So, if one had an idea of the format of the deleted file, it would be 
possible to do a raw read on the disk in order to try and locate this 
information.  But, Drew's situation, as I recall was that he removed a 
directory or multiple directories.  This truly would be an effort.  But, 
is there some way to identify space that is not currently used.  That 
is, no inode associated with it?  You would reduce the search space 
substantially me thinks.

So, Drew, if you're still talking to me :), could you share what the 
file types were?  (text, image, wordprocessor)

We used to use a tool called fsdb to resolve such issues on SVR[34] 
machines, but I'd guess that's probably similar to LDE.

I didn't have to buy my radio from a specific company to listen
to FM, why doesn't that apply to the Internet (anymore...)?
