Hi guys,
Not sure if there is a system for pc's for going from ipod to pc. Best place to look is
www.versiontracker.com. you will need to search for an ipod rip program. these do as it says, rips of your ipod. Great on Macs as you COULD download friends itunes libraries and then transfer them to your hard drive. Also invaluable if you are moving your files from pc to hard drive and want to make sure nothing gets lost.
