Hi everyone- I have a 5G iPod, a G4 Powerbook and a firewire external hard drive. To free up disk space on my Powerbook, I was considering moving my iTunes library over to the external drive (and updating all settings/preferences accordingly). I was wondering, though- what would happen if I then connected my iPod (to charge it, for instance) and my external drive wasn't connected? Would it just give me a message, or would it erase everything on my iPod so that I'd have to copy it all back over the next time I connect the external drive? Thanks!
