  We just installed a 2090 with an ST251 in our 2000 as:
                  6 Surfaces 
                 17 BlocksPerTrack
                 Total cylinders 0-819, or 820

  It's partioned as four 10M partions, ~205 cylinders per part. The
last partion is short because of AmigaDos' use of the first two
cylinders.
  Anyway, the drive (knock on wood) works perfectly.  As far as I
know, the only differences between the 251, 251-1,251N are seek
speed and/or interface (251-1: 28ms, 251N SCSI). 

  So, change the number of heads to 6... That should fix it.
