While rearranging the partitions on the hard disk of my home computer 
under Linux, I did a stupid thing. My NetBSD disklabel was visible to 
Linux, so I could access my NetBSD partitions there, but I managed to 
inadvertantly create an ext2 filesystem on the root partition. I've 
saved a copy of that partition elsewhere, where it is still visible, 
whereas the disklabel is not now accessible at all.

Is there anything I can do to recover the data from that partition? 
(That's my main concern as I'm happy to re-install)

Thanks in advance,
Gareth Fairey.
