In this section, we will guide you through how to retrieve files from corrupted USB drives using "chkdsk" CMD commands.
- If meeting CHKDSK not working issues, check the tutorial to fix it.
Step 1. Start the Command Prompt by inputting “command prompt” in the Windows search bar. Remember to choose Run as administrator.
Step 2. In the prompt, type "chkdsk H: /f /r" (replace H with the drive letter of the corrupt USB drive) and press Enter.
Also, there are some more available parameters.
- The "/f" parameter is used to fix any found errors.
- The "/r" parameter can fix errors, search for bad sectors, recover readable info, and mark the space as usable.
- To forcefully dismount the corrupted disk, add the "/x" parameter.
- Without any parameters, the command displays disk status without fixing errors.
Method 3. Data Recovery from Corrupted Flash Drives using Windows File Recovery
While local drives allow for file restoration through backup tools and restoring previous versions, USB drives directly delete data, making it seemingly unrecoverable.
What’s more, the functions of “CHKDSK” and “recover” are too limited and inconvenient. However, file recovery tools such as Windows File Recovery can be a solution.
This tool enables users to recover deleted and missing files from healthy, corrupted, or formatted hard drives in batch using commands.
It employs recovery modes and switches to scan for the desired files. The appropriate recovery modes depend on the file system of the hard drive.
|NTFS||Deleted for a while||Extensive|
|FAT and exFAT||Any||Extensive|
To determine the file system, right-click the USB flash drive in This PC and select Properties.
With the file system and recovery mode determined, you could use switches to target your files.
|/n||Filter the scan range: scans for a specific file with its file name/path/type, etc.||All|
|/y:||Recovers specific extension groups.||Signature|
|/k||Recovers system files.||NTFS Segment|
|/segment||Segment mode; recovers files under NTFS drives using file record segments.||Segment|
|/signature||Signature mode; recovers files under all file system types using file headers.||Signature|
|/u||Recovers undeleted files, for example, from the Recycle Bin.||NTFS Segment|
For detailed instructions on how to use Windows File Recovery and understand recovery modes and switches, refer to the provided guide. Now, learn how to retrieve files from corrupted USB devices via Windows File Recovery.
- This app is only available for Windows 10 2004 (Build 19041) and above.
Step 1. Go to Microsoft Store, search for Windows File Recovery, click "Get," and then open the software.
Step 2. Input the recovery command: "winfr source-drive: destination-drive: [/mode] [/switches]."
If you receive the message: “Windows File Recovery failed to create destination folder”, it might indicate that the command syntax is wrong. Please check the tutorial to correct the syntax.
Ensure that the source drive differs from the target drive. For example, using the command "winfr F: D: /extensive /n *.jpg" enables the recovery of all pictures from the USB drive.
How to avoid USB flash drive corruption?
