yea newer desktop drives offer the same "solution", course soon as your computer craps with the drive locked your stuffed, so I dont recommend it (I had a nice collection of HA HA drives in this situation for a while)

software based solutions which I would imagine HDT is using is probably wiser (just in case you spill a cup of coffee while the computer is just starting to post)

sorry I don't have any relevant information to share about the topic though
