You have to choose between two kinds of drives-HDDs and SSDs-as well as the interface (USB or Thunderbolt). If you already have data stored on the drive, back that data up elsewhere, reformat the drive, and then put your data back on the drive.Buying a hard drive can seem harder than it should be, though. Reformatting will delete all the data stored on the drive, so if you need to reformat, do so as soon as you buy the drive. Now that you’ve figured out those differences, it’s time to reformat your hard drive.

It’s possible, but tricky, to change the size of a partition later on in Windows and macOS we recommend backing up the data on your drive before attempting the task, since it’s possible to wipe your drive doing this. Make sure to leave plenty of room for future backups on both partitions. Now your computer will see your single drive as multiple, smaller drives. First, partition the drive using Disk Utility with macOS, and (using our walkthrough below) format one part as HFS+ and the other as FAT32 then, plug the drive into Windows and reformat the FAT32 portion as NTFS.

exFAT works on both macOS and Windows, and it doesn’t have the file size limit that FAT32 does, so you’ll be able to back up movies and other large files.

If you need to transfer files larger than 4 GB between Mac and Windows computers, exFAT (extended File Allocation Table) is the best option, although it doesn’t work with File History or Time Machine.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.

#REFORMAT A SEAGATE EXTERNAL HARD DRIVE FOR USE IN PC AND MAC PORTABLE#
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.
