I would advise that you do. Ive had Windows formatted iPods basically lose all data when being plugged into a Mac. But I think when you do so, youll lose everything thats on your iPod. If you already have it all on your computer, its not a big deal. Otherwise youre gonna want to get one of the many freeware programs to back it up. Personally, I like iPodDisk
. It lets you browse through all the artists and albums on your iPod and copy them to another source(probably your hard drive). You need MacFuse
for it to work. THeres another program, iPod->Folder
that copies everything, instead of you picking and choosing what gets copied. Its an older program, so Im dont know if it works properly on Leopard.
