I bought a 5G 30GB iPod around christmas 05. Recently, the HD failed after i dropped it. Fortunately, my girlfriend had a 5.5G 80GB with a broken screen that she was using for back ups. She gave me the iPod so that i could maybe use her HD in my iPod. I cracked them open and used the Screen, scroll wheel, motherboard from my 5G 30gb, and the HD and battery from her 5.5G 80gb. After i put the two back together here is what happened: I started up the iPod and the apple logo appeared. Shortly after, a screen saying "Connect to your Computer. Use iTunes to Restore." in about 5 different languages. I connected it to my computer, then a message in iTunes showed up saying "iTunes has detected an iPod in recovery mode. You must restore this iPod before it can be used with iTunes." I then clicked Restore and entered in my Administrator name and password. Shortly after that, an alert popped up saying "The iPod "iPod" could not be restored. An unknown error occurred (1416)." This is where I'm stuck. I'm hopping that there are some people on this forum much smarter than i am and who are also willing to help me out. Let me know if i can describe anything further to give people more information about my problem. Thanks to anyone who can help!!!
