Hey guys, I'm having this weird issue... When I shut my MBP off, just as the power cuts out theres what sounds like a whirring or something that seems to come from the front of my Core 2 Duo MacBook pro. Theres no disc in the drive and when I boot it up there's a really quick version of the noise almost like soft grinding. Heres a video of it: http://www.youtube.com/watch?v=DdiruPoMzzI&feature=youtube_gdata_player you have to listen closely since its a little quiet... There are no noises emitted from anything when it's actually running. What could it be? It's not a dying HDD is it? Thanks everyone!
