I have a couple of disks one 400gb one 2 TB. I formatted them in disk utility as exFat as i need to move between mac and PC.
whenever I take them to a pc it can't read them and windows asks to format them. It's windows 7 and it happens on a couple of computers so i know it's not an issue with a specific computer. So I format them on PC and both PC and Mac can read them. is there a bug in Mc OSX that causes them to not format properly? given that exfat is a microsoft format I wouldn't have thought there would be a problem.
