dd the disk and search for the text of the actual file, don't bother
trying to interpret ffs structures, just look for the disk block
beginning with something like:

Disk: /dev/rwd0d
NetBSD disklabel disk geometry:
cylinders: 16383 heads: 16 sectors/track: 63 (1008 sectors/cylinder)

(that's my /var/backups/work/fdisk.wd0)

you will also probably want disklabel.wd0, search for a sector starting with:

# /dev/rwd0d:
type: ESDI
disk: <your disk type, or just end there>

Good luck
