So, I ran CHKDSK command in Command Prompt hoping to repair it, only to find that "The type of the file system is RAW. CHKDSK is not available for RAW drives."Is there any way to fix this error and get my lost data back? -answers.microsoft.com
This is a real case discussed in the Microsoft community. If you are also annoyed by getting "The type of the file system is RAW. CHKDSK is not available for RAW drives" error, it means:
- Your drive's file system is corrupted or unrecognized by your operating system.
- CHKDSK (a repair tool) can't fix RAW drives.
A drive becomes "RAW" when its file system is damaged, making all data on it inaccessible. If the drive is too damaged, CHKDSK won't work, and you'll need other solutions to recover the data or repair the drive.
This article will tell you why CHKDSK reports RAW file system errors, and also offer you solutions to repair the "CHKDSK is not available for RAW drives" error and recover all the data from RAW drives.
Two steps to fix/repair CHKDSK is not available for RAW drives error
As the CHKDSK command can't repair the RAW file system, and according to the recommended ways in other articles, you may want to fix that problem by converting the drive's original file system to another type. You can convert RAW to FAT32, exFAT, and also convert RAW to NTFS. But unfortunately, after running "convert g: /fs:ntfs" in CMD, an annoying error message pops up again: "CONVERT is not available for RAW drives."
In this situation, if you still want to fix RAW drive, you should format RAW drive and assign a new file system to it. If there's no data on your drive or you don't want those files on it, feel free to perform the formatting. But if you have very important data stored on it, you should recover lost data from the RAW drive first, then fix the RAW drive by formatting. Because reformatting will wipe all your documents on the drive, so be careful!
