This is how I create a new FS on my Syquest drive (I would imagine that
the Jaz could do the same thing, with its own disklabel):
new-syquest-disk:
# This won't work if you're using /bin/csh:
d=sd2
disklabel -B -R -r $d /home/proot/bin/syquest-disklabel
# We only want one partition, so using slice 'c' should be fine:
newfs /dev/r${d}c
tunefs -o space -m 3 /dev/r${d}c
syquest-disklabel:
# /dev/rsd2:
type: unknown
disk:
label:
flags:
bytes/sector: 512
sectors/track: 32
tracks/cylinder: 2
sectors/cylinder: 64
cylinders: 4096
sectors/unit: 262144
rpm: 3600
interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0 # milliseconds
track-to-track seek: 0 # milliseconds
drivedata: 0
3 partitions:
# size offset fstype [fsize bsize bps/cpg]
c: 262144 0 unused 0 0 # (Cyl. 0 - 4095)
You can get your own disklabel from your current newfs'd Jaz drive. You'll
probably need to frob a few things like rpm and interleave.
Paul.
