I have an iPod 5G, and so far it works perfectly. Battery runs for 14+ hours. Everything seems to be working as it should. However, it makes clicking sounds when I turn it on, sometimes when it switches between songs, and every once in a while while plugged into the computer (it always clicks when plugged in, just intervals of maybe half a minute to a minute in between each click). I've read this could mean a failing hard drive, but everything else works PERFECTLY. Should I be worried? One more thing... the 'Do Not Disconnect' screen is constantly there when it is plugged into the computer until I press 'Eject' in iTunes. I'm assuming this is because I have it set to 'Manually Update'?
