Looks like your heads can't write to reallocate the bad sectors. If it was me I'd try editing system file 93 and see if the changes stick, if they don't more than likely heads can't write. After this it's up to you to try turning reallocation off in RAM or swap the heads and write it to the system file.
Thanks a lot skinbob
Actually sys file 93 is unredable ,drive goes to non ready state ,I think head transplant is must for this case.
