How to Fix a Corrupt SD Card?

After an SD card gets corrupt, damaged or accidentally formatted, you still have a chance to recover lost data from SD card. If the data loss happened due to the physical damage, then there are hardly any chances of recovery. If data loss happened due to any logical error, then you can follow below-mentioned methods to recover them.

Method 1:

Try to Connect your SD Card to another device rather than the one which is showing error. Sometimes due to incompatibility and other driver related issues, SD Card shows errors. These errors can be temporary or permanent, but if it is not working with any other device too, then it might be possible that you have a corrupted SD Card.

Method 2:

You can try chkdsk command.

  1. For this, you first need to go to the My Computer section. Search your SD Card under “Device with removable storage” section and check what is the drive letter assigned to it.
  2. Once you know the drive letter, click on the Start button and type ‘cmd’ in the search bar. From the menu, right click on cmd and click on ‘Run as Administrator.’
  3. When the command window will open, type chkdsk, write the drive letter for your SD Card, and then put a colon followed by /f. Click Enter.
  4. Once you have given the command, the chkdsk will search for the possible errors and will try to fix it. Don’t forget to check your assigned drive letter to check if the files are recovered.
Method 3:

If you have connected an SD Card to your system through a card reader and your system is unable to read it and doesn’t assign a drive letter, try assigning a drive letter yourself. The system assigns a drive letter to the reader, but sometimes it happens that it still shows the message ‘Please insert the disk into drive E:’ So, in such cases, you need to assign one.

Method 4:

If you can’t access files of your SD Card, but it is visible in the folder, then you can try SanDisk in-built solution. For this, you need to right click on the drive letter and select Properties from the menu. In the properties check for the disk space, if the disk space is showing mostly free, then it doesn’t mean that your files are deleted. In this case, you can use the Sandisk in-built solution.
