"I really don't know why 'CHKDSK is not available for RAW drive' error problem comes to my Seagate external hard disk. At first, the Windows 8 just tells me 'the disk is not formatted. Do you want to format it now?' However, in order to protect the left drive data, I cannot format it as it suggests. So, I open the CHKDSK tool and see whether there are some drive damages. However, I merely receive this drive unavailable RAW file system error. Do you have any idea to help me recover data from external drive when it reports RAW? Thanks!"
"When I tried to run a scheduled drive check on my attacked USB hard disk to see whether it got some drive error problems on a Windows 10 computer, it just said: 'the type of the file system is RAW. CHKDSK is not available for RAW drives'. What does that error message mean? My frequently-used external drive is changed from NTFS to RAW file system? What can I do to convert RAW to NTFS without losing data?"
