HDD CLICK sound when picking up the laptop... by design?

    About 90% of the time, I am using the MBP on the couch while watching TV. When I pick up the MBP to move it around, the HDD makes a quiet "CLICK" sound... It does it more when the base is slightly vertical if that helps.

    Is this by design? The first thing I thought it might be doing is preparing for a drop by stopping the read/write. Then again, it may be the ugly sound of a dying HDD. :(


    EDIT: I should probably tell you what I have. Spring 2010 MBP. Specs are in signature.

    Normal is good! I assume they do that to avoid data loss with a sudden drop?
    Thanks BTW for the help! My heart has been eased. :eek:

    EDIT: I am thinking about upgrading the HDD to a 7200 500 GB Seagate. Will the sudden motion sensor follow the HDD or is it part of the MBP?

    Yep, Miles is spot-on its the sudden motion sensor. I believe it`s a function of the Mac itself so it should work on a replacement drive.
    Somebody please correct me if I`m wrong.
