Mine was making a noise without a disc in it, But, It only started making that noise after I did the update. So, It must be the update... I've never dropped it before, dropped it on the sides, or anything... i was fooling around with a disc in, and it never made a sound.... then when I took the game out, it started making the noises.... but what ev, I just ignore it... If it continues hardcore, like majorly, then I'll take'er apart and try to find the source.
