Unfortunately, it isn’t any good for storing movies and other large files: FAT32 has a size limit of 4 GB per file, so your files have to be small. FAT32 was introduced in Windows 95 in 1997, but it remains useful because nearly every system can use it.

A drive formatted this way will not mount on a Windows computer without additional software.

Non-Linux computers can use four main file systems: NTFS, HFS+, FAT32, and exFAT. If you use a Mac, the likelihood that you’ll have to reformat the drive is higher. If you use Windows, chances are good that you won’t need to reformat your external hard drive-unless you buy it secondhand, or you plan on switching between operating systems, your drive should come ready to use. If you buy an external drive-such as one of our recommended desktop hard drives, portable hard 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, most drives come preformatted for Windows out of the box.
