Or it could be possible that the port itself is damaged which is blamed for the corrupted pen drive, so try another different USB port. If no problem is found, then you need to consider the following methods to repair the corrupted device.

Method 1: Fix the corrupted SD card by formatting it

Formatting is always the first and foremost solution that most computer users come into mind when trying to repair corrupted SD cards. Moreover, they would go for File Explorer or Disk Management to format the disk, but sometimes the formatting process won’t go smoothly, even raising some new error like Windows was unable to complete the format, or Format volume is greyed out.

So what else you can do to repair the corrupted disk? Maybe you can think about using CMD. This process involves Windows command prompt which is commonly known as CMD. Therefore, you have to enter some CMD commands to forcefully format your corrupted pen drive/SD card. Below is the detailed guide.

First of all, open the CMD window: click the Start button, input “cmd” in the search box, right-click Command Prompt, select “Run as administrator”.

Then type the following command and press enter after each.

Diskpart

list disk: a list of all the storage devices connected to your computer will be displayed.

select disk <the number of your disk>: (example: select disk 2).

Cautions: Make sure you enter the disk number correctly. Otherwise, you may format your internal hard drive.

Clean

create partition primary

active

select partition 1

format fs=fat32.

The corrupted SD card can be forcefully formatted in a few minutes. Don’t exit the CMD window until the formatting is completed.

Method 2: Repair a corrupted flash drive without formatting (check& fix the bad sectors)

If directly formatting the corrupted drive is the last method you will try since it erases everything important, then you can check whether there are some bad sectors on the pen drive or SD card, then fix it. Also, you could run the CHKDSK to check the disk error, but if the command prompt isn’t your thing, please attempt an SD card repair tool called AOMEI Partition Assistant, that is available for Windows 10, Windows 8.1, Windows 8, Windows 7, Vista, XP.
