Also asked, what is MS DOS FAT 32?
If you absolutely, positively will only be working with Macs and no other system, ever: Use Mac OS Extended (Journaled). If you need to transfer files larger than 4 GB between Macs and PCs: Use exFAT. In all other cases: Use MS-DOS (FAT), aka FAT32.
Can fat32 be read on Windows?
Windows' default NTFS is read-only on OS X, not read-and-write, and Windows computers can't even read Mac-formatted HFS+ drives. FAT32 works for both OSes, but has a 4GB size limit per file, so it isn't ideal.
Can exFAT be used on Mac and PC?
Most WD Drives come formatted in the NTFS (Windows) or HFS+ (Mac) format. For a hard drive to be able to be read and written to in both a PC and Mac computer, it must be formatted to ExFAT or FAT32 file format. FAT32 has several limitations, including a 4 GB per-file limit.
