Assuming that you have already installed the fuse-exfat and exfat-utils packages that are necessary to access exFAT in Linux:
Plug in your external hard disk. Open a terminal and type This will list down all the hard disks and partitions in your computer. Record down the id that correspond to the partition in your external hard disk.
Next, run the command: Replace “LABEL” with the label for your external hard disk and “/dev/sdXn” with the partition id that you recorded earlier.
That’s it. Optionally, you can run a “fsck” check to make sure the formatting is done properly.
