How to fix/repair "CHKDSK is not available for RAW drives" error?

Posted by Juno to RAW Drive Data Recovery on July 20th, 2017

My external hard drive suddenly became inaccessible. When I try to open it, I got a message "The drive is not formatted. Do you want to format it now?" After that, I ran CHKDSK hoping to repair it by myself. But an error message pops up "The type of the file system is RAW. CHKDSK is not available for RAW drives". I have saved lots of important photos and working files on the drive. Is there any way using which I can fix "CHKDSK is not available for RAW drives" error and get my lost data back?
