I've got a 3g 20gb iPod. The other day it won't let me use the buttons & just skipped though every song, so I left it to go flat. The next time I went to use it, it showed the folder & !, I've now got it back connected with my iBook & it's showing disk mode, & doesn't show up at all either in finder or itunes. I had taken it away on vacation, & this started on the first day, so I've had no music on holiday!! Just before I went away I was trying to put it on the dock & it won't go & I noticed that it was open slightly at the bottom, I think something has got in & damaged the disk as it's making a noise like it's trying to get the disk to work. Ideas, anyone?
