In looking to upgrade my Sun 386i with a second disk, I found out that SUN
uses the Wren IV drives. They also have a variable number of sectors per
track. In my case, I purchased the upgrade from a local distributor at a
fraction of the cost from Sun. However the drive I used was a SCSI
interface. Check /etc/format.dat to see what drives are supported. You may
find a Wren entry for a similar drive.
