Send it here: http://www.ontrack.com
Or maybe here: http://salvagedata.com
Or use something like this: http://freshmeat.net/projects/mobiusft/
Or maybe http://freshmeat.net/projects/fccubootcd/
(The latter is reportedly used by the Belgian Federal Computer Crime Unit)
Forensic data recovery is a booming business at the moment (got a friend
who does it, in fact). Just wiping a drive is absolutely not sufficient
- people have been convicted using evidence recovered from a drive
without using "a microscope" (and BTW, how would that help? The data is
encoded in a magnetic field, a microscope won't see that).
