Well, I bought a 500 GB d2 Quadra a little while ago, and I just noticed it makes some funny noises every once in a while. While running it's usually pretty quite (I DO think I hear the humming of the drive though... But it's barely noticeable, and it might just be my PC...), but when I power it on it makes a sort of "vroom" (kinda like a futuristic space shuttle type thing?
) and when powering off I just heard a click... I was just wondering if this was common or not. =S
