If you think you've bricked your iPod i.e. USB device not recognised error or something similar, just put your iPod into DFU mode. To do this follow the steps below (make sure you read them all before starting so its a bit clearer) 1. Connect your iPod to the PC and open itunes 2. Hold down the power and home button until you hear the USB disconnect sound 3. As soon as your hear that sound release the power button but keep hold of the home button 4. Let go of the home button when you hear the USB reconnect sound 5. Itunes should then say your iPod is in recovery mode. Click restore and your iPod will be like new =) If at first you don't succeed try again, I find that for some reason it takes two attempts for my PC to recognise its in DFU mode. Also the iPods screen will remain blank throughout so don't expect anything to appear on it.
