   I don't have the spec right here.  I think it amounts to (with the
   FreeBSD utility)

   scsi -f /dev/rsd0.ctl -e 3 -P 3        # Manually edit the format
					  #  device page to set sector size.
   scsi -f /dev/rsd0.ctl -c "4 0 0 0 0 0" # Format.

   "-P 3" select parameter set 3, the permanent ones.

Careful readers will note that this interface really *sucks*, and it's
very easy to do something completely different than you intended.
