I have just installed a Data-doubler from OWC (will refer to it as optibay for ease-of-reading) and I've installed OSX and Windows on the SSD. Now I've got a 750HDD that I want to put all my iTunes / games / files on. Problem; I want to use the hard-drive in both Windows and Mac. I know there's the obvious FAT32, but that can't house files bigger than 4GB. I have heaps of .ISO games that I've ripped from disks over the years, and most are bigger than 4GB! Some as big as 10. What would you guys recommend? Thanks so much.
