    Is it located in the harddrive to detect falls or is it located somewhere else on the laptop. I want to buy a bigger drive or my macbook pro but I can't seem to kind a drive with an accelerometer for sale around. (320GB 7200RPM seagate).
    I mean I don't want to lose the functionality of the accelerometer. I was having fun writing lil apps for it.

    It's located elsewhere. Buy a regular old drive and upgrade. No problems.

    Thread revival go!

    Ok, if I remember correctly, the accelerometer in the MBP is used to park the HD in the case that the system detects a sudden drop....correct?

    Since the accelerometer isn't located in the HD but in the MBP itself, would this mean that it will function with any 2.5" HD I purchased for upgrade?

    I've got my eyes on a particular WD 500GB drive but it isn't one of the "shock resistant" that safe? This is my primary box now so I want to protect the data best I can from movement of the system.

    yup :)
    the acceleromter is used to detect the movement, and is not located in the HDD. So your all good :) If im right, people say that buying HDDs with sensors in and putting them in MBPs actually mess something up as the two work together and it just fudges really.
    So yeah, any ol 2.5, good to go mate :)

    To your left or right
    its ok to have a HDD with its own shock sensor. you will just notice a bit more clicking than a HDD without it.
