How to Repair Corrupted USB Drive and Memory Card Using CMD

Plugging in a memory card and being greeted with an error can be a deflating and scary experience.The first thing
to do is test the memory card using a USB memory card reader and your computer to see if it will recognize the card. If your computer system doesn't recognize the damaged memory card, you can use the Windows "chkdsk" program to repair it.

Step 1
Insert the memory card into your computer’s memory card reader. Use a USB card reader or connect your device to your computer via USB if your computer does not have a card reader. Windows automatically recognizes the device and assigns a drive letter to it. Double-click on the drive letter that Windows assigned to the device. If you can access your data, the card is working.

Step 2
Open Command Prompt. From your desktop, press  Win+R to open the Run dialog. Enter cmd and click "OK" button to bring up a command prompt box. Type the "chkdsk" command and specify the drive letter to check, followed by "/r." The resulting command will look like this example: chkdsk e: /r. Press "Enter" to execute the command and check the memory card for errors.



Step 3
Wait until the "chkdsk" program finishes checking your memory card for structure corruption. Press the letter “Y” on your keyboard to allow the program to continue checking, until you recognize the files and directories that you have saved on the memory card. When "chkdsk" is finished checking the memory card, you're prompted to save lost chains into files. Click the “Yes” option. In a few moments, "chkdsk" will display all of your lost data files that have been repaired on your computer.

Step 4
Then switch to the desktop and double-click on “Computer,” and click on the drive letter that Windows assigned to the memory card. All of the files that were repaired will be visible, and you'll be able to access them again on the memory card.

Step 5
Remove the memory card from the memory card adapter. Unplug the data cable to the memory card adapter from the USB port on your computer. Insert the memory card into the mobile device that you normally use to access the files on it.
