Thread: primary and copy boot sectors are not matched

i am having some issues with my hard drive. i wanted to undelete some files but my d drive was not showing in the undelete software. it was saying "undelete not supported on drive". rest of my drive were working fine with the software. Tried this wih other software but the same problem. tried the check disk utility as well, but still not fixed.
