Quick question for those with 13-inch MacBook Pros: In a quiet room, do you hear your hard drive spinning? I'm not talking about the head noise it makes when it writes to the disk, rather the noise of the disk constantly spinning. I'm coming from a MacBook Air, so maybe its just the contrast, but I have heard from many people that they can hardly hear the their MacBook Pros yet with mine I can hear a constant whirring sound. Every so often it sounds as if it is going to slow down a bit, but then the whirring is back to normal. I will try to find another MacBook Pro to compare it to later in the week (its impossible to compare to one in a store since there is so much background noise), but in the meantime I'm interested to hear your thoughts. In terms of noise, I would say about its the same noise level as the cooling fan running at 3000rpm. Would you say that's normal with a 320GB 5400 Hitachi CTO? Thanks.
