How to format a drive in exFAT so it works on both Windows and Mac

There are many file formats that Windows 10 can read and exFat is one of them. So if you are wondering if Windows 10 can read exFAT, the answer is Yes! But why does it matter? The point is that Windows 10 usually formats using NTFS and macOS uses the HFS+ file system. While NTFS might be readable in macOS, and HFS+ on Windows 10, you cannot write anything when it comes to cross-platform. They are Read-only.

I am the kind of person who needs to switch between both the OS daily. So I needed a format which is both read and write on both the systems. It is where exFAT or Extended File Allocation Table comes into the picture. If you don’t know, exFAT was created to be used on flash drives like USB or SD cards. So the question is how do you format a hard drive using exFAT? The answer is even more straightforward.

Before we go ahead, if you have anything on your drive, make sure to backup everything. After these steps, everything will be lost forever.

  1. Plug-in your drive into the computer’s USB port.
  2. Open up File Explorer and right-click on the drive.
  3. Choose Format.
  4. In the File System dropdown, choose exFAT. Possible you might get NTFS or FAT32.
  5. Click Start and close this window when finished.

Now you can plug into any OS – even Linux, and it will work in reading and write mode. You might argue why not use FAT32 which works for both the OS’s. But the problem is with the size limit. You can have a maximum of 4GB size limit per file which is not ideal. The only drawback of exFAT is that it doesn’t support Journaling, i.e., cannot keep track of file changes. Any changes you make on files on this system is permanent.

The disappointing part is that there is no way to format a drive into exFAT in macOS. You can only format a drive in exFAT through Windows. So this is best suited for hard-disk which you carry around a lot, and you have friends using different OS’s.
