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?
