    Does anyone hear their hard drive (HDD) scrape (make a little noise) sometimes when they move their computer around? It has happened to me like 5 times tonight. I had never noticed it before.

    Is this normal?

    Yes, that's the sudden motion sensor (SMS). It's designed to protect your hard drive if you drop your laptop. The click/scrape noise is the hard drive quickly parking its head. The newer models (2010 and later) are a bit trigger happy when it comes to acivating the SMS, but still it may suggest you are handling your MacBook a bit too rough.

    I am referring to a late 2008 version. All I am doing is tilting it sideways slightly when taking it off my lap to get off the couch. That isn't considered rough is it?

    Canada, Eh?
    Its definitely the SMS


    It comes with all Apple portables starting from the 2005 PowerBooks.

    Thats not rough at all.
