    if i understand it correctly, its supposed to lock the hard drive when the laptop accelerates to a certain speed; this is to prevent data loss (if you were to drop it)

    The reader/writer head of the hard drive automatically ''parks'' at its original position to stop it form scratching the disc. :)

    I have this drive. Mine is a Seagate. You can check out the description of the free fall sensor on Seagate's website. By the way, the 200 GB 7200 rpm Seagate is a nice drive. Pretty quiet.

    Good thread I've been meaning to ask this as well since Dell mistakenly gave me a 160GB FFS 7200RPM drive instead of what I ordered (160GB 5200RPM).

    I suspect the danger is that if you are using the computer on a train or something it might repeatedly mistake the swaying of the carriage for drops and keep interrupting the disk access by lifting the heads off the disk. Anyway, I probably would have gone for this shock protection if I could... but I guess it is only effective for a computer that is dropped while it is on. The heads are probably parked anyway for a computer that is in standby or off... so the benefit may not be as great as it might first sound.

    I would think it would need slightly more acceleration than just the side to side swaying of a train.
