Thanks Nils, I plugged the thing back in, used fdisk /dev/sde and it 
came right up. I removed the existing one and made a new /dev/sde1 of 30 
GB and saved it. Then I unmounted the thing and used mkfs.ext3 /dev/sde1 
and it did that exactly right.

The next thing is to put this Ubuntu on it with all the stuff attached 
for a good backup using dd. Then if the worst happens I can dd it back.

Or rsynch perhaps.
