OK, my question is two fold. First. I'd like to move my music collection from an external drive onto my iMac's internal drive. I use iTunes, though, and wasn't so sure what that would do to my iTunes music library. I don't want to have to delete my library and start a brand new one because I have a lot of ratings that I'd like to retain. So, how would I go about doing this without having to start a new library? Or would I even have to start a new library? Second. I'd like to partition my iMac's internal drive but I would like to do it without having to reinstall Leopard. Is there a way for me to partition it 'on the fly'? Could I just configure it all in Disk Utility or would I need to put my iMac in Target Firewire Disk mode and have another Mac partition it? And would I need to reinstall Leopard if I did either of those things or would Leopard stay intact? I'm currently running 10.5.1 with all of the latest software updates on a 20" 2.4Ghz C2D iMac. Any help would be greatly appreciated. Thanks.
