Hello,
I have another problem with the slicing code...
I just got a brand new disk, Conner CFP1080S, geometry reported by boot -v
is (3659/6/96). The standard translation would give me 1030/64/32.
I've been unable to even put a label on it :-(
Probe messages :
Apr 6 02:44:26 keltia /kernel: (bt0:2:0): "CONNER CFP1080S 3939" is a type 0 fixed SCSI 2

fdisk cannot get the correct geometry for it :

I've tried to partition it with fdisk with a fair success and get these
messages :
Apr 6 02:45:51 keltia /kernel: sd2s4: start 1, end = 2097152, size 2097152: OK
Apr 6 02:46:20 keltia /kernel: sd2s4: start 1, end = 2097152, size 2097152: OK
Apr 6 02:46:20 keltia /kernel: sd2: cannot find label (no disk label)
My /etc/disktab entry is like this :
#
# Conner CFP1080S (FreeBSD 2.1.x)
#
# a = /new
#
cfp1080s|Conner CFP1080S 1 GB SCSI-2:\
:dt=SCSI:ty=winchester:\

:oa#0:pa#2097152:ta=4.2BSD:ba#8192:fa#1024:
disklabel says this :
disklabel -w -r sd2 cfp1080s
201 [3:09] root@keltia:~# disklabel -w -r sd2 cfp1080s
write: No such file or directory
and i got this in messages :
sd2s4: start 0, end = 2097151, size 2097152
sd2s4: C/H/S start 0/0/0 (4294967295) != start 0: invalid
Why is this slice 4 ? There is no DOS partition on the disk, only big one
for FreeBSD... I know the disk is more than 1024 cyl even with standard
translation, is this my problem ?
I don't understand (Bruce help !) :-(
