I think the really interesting question is what happens when you lose
a FDE-ed hard drive. Do you still need to publish the incident and
contact potentially affected individuals? If the answer is no, I'm
sure this technology will be quickly adopted, independently of its
actual

One would assume that if you disable the password, the data would NOT be

the entire disk, which would be quite time consuming. It may be that

It sounds to me as if they are storing the AES key used for bulk

password.
I'd say decrypted by the password, rather than unlocked, but that's

First off, it depends on how the thing is implemented. Since the entire
drive is apparently encrypted, and you have to enter a password just to
boot from it, some of the support is in an extended BIOS or some very
early boot code, which is below any OS you might actually
