How Do I Fix a Corrupted Flash Drive Without Losing Data?

The simple way to do that is to get a professional data recovery software to retrieve those files and automatically fix/repair the USB drive during the recovery process. However, there are still other ways to get it done. Hereunder are the different ways to recover data from a corrupted flash drive or USB drive.

Fix File System Errors

By fixing Windows' file system errors, you may be able to re-access the files you saved on your removable USB drive. Here are ways to fix file system errors on Windows OS computers.

  • Open File Explorer and navigate to My Computer or This PC
  • Look out for the flash drive, right-click on it and select "Properties"
  • Toggle to the "Tools" tab and click on the Check button under "Error checking"
  • Wait for Windows to automatically find and repair any issues with the USB Flash Drive, then you can open the drive and access your files.

Note: This method does not work in all cases.

Use Windows CMD Utility

Another way to fix flash drive corruption without using a third-party application is through the CMD utility. Windows OS comes with a built-in CHDSK utility that helps you check for file system errors. However, to run the CHKDSK utility, you must have admin access on the computer – then follow the steps below.

  • Connect the corrupt flash drive to your computer
  • Launch the Command Prompt utility as an admin (Press Windows Key + X and select Command Prompt (Admin) or PowerShell (Admin)
  • Run the following command in the command prompt console: chkdsk /X /f E: (replace E with the drive letter of your flash drive – check File Explorer to see the actual drive letter)
  • Wait for the processes to run completely, then close the CMD window, restart your PC, and try opening the flash drive again.

Use a Free USB Repair Tool

DiskInternals Uneraser and Partition Recovery are both freemium software programs for repairing corrupt external storage drives and recovering data from them. These software apps allow you to scan corrupt flash drives to retrieve your lost files and preview the retrieved files for free. Below is how to get started.

When you finally find the files you want to access, you will need to upgrade to the PRO version of the DiskInternals software you chose before you can save the files back to your PC.

Recovering Files from a Logically Corrupted USB

When a USB drive or flash drive is logically corrupt, it won't appear in File Explorer when you plug it into a computer, thereby making it difficult to scan the drive and attempt to recover your important files. Storage drives can get logically damaged due to quite many reasons, but not to worry, there's a way around it – here's how to deal with logically corrupted USB drives.

1. Set a New Drive Letter

To start with, you need to assign a drive letter to the USB drive, and this has to be done through the Disk Management page. Basically, even though the flash drive isn't showing on File Explorer, for the fact it is connected to your PC, you'd find it in Disk Management.

  • Press the Windows Key + X and select Disk Management
  • Right-click on the USB flash drive's number and choose the "Change Driver Letter" option
  • Delete the existing drive letter and enter a new one from the drop-down list
  • After changing the drive letter, go back to File Explorer and try to access the drive.

2. Reinstall/Update the Drivers

Sometimes the issue is driver updates – try reinstalling or updating your Disk Drivers and see if the issue is fixed. To do this, go to Windows Device Manager, look out for the disk drivers tab, expand it and update all the drivers you see there; you can as well uninstall those drivers and restart your PC, and they'd automatically reinstall as the system boots.

3. Use CMD To Check For Device Errors

Open Windows Command Prompt as an administrator and run the CHKDSK command: chkdsk E: /r /f. Remember to replace "E" with the actual drive letter of your USB drive.

4. Use Data Recovery Software

A data recovery software may be your best bet if all methods explained below don't work for you. DiskInternals Partition Recovery is a professional solution that can help you repair corrupt/damaged USB flash drives, as well as recover your files from the drives.

Step One:

1. Download The App

Download and install DiskInternals Partition Recovery software on the PC. Then launch the recovery software.

Step Two:

2. Launch The App

Select the file formats you want to recover (you can select all file types) and proceed with choosing a recovery mode. The Fast Recovery (Uneraser) option recovers recently deleted data; choose the Full Recovery option for wholesome recovery.

Step Three:

3. Choose a Recovery Mode

Wait for the scan to run completely (it may take a long time, depending on the data volume), and you’ll see all your lost files indicated with a red asterisk. You can preview the recovered files for free before proceeding to re-save them or export to a remote storage via FTP.

4. Preview The Partition

Note: While file preview is free, saving the recovered files requires the license.

Recovering Files from a Physically Damaged USB

If the USB drive is physically damaged, it may be difficult – if not impossible – to still get back your files from the drive. However, hereunder are some tips that may work for you.

1. Adjust the USB

When you insert the USB, try wiggling it gently to see if the computer will recognize it. Sometimes, the issue could be the flash drive's touchpoint having slight touches, so wiggling the drive could make it come in contact with the pins in the PC's USB connection port, and then the drive will appear in Windows Explorer.

2. Check for Any Debris Obstruction

There could be tiny debris in the USB flash drive's pin or the connection port on your PC. Hence, you should check the two ports/pins for possible debris and tiny particles that may be hiding inside. If you find any, blow them off or try using a pin to remove them carefully. After that, reinsert the USB drive and check if your computer can read and open it.

3. Recover Corrupted USB by Contacting Professional Recovery Services

If you tried all that has been shared in this article and yet could not get your files from a problematic flash drive, your next best bet is to contact a professional recovery service center. In such centers, specialized tools are used to try reading and access the data stored in the flash drive – they can help you retrieve your files so you can save them on another drive.
