Just got an 80 gb classic. I know its HD based so this is probably stupid, but is it normal to hear the HD once in a while when rapidly cycling through the songs? clicking and whirrling sounds? I thought these things were quieter than that by now Its not constant, but I hear it when running through songs with the forward button. But again, sorry if its a dumb question I'm use to flash players.. My portable 120 pocket HD is practically silent, so I didn't know if this is something to worry about or not.
