Overview: To recover data from a RAW pen drive, use a data recovery tool like iCare Recovery, which can scan the drive and recover files even without a readable file system. You can also try using the command-line chkdsk tool or DiskPart to format the pen drive and fix the file system, but this risks data loss and should only be done after attempting data recovery.
➤ What Does It Mean When a Pen Drive Becomes RAW?
When your pen drive became RAW, the operating system cannot recognize its file system (FAT32/NTFS). As a result, the device shows as RAW pen drive or RAW thumb drive, and all stored files become inaccessible.

If your pen drive turned RAW format, you can try:

command in CMD (may not always succeed)One of the best free solutions for RAW pen drive data recovery is iCare Recovery Free. It allows users to scan their RAW USB drives and recover documents, photos, videos, and other files. Unlike some tools, iCare does not overwrite existing data, making it a safe first step before attempting formatting or disk repair.
Note: Please do not download nor install iCare Recovery Free on the raw pen drive to avoid data overwriting. You can download and install it on a Windows computer hard drive such as the C drive for instance.
This method is the safest for recovering your data before attempting to fix the drive.

cannot run properly and usually returns the error:
“CHKDSK is not available for RAW drives.”
