I have a 20" 2.4 Alu iMac i purchased last October, since about March I have been able to hear my hard drive reading/seeking, lately it has been getting a lot louder (if you want to hear it here's a Link) So now I'm beginning to think there's a problem with it, especially as so many people claim to have near silent iMacs, and it's really beginning to bug me. This noise is present when loading apps, loading webpages and basically anything that requires it to be read from the drive. So do i need to contact applecare? (I live in the UK and the nearest 'proper' Apple store is about 50 miles away so i am unable to take it in). Thanks in Advance!
