Someone linked me this article a couple calling into question the
ability to actually read overwritten data:
http://www.nber.org/sys-admin/overwritten-data-guttman.html

I'de love to read something from the other side, showing real examples
of getting usable data off of a disk that has been overwritten / wiped
/ etc

any links or info?
