No matter how your USB flash drive or pen drive became corrupted or failed, this method will help.    

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 1: Go to the search bar and type: cmd, hit Enter.
  • Step 2: Click cmd.exe and open Command Prompt as Administrator. (Sign in as Administrator with your account if the program asks for permission).

    Replace j: with the drive letter of your USB drive.

Syntax note
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

Alternative - check disk without Command Line

You may also do this same task using the device properties menu. It can be more intuitive if you are not very comfortable with command line syntax. For Windows 10:

# 2. Recover data from USB flash/pen drive with EaseUS data recovery software

So long as the amount of data you need to recover is less than 2GB, you can get everything back free of charge. If you have a large-capacity USB drive and require further recovery, you can pay for the pro version.

It supports USB pen drive, flash drive or other removable storage devices of all major brands such as Sony, Transcend, SanDisk, Kingston, Apacer, Panasonic, PQI, Toshiba, Super Flash, and Ridata.

In addition to its capability, EaseUS Data Recovery Wizard is incredibly simple to use. The procedure to recover data from a USB drive is as follows:
