	The most common reason for this is saying there are more blocks on the
drive than actually exist.  For example, if there are 4 heads, 17 blocks/track,
and 612 cylinders, but 1 block/cylinder is spared out for bad block mapping
(not unusual on a SCSI drive), then you have (I think) the equivalent of
602 usable cylinders (or 612 cylinders of 1 Head, (4*17)-1 blocks/track).
It's ok to lie (within limits) to a SCSI drive.  Note that you should not
tell an A2090 that you have more than 127 blocks/track, it gets confused.
