Hello. Don't worry with this raw file system problem. In face there are some better ways to fix such partition problem.
When partition is marked as raw file system
, it may state that there are some freeware that could let you fix such raw partition or drive problem on your hard disk drive, usb drive, memory card etc.
, it works to get you out of such raw drive problem.
Just one thing, it is command line built, not very user friendly.
However, there are one tip that you should keep in mind.
If you have data on the drive that marked as RAW, you should use some freeware like icare data recovery free
to get deleted files restored before you use testdisk.
