Next, click the "Start" option again and type "cmd" in the "search" box. Right-click "cmd" and then select the "Run as administrator" option. A command window opens and you can fix your corrupt memory card from here.Next, type "chkdsk" followed by the drive letter corresponding to the SD card, then by a colon and /f.

Lastly, check your assigned drive letter to your SD card to verify if the files are recovered or not.

Fix 3: Connect your SD card to a card reader to the system, if your system doesn't assign a new drive letter to it, then it isn't reading it.
