Hi, so ive had the new macbook pro 15" for a week. and ive noticed that the hard drive clicks every now and then. kinda sounds like this http://www.youtube.com/watch?v=6V_S45q0mrg This doesn't happen when im moving the macbook around (so im thinking its not the SMS), it just makes the noise when im using it on the table maybe every half an hour or so. Also, recently ive noticed that, when im watching a video on VLC, it freezes/stutters for less then a second and makes that click sound (from the hard drive). Does anyone know whats wrong with it?
