Good day,

I was busy decrypting a drive when there was a power failure. After the power was restored, I was happy to see that the decryption process continued once I turned on the PC. It was short lived, as the decryption subsequently paused stating: "This disk has one or more errors. Run chkdsk /r"

The problem is that when I try to run chkdsk, it gives me the following error: "The type of the file system is RAW. CHKDSK is not available for RAW drives."

This is an internal drive (not the boot drive) that was formatted as NTFS and then bitlocker was applied to the entire drive (not just the part that was used)

Please advise how I can get the decryption to resume, or how to get CHKDSK to scan the drive. At this stage I can access the drive, but then it gives me a "cyclic redundancy check" error.

Yeah, I have tried that, which simply opens the bitlocker window that states the decryption is paused because of the errors.

I think I will need something that can fix the errors, even though the drive is in RAW format. In other words, something that will do the job that chkdsk is supposed to do.

Hi,

So the power failure cause the encryption failure and Windows recognizing your drive as RAW partition even it is actually a NTFS file system. That sounds bad. Since RAW is a simply a disk partition that has not been formatted with an NT file system, neither FAT nor NTFS. There is no Microsoft tools can do something about that. We have some practice about how to recover or convert a RAW partition to NTFS, but I am not sure if it works for encryption failure.

Simply searching RAW partition to NTFS or recover NTFS on RAW, you might get lots of suggestions about that.
