I just got a new 20GB 3G iPod, but when I put it in the dock to charge or when the hard drive is accessed, this high pitch noise can be heard, it lasts for as long as its in the dock or when music is playing. I doubt this normal but I am not sure. Does this happen to your ipod too?

My 10GB 3G does this, but only when the drive is active.

It's just the hard drive spinning up.
