The Free Tools: USB Flash Drive Repair Utility & Data Recovery Software

When you search ‘USB flash repair software’ or ‘pen drive repair software’ on Google, you can easily find a large number of hard drive repair tools that all advertise to be able to repair pen drives and recover data. But few of them actually work as well as they advertise. Most software can only scan or find some existing data on the corrupted device.

To fully resolve the USB corrupt error, you'll need more than just third-party repair software. This is where Window’s disk check tool - chkdsk steps in. Use chkdsk to repair the device, then turn to powerful hard drive data recovery software to get all of your data back.

The Procedure: Repair a Corrupted/Failed USB without Data Loss

The first step is to check the disk and repair its errors. Afterwards, use data recovery software to recover any missing or inaccessible data.

#1. USB/pen drive repair tool - CHKDSK utility

To repair the USB drive we will use the chkdsk utility within Command Prompt. There is also an alternative that does not use the command line that is shown below.

  • Step 2: Click cmd.exe and open Command Prompt as Administrator. (Sign in as Administrator with your account if the program asks for permission).

j: -- The drive letter. Replace with the letter of your USB drive
/f -- Will attempt to fix any errors on the disk
/x -- Will force the USB drive to be dismounted before initiating the scan
/r -- Will scan for and attempt recovery of bad sectors. It will take a longer time to scan the sectors and is optional, but it might be worth checking for bad sectors if your device is having issues
If you decide to use it, enter: chkdsk j: /f /r /x
