For the record: You can't pay me enough to try, so I haven't. But with enough grant money... The source I recommend trying (if you haven't already) is Ray Descoteaux at the Center for Magnetic Recording Research (CMRR) for the UC San Diego (rdesc () ucsd edu) http://cmrr.ucsd.edu/people/Hughes/SecureErase.shtml Eric Jernigan Information Security Manager, Technology Solution Services Portland Community College PO Box 19000 Portland OR 97280-0990 503-977-4896 Eric.jernigan () pcc edu http://www.pcc.edu/resources/tss/info-security/ ________________________________________ NOTICE: This email message is for the sole use of the intended recipient(s) and may contain sensitive or privileged information as well as information covered by the Privacy Act, FERPA, HIPAA, and/or other laws.

It may be a labor pain and a half to recover an overwritten drive but the info on the disc may be worth taking to a recovery shop, especially a "no questions asked recovery shop" to pull data from the
drive. I've asked before, and I'll ask again - does *anybody* have any *actual* evidence that recovery from even a single overwrite is in fact possible on a modern drive (as opposed to the barely-doable work in Gutmann's paper from 1995 on MFM-encoded drives)? Fires, dropped in a lake, run over by a truck, 'format c:', are all recoverable. *NOBODY* has, to my knowledge, demonstrated an *actual* ability to recover a single-overwrite. Feel free to cite actual evidence, I've been looking for a decade and still coming up empty.
