function is opened in this way);
4. As soon as the device restarts, a special start menu will open in Windows;
5. Go to the Wipe cache partition item in it (you need to do this with the buttons or by clicking on the screen, depending on the device);
6. Reboot the machine (rebooting may take much longer than usual).

The map should now be defined. If this does not happen, then you will have to work with it on a computer.

Formatting

<Рис. 5 Форматирование>

Insert a memory card into a computer using an adapter. Open it through the "My Computer" section in order to make sure that the device is working.

If the computer does not see the drive, then such a memory card is faulty.

1. Press Win + R and wait until the Run window opens;
2. In it, write the command diskmgmt.msc;
3. A window should now open showing all memory devices - external, internal, formatted, not formatted;
4. If the letter designating the card matches the letter of, for example, an optical drive, etc., then you need to rename the card;
5. In rare cases, renaming may solve the problem;
6. If the problem is not solved in this way, then you need to completely format the card and create a new file system (of course, it is worth remembering that the data from the media must be copied before this);
7. You can format the device from Explorer;
8. Click on the memory card with the right mouse button;
9. A menu will open in which you need to select the line Format;
10. A window will open in which you need to remove the marker from the box next to the inscription "Quick Format";
11. Specify below that you want to create a format file system (most often this option is set by default);
12. Click OK;
13. Wait until the end of the process.

Then install the memory card in your phone. It should be successfully recognized. If this still does not happen, then it is possible that there is still a specific hardware malfunction in it.

Restoration of work

<Рис. 6 Восстановление через ПК>

Restoring the operation of a MicroSD card is a specific case when a media that was successfully recognized earlier suddenly ceases to be recognized by the same device.

At the same time, there was no damage to the carrier or phone, no changes were made to the phone software, etc.

Also this method can help when the phone says that "Unable to access memory card", "The memory card is damaged, etc.".

This method is quite effective, but only for older cards. And only on condition that they worked properly before. For new cards, this method is useless.

1. Connect the memory card to a PC or laptop to make sure it is working;
2. Open Explorer and right-click on the map;
3. Select Properties from the drop down menu;
4. Go to the Service tab;
5. Run Check disk, having previously indicated the need for automatic correction of detected errors and malfunctions;
6. In the same section, you can Surface test with automatic recovery of bad sectors (although this is not necessary).

A more complex option is troubleshooting by working in the HKLM branch. This is done as follows:

1. Find the SYSTEM directory in the folder tree;
2. In it, open the StorageDevicePolicies section;
3. In the right part of the window, the parameters that need to be changed will appear;
4. Assign a zero value to the defining parameter (write the number zero in brackets in the combination 0x00000000(1)).

Now the card should interact normally with the phone.

File system

<Рис. 7 Файловая система>

There are microSD HC and microSD XC memory cards. The second option is typical for cards with a capacity of more than 32 GB.

They have a different file system, which has its own advantages (for example, recording speed and length of recording segments), but is not recognized by all phones, tablets and other devices.

Thus, some phones are simply not designed to support cards larger than 32 GB. Changing the file system in this case is almost impossible without special skills.

However, it is worth remembering that the type (HC or XC) of the card is written directly on it, so it is important to choose the right one.

WHAT TO DO IF THE ANDROID (PHONE) DOES NOT SEE THE MEMORY CARD?

The phone does not see the MicroSD flash drive: what to do, how to fix it?

Nowadays, it is much easier for users to store the information they need. It is absolutely not necessary to load the PC memory, since there are many third-party elements - flash drives, CDs and DVDs. Micro and miniSD, as well as regular SD, are also very popular.

Each of the proposed tools may malfunction. This manifests itself in the fact that as soon as the user removes the removable media directly from the mobile, camera and other device and inserts it into the PC connector, the computer simply cannot detect the SD.

There may be several reasons for this development. In some cases, this is the result of the action of viruses. Also, banal errors may occur during the user's work. Often the reason lies directly in the inoperability of removable media.

Species diversity of SD cards

It is worth paying attention to the most common causes of problems. But before that, it is worth finding out exactly what types of flash cards exist. Almost all users confuse one card with another. Manufacturers have developed several types of SD.

There are special elements for mobile devices. There are also cards for photo and video equipment. So each type of device has its own tools. This is due to the different requirements for the amount of stored information and the speed of operation.

microSD cards are very popular. Such elements are inserted into mobile devices, tablets and players. With the help of these objects, it is possible to significantly increase the memory. This makes it possible to save much more audio and video recordings, photos.

Complete with such devices, users are encouraged to purchase special adapters. With their help, you can connect SD cards to a laptop. Not so relevant, but still often used - miniSD. These assistants are also suitable for portable equipment.

SD cards are excellent devices that have free memory from 8 MB to 2 TB. Such a large amount of size is necessary for users for DVRs, cameras. At the same time, the cards are able to function at speed with excellent performance.

Features in the process of working with flash cards

Each such element contains information about the speed of the object and the class of the instrument. When selecting a card, it is necessary to take into account which class is required for a particular device. You also need to pick up a special adapter. It can be several assistants in one set.

In many "weak" personal computers, developers have provided for the presence of built-in card readers. But these assistants are not able to recognize the new types of SDHC cards being used. But even in this situation there is a solution. Users will need to purchase a card reader that will connect to a regular USB port. Such connectors resemble standard flash drives.

Reasons for not recognizing flash drives

In some cases, just one drive letter can prevent the detection of removable drives, including flash drives, external hard drives. Anyone hard drive and flash drives, the letter F can be spelled out. For this reason, it is impossible to recognize the connected device.

To quickly fix this, you will need to go to the panel to manage all disks. This path is different for different versions of the operating system. If Windows 8 is installed, then you need to simultaneously click on the Win + X buttons and hold down. In the context menu that appears, select Disk Management.

For OS version 7, you need to click on Win and simultaneously press R. Next, you need to enter a simple command "diskmgmt.msc". Immediately after that, a new window will open. All disks and other connected devices will appear in it. You can also see formatted devices.

The desired flash card will be shown in the same list. Immediately after that, you should change the original version of the letter to a unique version. It is necessary to make adjustments to the context menu that appears immediately after right-clicking on the desired object for storing data. Next, we carry out formatting, during which the drive will be completely cleared of information.

The next common cause is the lack of drivers. Even if the user works with a new device and constantly updates the necessary components, this is not a guarantee that the device will work in normal mode.

If by chance it was discovered that at least one driver was missing, then you can use special assistants. Thanks to the utilities, it is possible to detect a package of the necessary drivers for each device. It is enough to enter a request on the network to search for a utility to update drivers.

Once these actions are implemented, it will be possible to immediately proceed to the next stage. In some cases, users try to insert an SD card into any device. Only after that we connect a mobile device, a camera with a flash card directly to a personal computer. To do this, use a special USB cable.

In some cases, users try not to use additional utilities. Only owners of new versions of the operating system can afford it. Windows systems. Then the process of installing the necessary drivers and the subsequent configuration of the PC parameters is performed without user intervention.

In other cases, the very first time you connect a device to a dedicated port, you will need to download additional software. There are unique drivers for all device models. Users need to pick them up and install them. Only after that the used memory card will be visible on any computer.

So users can solve the problem in several ways. Rodin of the proposed options without fail will be effective. It is only necessary to carry out all the steps correctly to ensure an excellent result.
