So, you’ve bought a shiny new hard drive and would like to format it and use it on your headless Linux server. For this guide, we’ll be partitioning it as a GPT partition to support sizes over 2TB, and formatting it as ext4.

Find device id (/dev/sdc, etc):

lsblk

Edit the drive, using fdisk in GPT mode with:

sudo gdisk /dev/sdc
d
n
[enter] x5
w

Make a partition:

sudo mkfs.ext4 /dev/sdc1

Verify everything formatted correctly:

lsblk --fs /dev/sdc1

Find the drives new UUID:

blkid /dev/sdc1

Lastly, add a mountpoint to /etc/fstab:

UUID=00000000-0000-0000-0000-000000000000 /mnt/mount-point  ext4 defaults 0 0
