So I have a USB drive that's formatted Fat32 and I'm really confused. I've heard that there are file size restrictions in this particular format (2GB max?) and I'm really worried about some of the data I have backed up on this drive. All my photos, for instance, in an Aperture Vault. That file alone is 20Gb of space on my disk... If Fat32 has these limits... Will it not open up if I have a catastrophe and have to restore from that vault? I mean, if there's a limit, how did I get it over there in the first place? I don't really want to format this drive in HFS+ because I'd like to be able to access them in both Windows and Leopard (and on my Xbox 360) but I'm worried that the integrity of my HD, and/or my data might be at risk the way I'm using it now.
