Drive recovery using Linux??

Question about recovery of data.
I have at my disposal a bootable RIP disk and Ubuntu disk (and Ubuntu
system for researching and making CD's :-) ).
I'm trying to recover data from a panasonic DVR device that captured
video to a 20 gig hard disk. The device "died", and swapping out the
drive seemed to get it working, but they need the video off the drive if
at all possible.
I put the drive into a system where I could boot RIP Linux. It saw the
drive as /dev/hda, so the disk apparently spins up and the electronics
I did a p in fdisk, and fdisk reported that there wasn't a partition
table so it didn't know what the filesystem was. Apparently by extension
there wouldn't be a hda1 to mount.
I mounted a network share and am performing a dd if=/dev/hda
of=/mnt/share/filename.img, which seems to be working without error so far.
A) I'm hoping to try to pull information off the img file so I don't
accidentally damage the drive itself. Is there a way to mount it or
root through it for potential data to be pulled out?
B) Any ideas or tips on doing recovery of the disk to restore the data
on it? Do Panasonic DVR's use a raw partition of some kind, like (as I
understand it) Oracle databases do?
I'd appreciate any tips or ideas in my hunt for drive recovery methods.
In my experiences Linux has had some of the best available for people
who don't have access to clean rooms and equipment that cost more than
