You have probably already lost the data, but it is possible that 
a different copy of the file is located on the drive. If you've 
restored a backup you are probably screwed.

Sometimes programs will store files in a temp directory or when 
they save the file it won't overwrite the old one, but delete it 
and make a new one.

These can be recovered in many cases as long as the data hasn't 
be overwritten by other files. They may not exist on the file 
system but in the free space, you have to use an undelete program 
that does a low level scan of the file system for deleted files.
