I have an iPod classic 160gb 2007. I recently had trouble with it and had to restore it. It worked for about a month then I would get the Apple icon but no menu. When I plug it into iTunes, iTunes does not see the iPod. I hold the buttons to restore the iPod and then it sees the iPod briefly and tells me I need to restore the iPod. I follow the instructions and I get a black and white screen that says "Do not unplug, iPod is restoring." But this print is much smaller and it is in black and white. I can leave it restore for days but the screen does not change. The iPod makes clicking sounds but does nothing. I disconnect it form the computer and I get a black and white check mark that says "OK to disconnect". It stays on this screen until the battery dies several days later. I have tried restoring the iPod a half dozen times before I can get to the restore screen in iTunes. When I am able to click on the restore button I received a message saying "iPod could not restore Error 1439". What is wrong? Thank you.
