If your USB drive or SD card doesn’t work after you’ve taken the above mention measures, try using Windows Explorer. It’s the most recommended procedure for repairing corrupted storage. Follow these steps.


Launch “This PC/My Computer”, choose the corrupted storage and right click. Choose “Format” from the drop-down menu and select “Restore Device Defaults” in the popup that appears.


Next, choose “Start” to start the formatting. Before the process takes place, you get the option to uncheck the “Quick format” option if you want the PC to initiate a deep scan of the card/drive. However, this can take some time, so uncheck if you fail with the quick format.


In the dialog box that gives a warning that your data will be wiped, click “Ok”. Wait a few moments for the formatting process to complete. Now you’ll have an error free USB drive or SD card.
Using CMD to Repair a Corrupted SD card or USB Drive

This step includes the use of Windows command prompt (aka CMD). Here, you’ll be entering a few CMD commands, forcing Windows to format the SD card/pen drive.



Below are the steps.


Connect the corrupted SD card or USB drive to the PC. Hover the mouse at the top of the “Start” button and perform a right-click. Select “Command Prompt (Admin)” to launch a CMD window.


Type “diskpart”, press Enter, and then type “list disk” and press Enter again. Now you’ll see a list of all storage devices connected to your PC.


Type “select disk <the disk number>” and press “Enter”. Make sure it’s the correct number. Entering a wrong one puts your internal hard drive at risk. Type “list disk” again to verify the disk number. You’ll see an asterisk symbol before the selected disk’s name.


Type “clean” and hit Enter. Now type “create partition primary” and press Enter again. Type “active”, type “select partition 1” and type “format fs=fat32” and hit Enter. The formatting process will end in a few seconds. If you’re carrying files bigger than 4 GB, you can write NTFS, not fat32. Until the work completes, don’t close the CMD window.
