I'm running a 1.33Ghz 12" powerbook. The past few days, my harddrive has been "whirring"/spinning kinda loud. When I have my powerbook in my lap and its a little bit inclined, it makes the sound. When I brought it out of sleep mode earlier, it made the whirring sound really loudly (it was flat on a flat surface). SMART status says its verifed, i verified the HD with Disk Utility. could my HD be dying or is it maybe just some connector got loose inside?
