ok, here's what you do:
fdisk wd3
<prints out partition info>
pick the one partition that's "sysid 165,(FreeBSD/NetBSD/386BSD)"
then do this:
disklabel wd3sX
where 'X' is the number you got above.. then take the letter of the
partition... a,e,f or g and just do this:
mount /dev/wd3sXx
where 'x' is the letter of the partition.
Let's walk through the process on my machine:
these are my probe messages:
ad0: 2442MB <Maxtor 82560A4> [4962/16/63] at ata0-master using WDMA2
ok, now for fdisk:
/home/bright # fdisk ad0
******* Working on device /dev/ad0 *******
parameters extracted from in-core disklabel are:
cylinders=4962 heads=16 sectors/track=63 (1008 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=4962 heads=16 sectors/track=63 (1008 blks/cyl)
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
sysid 165,(FreeBSD/NetBSD/386BSD)
start 63, size 5001633 (2442 Meg), flag 80 (active)
beg: cyl 0/ sector 1/ head 1;
end: cyl 1023/ sector 63/ head 15
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
<UNUSED>
ok, so that's 1
ok... now...
/home/bright # disklabel ad0s1
# /dev/rad0s1c:
type: ESDI
disk: wd0s1
label:
flags:
bytes/sector: 512
sectors/track: 63
tracks/cylinder: 16
sectors/cylinder: 1008
cylinders: 4961
sectors/unit: 5001633
rpm: 3600
interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0 # milliseconds
track-to-track seek: 0 # milliseconds
drivedata: 0
8 partitions:
# size offset fstype [fsize bsize bps/cpg]
a: 245760 0 4.2BSD 1024 8192 16 # (Cyl. 0 - 243*)
c: 5001633 0 unused 0 0 # (Cyl. 0 - 4961*)
e: 614400 245760 4.2BSD 1024 8192 16 # (Cyl. 243*- 853*)
f: 4141473 860160 4.2BSD 1024 8192 16 # (Cyl. 853*- 4961*)
hmmm, i've got several subpartitions...
mount /dev/ad0s1a /mnt
should work...
best of luck,
