Hi everyone, I've got a "problem" on my 13" June 2009 MacBook Pro. Every couple of minutes, the hard drive will start making a "crunching" noise. I'm not doing anything on that computer, it's just sitting on the desk next to me. It doesn't appear to be causing errors or anything, but it's quite annoying. This problem just started today... Hard drive is a 7200RPM 500GB Seagate Momentus that I upgraded in July. Any insight on this would be appreciated... Thanks!
