How to recover files when "Chkdsk is not available for FAT/NTFS RAW drives"?

Chkdsk is not available for RAW drives error

Sometimes a damaged volume may look like it lost its file system type. Various error messages may appear, most common being.

The volume X: is not formatted. Do you want to format it now?
The disk in drive X: is not formatted.
There was an error accessing drive X: The disk is not formatted.

Also a CHKDSK tool will complain that it is unable to perform a RAW file system recovery.

The type of the file system is RAW.
CHKDSK is not available for RAW drives.

A case of a customer:

Hi guys,

Hope you can help, this has been driving me nuts for some time now.

Not quite sure what triggered this issue but I have recently been unable to access (play media or music, delete, modify) any files on my internal SATA slave drive (B :\). Everything seems to work ok on the internal primary drive (C :\). Recent files are held on C:\, and then transferred to B:\ for archiving, back-up or when C:\ is running low on space.

I read somewhere that perhaps the permissions or User Controls have been messed up. I disabled User Account Control in Vista and tried to modify permissions, as they were not the same as the directories permissions on the C:\ drive. It worked for most files, but some are still inaccessible, I get the I/O error.

I tried to run a chkdsk on B:\ and get the error "Chkdsk is not available for RAW drives"

But the drives are both listed as NTFS in the Disk Management System.

Any thoughts on how to get the disk working again, or recover the existing data? As it stands I cannot even copy files to C:\ to try and recover them.
