Mark, the data is still there, but it cannot be decrypted. Ever. The key
that was used to access the data before has been irrevocably destroyed. It
cannot be retrieved by hardware or software. Even if you knew what the key
was, which you wouldn't as it never left the drive, there's no way to get
it back onto the drive. Thus, while not "erased", it is unreadable and as
such meets DOD, NIST, EU, and a host of other standards that protect
companies from data breaches.

Matt,
Do you have a dog in this fight or something? The data isn't gone just
because you changed the key. It's still on the platters of the disk
until it's overwritten X times and can't be forensically retrieved.
Thanks,
Mark

Subject: RE: DISK Sanitizer Help
In the future, when you replace these disks you may want to opt for the
new self-encrypting disk drives. It makes these discussions of disk wiping
a thing of the past.
Instead you simple change the drive encryption key before handing them
in for warranty replacement or for sale and all data on the drive is
rendered useless.
