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.
