Having problems on your android phone or any other with a memory card? Can't read the data from it or the android phone / tablet doesn't detect it?

You can repair a damaged micro SD card if it is damaged using a computer, check it for errors, or reformat it completely.

In general, the fact that the SD card cannot be read is not unusual. If you have a lot of data stored on it and you are actively using it on your phone, there is always the possibility that you may have a problem reading the content.

However, this does not mean that the card should be discarded immediately. There is always a chance to restore the work of the SD card.

If you fail to fix the memory card, then the files on the damaged memory card can be restored -

Sometimes the solution can be to check the file system for errors in saved files, repair bad sectors, format the card, or completely delete the partition (card structure) and recreate it. Below we will look at all these solutions.

How can I restore the functionality of an external SD card

To fix a damaged sd card you will need:

• Windows computer or laptop;
• any way to connect the SD card directly to the computer.

You can connect it to your computer using an adapter - if not, you can buy a USB card reader.

Method one - repairing the damaged CHKDSK file system

If your device writes sd card is damaged here's what you can do. The first and easiest way is to use the Windows system drive recovery tool, that is, CHDSK.

This tool is from Microsoft and is only available on Windows computers. CHKDSK does this without deleting any files, so you won't lose card data.

First, connect the SD card directly to your computer or laptop and launch My Computer or This Computer (Windows 8 and later).

In the list of drives, find the supplied SD card and note which drive letter it was assigned to. For the purposes of this manual, we will assume that the card has been assigned the letter “D”.

Press the Windows Key + R key combination to bring up the Windows Startup window. In the run window, enter the following command to enable the command line: CMD.

A new command prompt window will appear. Now you must enter the appropriate command, which will scan the memory card and fix errors on it. The command looks like this:

Chkdsk D: / f

Of course, instead of "D:", write your drive letter (not forgetting the colon). Press the Enter button to start scanning.

After scanning, you can check your memory drive and see if everything works.

Method two - formatting a damaged SD card

The second way is to fix the damaged SD card by formatting it by deleting all data. This parameter can help if CHKDSK was unable to verify and there are still problems (for example, errors reading individual files).

Of course, you will lose all data, but there is a chance that formatting will fix the card.

To do this, connect the drive to your computer, and then open “My Computer” or “This Computer”. Find the connected SD card in the list of drives and right-click on it.

Select "Format" from the context menu. A new format window will appear for the specified drive (in this case SD card).

Click the "Default Allocation Size" button and make sure "FAT32" is selected as the file system.

You can format with the "Fast format" option selected, but for more accurate results I recommend that you uncheck this box - formatting will take much longer, but it is done more carefully, which can help solve problems with the card.

After formatting, reinsert the card into your smartphone, tablet, digital camera, or other device you are using and make sure the card is working properly.

Method three - completely delete all partitions and re-create it again

An SD card is no different from a regular disk - it can have one or more partitions. By default, there is always only one section.

You can format the card in such a way as to completely delete the partition and leave it unallocated.

This is called low-level formatting. Note that this will also permanently erase all data on the memory card.

After formatting, you can create a new section. This often helps when the memory card appears as "RAW" after plugging in and does not display the partitions that can be accessed.

For such formatting, you can use a program called "HDD Low Level Format Tool". You can download it below.

Connect the drive to your computer, and then run the Hard Drive Low Level Tool.

See a list of all your drives on your computer, including the connected external drive. Find your SD card in the list and select it.

Make sure you choose the right one. Once selected, click Continue and go to the Format this device tab.

The card will be fully formatted and all partitions will be deleted. It will now be a clean, unallocated surface.

That's not all - the card is in such a state that it will be useless. Now go to the "Start" menu and locate the "Windows Administration Tools" folder, and in it select "Computer Management".

A new window will appear. In it select "Disk Management". A new window will appear displaying all drives - both internal and external, connected via USB.

Find your drive with a black surface. Right-click the black unallocated area and select New Simple Volume.

You will see a wizard that guides you step by step through the partition creation process. You don't need to change anything, just click Next. Note the File System field and make sure FAT32 is selected instead of NTFS.

Confirm the creation of the new section. Your micro SD card will now appear in the My Computer window with an automatically assigned drive letter. You can disconnect it from your computer and connect it to your phone or tablet. Good luck.

Hello Oleg! There are many possibilities in your situation. For example, the card may be defective or physically damaged (this will not necessarily be visible from the outside). Let's take a look at the possible options.

Card check with special programs

Checking the card on another phone or device

It is likely that the problem is not with the card, but with your phone. Accordingly, you need to try 3 options:

• insert your card into another phone and check its operation there;
• take another card from friends or colleagues and see how the phone will behave with it;
• make a full reset of the device to factory settings. How to do it correctly - read our article. Do not forget before resetting important data - during the recovery process, all of it will be deleted.

If the problem persists in another phone and your SD card is still under warranty, change it or get your money back. Of course, for this you need to find the purchase documents. If the card is not under warranty or the documents are lost, you just have to buy a new card. But, be sure to make sure before that that the problem is in the card, and not in the phone - do a full reset of the device according to the instructions above. Otherwise, the problem may recur with a new SD card.
