So apparently, Macs can only read NTSF, but not write to it. Will it write to FAT32? Is there an application that will let me re-format it to FAT32 without deleting everything on it? Also, when I connected the drive to my PC and I browsed through its settings, there wasn't an option for FAT32, only NTSF. Does this mean it cannot be formatted to FAT32? Cheers.
