If you're dealing with iPod trouble of hanging screen "Do not Disconnect" or "Ok to Disconnect", follow my instructions, it'll be fine.
1. Unplug iPod from any cable connection.
2. Press and hold Menu button and Center button at the same time for about 10-15 seconds.
3. When a rebooting screen appears ( a white apple ), wait for seconds then enjoy again....!
Have fun!
