My question is can I share one external Hard drive with my boot camp partition of Vista and OS X. What I want is for all my music to load up on both OS's so that when i save a playlist in OS X it will be there in Vista and vice versa. Right now I have my Lacie 250 GB formatted as a FAT32. I just think its a pain for me to re add my music everytime i get something new, but mostly i want it to save my playlists so that when i boot up in vista or mac i'll have the same playlists without having to create 2 different playlists. I hope my question makes some sense, I've done some research on this site and all i can find is how to move my PC itunes to Mac, but i just want to share my external HD with both OS's and keep my playlists after booting. Thank you in advance
