Did you try a low level format?  Get into debug and at the prompt(-) type
in g=c800:5 and return, then follow the directions.  ST225 has 4 heads,
615 cylinders, 21.4MB capacity, step pulse range 5-200usec, ave access time
65ms, recording method MFM, write precomp = 300, land zone = 615.
Goodluck!  Hope this helps!  Oh, I just assumed you had a WD controller.
An adaptec controller uses g=c800:ccc, a Konan KXP-230 controller uses
g=c800:6.  If this is an AT which I doubt it's a type 2 drive.
