Are you using the proper controller card for that drive?  When I upgraded 
from a 5 Mb drive to a 20 Mb drive on my Pro I had to get a new controller
card because I was told that all the controller cards were limited as to
what size hard drives they could handle.  Another question that comes to
mind is if you have lots of time you could install the drive into an MSDOS
computer temporarily.  There are tons of MSDOS HD diagnostic programs around
which could tell the status of the boot sector on your ST251.
