Hi muggers, i was hoping you could help me out here. I just noticed it now, but i've had my MBP for about a month now. You can't hear it when you're in "typing distance" or when your just normally operating the MBP but when you put your ear close to it you can hear it vibrating and clicking! I don't have this problem in my other macs! (mini, macbook) Now i was researching about it and found out an apple support thread here: http://discussions.apple.com/thread.jspa?threadID=1941829&tstart=105 and it says that the hard drive might just be using its sudden motion sensor to protect the HD from damage. If that's the case then why is my HD doing this? I haven't jolted it or moved it abruptly in any way. All that i know i am doing is 1.) using smcFanControl at the highest setting to provide cooling when i'm using BootCamp, 2.) using BlueLounge's CoolFeet as a laptop stand and thats it. I hope i can get your opinions on this so that i can have an idea if i should go to powermac to have it repaired. Thanks muggers!
