Non-sequiter.  SCSI deals with sequential sectors, and the physical
disk layout is unimportant, indeed often unknown, to the user.  There
should be no need to periodically reformat a SCSI disk; they're not
handled the same was as MFM, and you're liable to do more harm than
good that way.  The board that spinrite didn't complain about may
well be doing sector translation too.
