Last night it just stopped responding....I would select a song and it would bring the song up but not play it. I put the iPod up to my ear and I could hear the hard drive stuck in a cycle of "spin up, clickety click, powering down (sounded more like power dying though...sick sounding), and the platter come to a noisy slowdown/stop." I did a hardware reset, and now it plays songs, but the hard drive is still behaving that way. Is that how a healthy iPod sounds?
