When you have a new hard drive, or when you're reinstalling Windows, the OS may ask you to format the drive. If given a choice, the two common modes are NTFS and FAT32. But what are those, and why would you choose one over the other? We break down the differences between FAT32 vs. NTFS..
What They Mean
FAT32 is the older of the two drive formats. FAT32 is the most common version of the FAT (File Allocation Table) file system created back in 1977 by Microsoft. It eventually found its way on the IBM PC's PC-DOS in 1981, and carried over to MS-DOS when that became a standalone product. FAT had been the standard format for floppy disks and hard drives all through the DOS years, and versions of Windows up to and including Windows 8.
NTFS (New Technology Files System) is the newer drive format. Microsoft introduced NTFS in 1993, as a component of the corporate-oriented Windows NT 3.1 and then Windows 2000, though it didn't become common on consumer PCs until Windows XP in 2001. Windows 7 and 8 default to NTFS format on new PCs.
Compatibility
FAT32 is read/write compatible with a majority of recent and recently obsolete operating systems, including DOS, most flavors of Windows (up to and including 8), Mac OS X, and many flavors of UNIX-descended operating systems, including Linux and FreeBSD.
NTFS, on the other hand, is fully read/write compatible with Windows from Windows NT 3.1 and Windows XP up to and including Windows 8. Mac OS X 10.3 and beyond have NFTS read capabilities, but writing to a NTFS volume requires a third party software utility like Paragon NTFS for Mac. There are other hacks and workarounds for NTFS on the Mac, but in any case NTFS is only semi-compatible with OS X. NTFS on Linux systems is spotty for both read and write operations. Look for NTFS-3G driver support on your Linux support page to see if it's built in.
