Hi all I just receive a new macbook pro 15'' 2.8ghz the drive is a 500gb Fujistu, every 1 or 2min I can hear a click from the harddisk even my computer isn't moving at all nor am I surfing anything much, not running any other app beside safari. I don't remember having this problem on the older unibody 2008 model before. Although SMART and disk utility didn't show anything wrong. and I also ran backup occasionally, but definitely don't like the sound of this clicking. anyone else having this?
