OK, I have searched for this and cannot see that it's been asked before. I have an external hard drive which showed up under OSX and my XP running in VM Fusion. I wanted to transfer a file of about 5.4Gb to this, but it always failed. After reading around I understood that this was due to the 4Gb file limit under Fat32. So, I formatted the (80Gb) drive to NTFS and transferred the file no problem. Unfortunately my Xbox 360 won't recognise NTFS drives. So I thought I'd reconvert to FAT32. However it seems that this is not possible due to the 32Gb limit of Fat32. Two questions. First, how come my 80 Gbdrive was delivered preformatted to Fat32 if the limit is 32Gb? Secondly now I've partitioned an 80 Gb drive into 32Gb of FAT32 and the rest to NTFS why won't anything show up on my MAc?
