Fujitsu Encrypted Hard Disks

Fujitsu’s new 80-320GB “MHZ2 CJ” drives come with a nice added feature. Not only do they spin at a reasonable 7200rpm, they also have the ability to totally lock you out of your data (And throw away the key). With AES-256 encryption you you can be sure that a forgotten password would wave bye-bye to your data. Currently, AES has yet to be broken in a feasible way, leaving a lengthy brute-force attack as the only option. I question the implementation, as we have seen a number of problems with hard drive passwords which are stored on the drive in the service area. Quite often the passwords become corrupt leaving the user locked out of their drive.  The only way to overcome hard drive passwords is by low-level firmware repair, effectively removing the password. This is likely not an option with disk encryption as you would expect a much more robust system. 
Whichever way you look at an encrypted drive, it could  cause major problems to people needing data recovery. Is it just a clever marketing scheme in a paranoid market or is there some really secure basis for the new technology. I can’t wait to get my hands on one and find out.
