[plug] partition recovery - stupid fdisk mistake

Thu May 18 12:15:17 WST 2006

Thanks Tim, Mike

I have recovered table info using Mikes suggestions so it is just a matter 
of manually entering partitions.

This is a good oportunity to try the gpart idea and see if it comes up with 
sametable info currently in /proc/partitions. If it doesnt I'll let group 
know for future ref.
