I unplugged all cord from iPod connecting to my computer, I held the home button and plugged my iPod back in, and then I keep holding the home button until the iTunes sign showed up. I got to the right page and then clicked restore. A small window came up saying " restore and update" I clicked it, I agreed to the terms and agreements and the updating started. The updated finished with =out a problem. I t was when I clicked "restore " that I had a problem. The restoring lasted until I had about 10 or 11 minutes left. that is when I saw a alert of my screen saying "iTunes could not finish restoring,. an unknown error occurred. error code: 0xE8000065" I tried restoring and updating my iPod about three or four times now!
