NTFS is native to Windows, and most hard drives are preformatted for this file system. If you plan to use your drive for File History backups on a Windows computer, and you use only Windows, stick to NTFS (New Technology File System).So how do those five file systems differ, and which one is right for you? Non-Linux computers can use five main file systems: NTFS, HFS+, APFS, exFAT, and FAT32. If you use a Mac, the likelihood that you’ll have to reformat the drive is higher. But if you buy a drive secondhand or if you plan to switch between operating systems, you may still need to reformat it for use on Windows.

If you buy an external drive-such as one of our recommended portable or desktop hard drives, portable solid-state drives, or USB 3.0 flash drives-you may need to reformat it to work with your operating system of choice, since different operating systems use different file systems to process data.Īlthough it’s true that any drive is compatible with both Windows and macOS once it’s formatted properly, most drives come preformatted for Windows out of the box.
