- # SCSI drives
- #
- # NOTE: The Builddisk application and /usr/etc/disk now are able to
- # automatically determine SCSI disk geometry and capacity for SCSI disks
- # that support the MODE SENSE command -- no disktab entry is required.
- #
- # Currently, these programs will build single and dual partition disks, so
- # disks requiring 3 or more partitions must still be specified in /etc/disktab.
- #
- # If an entry is specified in /etc/disktab it will be used in
- # preference to the default parameters chosen by /usr/etc/builddisk and
- # /usr/etc/disk.
