ESDI vs SCSI (bus speed)

63 is the "logical" number of sectors, which is a game in the controller to
get you around the 10-bit limit on number of cylinders.  (They fake a
higher number of heads and spt to get the cylinder count under 1024.)  The
disks are physically 34 spt.  They still do run 1:1 and they are pretty fast,
though.
