I've heard both yes and no, and need to know which is correct! Right now I have a MacBook with a 15GB FAT32 partition for Windows XP and its worked out very well for me. I use Windows occasionally, and when I have I haven't had any problems. It's also been really convenient to be able to read and write to my Windows folders while in OS X... I understand I'd lose that ability if I use NTFS, is that right? So, I'm lucky enough to be getting the new MacBook Pro very soon for my birthday ( !!!) and I'd like to install Vista on a ~25GB FAT32 partition. Is this do-able? I heard about some program called MacFuse to give access to writing on an NTFS drive in OS X, and allow you to change the icon, name, etc, but it looks really complicated. I'm computer savvy but I haven't learned how to use the Terminal stuff yet and command line stuff, that's just way over my head. Help? Thanks in advance.
