I have a 5.0G 30GB iPod that's not quite a year old yet (will be in March), and for no reason at all I just decided to hold the iPod up to my ear and listen to the HD spin up while I connected it to my computer. When I did, I heard the HD spin up but with a screeching noise (like nails on a chalkboard ) and the noise randomly changed pitch. I fiddled around with it some more to see if the presence of the noise varied with different functions, but as long as it was on, it screeched, even if it wasn't doing anything. The screeching isn't an annoying noise issue since I can only hear it when I hold the iPod up to my ear, but I'm kinda worried about the HD screwing itself up. I'm thinking about notifying Apple about it, but I just wanted to see what you guys would think first.
