Today, after listening to my ipod, and reading some notes, I came home. I plopped the pod into the dock, which wasn't actually plugged into anything--i just set the iPod in the dock itself. The backlight came on and it showed a blank screen except for the title bar which had the pause symbol and "Notes" and the battery bar. Nothing in the main window. I took the pod out of the dock and tried to go back to the main menu. It was making clicking noises like it should everytime I scrolled or pressed a button, but nothing appeared on the screen. Getting a little worried now, I plugged the pod straight into my powerbook--no dock. After a few seconds, an icon appeared on the screen. It was CD with a magnifying glass. There was a loading bar underneath it, but it never made any progress. The icon was animated, but nothing else was happening at all. Now very worried, I reset my pod (menu and pause/play). The apple logo appeared and everything seems to be working just fine.

I guess my question was really this: What the heck happened?? I've never seen this icon before, nor have I ever really ever had my pod freeze like that. Any insight into what happened and what may have caused it? Thanks!
