I've just added a new IDE disk to my FreeBSD 3.4 system. Following the
steps outlined in the Handbook (and the tutorial) I have not had any
luck getting the disk to actually mount. I'd appreciate it if someone
could perhaps shed some light on this situation.
I created a single dedicated slice, 'wd3s1', covering the entire disk.
After creating the slice, I exit (but don't write the slite, per the
warning about adding new disks to do that in the label editor) and go
to the label editor.
I [C]reate a new File System partition covering the entire disk, and
give it a dummy mount-point. I then [W] the partition, get the
expected error about mounting /dev/wd3s1e on the dummy mount point,
then choose [Q]uit.
I add the following entry to /etc/fstab:
/dev/wd3s1e /d1 ufs rw 2 2
and attempt to mount the new disk:
davis# /sbin/mount /d1
mount: /dev/wd3s1e on /d1: incorrect super block
OK. I search the archives: the only question about a similar response
from mount relates to CDs, which the answer was the specify the OS. So
I try that:
davis# /sbin/mount -t ufs /dev/wd3s1e /d1
mount: /dev/wd3s1e on /d1: incorrect super block
Here is the output from disklabel:
davis# /sbin/disklabel -r wd3
# /dev/rwd3c:
type: ESDI
disk: wd3s1
label:

bytes/sector: 512

rpm: 3600
interleave: 1
trackskew: 0

headswitch: 0 # milliseconds

drivedata: 0
8 partitions:

e: 39876480 0 4.2BSD 0 0 0 # (Cyl. 0 - 2482*)
Any and all help is *greatly* appreciated. It would be really nice to
have that 20G drive working.
Thanks in advance,
