An Added Bonus is that you will have a Backup of iTunes.
the old computer and the external hard drive were corrupted. My entire library is still on my IPOD thank GOD. How do I transfer my library from my iPod to my new windows 7 computer. We tried following the 8 page Apple suggestion and after 2.3 hrs. all that showed up on my computer was data, no music.
