The hard drive on my 5th G 30GB iPod died and I brought a new one and swapped it out. Now when it is not connected to my mac it displays message "connect to your computer. Use iTunes to restore." For about 5 seconds before turning itself off. When I plug it into my Mac, it shows a "Do not disconnect." message, but does not show up in iTunes or the Finder. It is showing up in System profiler though, but not in Disc Utility. I don't know where to go with this, is anybody able to help me please??!!
