Hi, I have an issue with my internal HDD. It's a Hitachi Travelstar 5K750 and is prone to a soft clicking noise. This click tends to happen when the laptop is idle but also when it's simply been on a long time. The clicks can range from intermittent (every 10-15 secs.) to quite rampant (every 2 secs.) Putting the laptop under heavy use can silence the clicking but it is still there and quite torturous when I'm using Word or Photoshop as concentration is effected by this irritating sound. I've been reading various things around forums about messing around with Advanced Power Management but my laptop doesn't have any APM feature. Does anybody have any solution to this?. Laptop cost $1200 and it seems quite a shoddy piece of hardware for this price. Thanks in advance!
