I needed to restore my iPod touch 1st gen. So I plugged it in and clicked restore. It popped up a message warning me that all my data will be erased. I then clicked agree to the SLA and etc. It popped up this message after a few seconds. I recently put a fresh install of Leopard on my MacBook. Instead of exporting my iTunes library to disc to back it up, I just copied the iTunes folder on the hard drive onto my external hard drive and back into the new install of Leopard, could this be why?
