Hey guys, new to mac, awesome laptop! Anyways, anytime i move or jerk the laptop i hear a click coming from my HD, after reading everyone says its the sudden motion sensor. Today I brought my laptop to my computer guy & good friend who is a genius with computers & he didnt like the sound of it & said that the HD could eventually fail cause it sounds like its skipping & that I should get it replaced asap... Just wondering is this standard in every MBP? It only happens when moving the laptop around, otherwise its perfect. Im probably gonna take it in to apple also & see what they say.. Thanks a ton!
