My hard drive failed a few weeks back. Since I had it replaced I had been working when I had time getting everything off my external back onto the computer and getting it up and running again. Today was the first day I tried syncing my iPad since the crash. It says it can't be synced because it's synced to another iTunes library, but it's the same account. I also had to authorize the computer as if it was a different computer. How do I get my iTunes to think it's the same account as before and not lose all my notes, contacts, bookmarks, and so on? I really don't want to have to start all that stuff over again.
