This is likely the same problem I encountered swapping a 330 meg ESDI drive for
a 660 meg drive the other day.  The higher capacity drive has 53 (?) SPT as
opposed to the 34 or 35 of the smaller drive.  A WD WA2 is not fast enough to
handle that many sectors in one revolution - the BIOS setup insisted there were only 35 SPT.  Changing to an SE2 (or equivalent from another manufacturer)
should solve your problem.  We used an Ultrastore.
