sudo mkfs.exfat -n eData4TB /dev/sdg

(sudo mkfs.ext4 /dev/sdg for ext4)
Note exfat works for both Ubuntu and Mac and eData4T is the label name:

(base) brcao@aw2:~$ sudo mkfs.exfat -n eData4TB /dev/sdg
mkexfatfs 1.3.0
Creating... done.
Flushing... done.
File system created successfully.

Create a folder /media/brcao/eData4TB where you want to mount the new hard drive:

sudo mkdir /media/brcao/eData4TB

sudo vim /etc/fstab

Append the following line to the end of the file:

/dev/sdg        /media/brcao/eData4TB   exfat   defaults        0 0

Mount the hard drive:

sudo mount /media/brcao/eData4TB

(base) brcao@aw2:~$ sudo mount /media/brcao/eData4TB
FUSE exfat 1.3.0

Then it can be accessed by the system:

(base) brcao@aw2:~$ df -h
