Hey is it normal that the new unibody 17'' features louder HardDisk accessing noises? I didn't hear any at all on my previous (late '08) but now i'm kinda annoyed by them. It's not really loud but once you're aware of it and know the HD makes these noises in same intervals it's really annoying. Especially when it's really quiet and you're trying to focus reading articles and other things. Anyone out with same experience? Any idea if there's a way to make it go away (i guess not)?
