[Gloucs] How to rescue data from a encrypted filesystem

[David and Sharon]

Having just formatted a drive by mistake, I can recommend 
"testdisk/photorec"  http://freshmeat.net/projects/testdisk/
That pulled out files that I'd deleted ages ago, but how it would deal 
with encrypted partitions I am not sure.  It can be used as a read only 
program so it may be worth giving it a go and putting it in the toolkit 
for future use.  Let us know how you get on.
