I was using my iPod with the iTunes we had in our Mac G3 and everything was working fine. Then, I wrecked the G3 by accidentally putting over a gig of files on the desktop. The only way I can fix it is to reload the operating system. This will wipe out everything on the G3 hard drive. My question is this: when I get the G3 up and running and plug in the iPod, will I need to re-format the iPod? Will I have to start all over again as far as loading songs on the iPod? It took a lot of time to select and put those songs on the iPod.
