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

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,
