I have a huge problem... somehow my ENTRIE iTunes Library is GONE... I know it's probably something that I did, however, all of my music is on my OLD 20 Gig Black and White iPod from 2004 running version 3.1.1. I am currently using iTunes 7.4.0. Here's the question if I plug my iPod to my computer will it copy ALL the music including stuff i didn't purchase from iTunes???
