The above are just a few out of many things that could damage your SD card. Next I will show you how to repair a damaged SD card.

   Method 2: Changing The Drive Letter

Sometimes the SD card might not be corrupt. Rather the drive letter is the issue and as such you will need to change it.

  • Open Disk Management by pressing Win + X.
  • Locate and right-click the SD card and then select “Change drive letter and path”.
  • Click Add and choose a new drive letter. Save changes.

This should get your card up and running again. If you lack technical know-how or the methods don’t work for you, you can go ahead to try out third party applications. A good example is EaseUS.
