I am working on a small problem here.  I have a 2 Gb Quantum XP32150 that I
would like to connect to my hp300 running NetBSD.  I found the following
information when the drive was still connected to my Mac:
Blocks:      4 199 760
Cylinders:       3 922
Heads:              10
Sectors/Track:     109
Bytes/Sector:      512

Now when the hp300 system boots up with the SCSI disk attached it reports a
cylinder count of 3 907.
sd0 at oscsi0 targ 0 lun 0: <Quantum, XP32150, 55D4> (SCSI-2)
sd0: 3907 cylinders, 10 heads, 4199760 blocks, 512 bytes/block

I was able to fill in the disklabel to this extent:
# /dev/sd0c:
type: SCSI
disk: XP32150
label: 
flags:
bytes/sector: 512
sectors/track: 109
tracks/cylinder: 10
sectors/cylinder: 
cylinders: 3907
total sectors: 4199760
rpm: 3600
interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0		# milliseconds
track-to-track seek: 0	# milliseconds
drivedata: 0 

Now the sectors/cylinder should be simple math
4199760/3907 = 1074.93217302 ???

So what do I do?
