Doing the following MAY help if the HD is an IDE. Similar could
eventually be done for SCSI, but you would need to figure out the
minor/major values.


create a directory "dev" in /tmp
and execute the following code
----------------

i=254
while true
do
mknod dev/$i b 1 $i
i=`expr $i - 1`
done


for i in `ls dev`
do
echo $i>>dtype1
dtype dev/$i>>dtype1 2>>dtype1 1>>dtype1
done

------------
You will now have a directory with several special devices that can be
"mounted", and a file "dtype1" with a description of each valid file
system in each special file from /tmp/dev.

You can mount the valid entries as normal.
e.g. mount -r /tmp/dev/114 /mnt

and then copy whatever you need.

Note sure if it will work now because of the badtracing bit.
