How to auto-mount hard drives in Ubuntu

List partitions and note the name and UUID of the partition you want to mount

sudo lsblk -o NAME,FSTYPE,UUID

Sample output:

NAME                      FSTYPE      UUID
sda
├─sda1                    vfat        7158-C80D
├─sda2                    ext4        639f097b-6b4e-4c93-b91e-29e219e5ddce

Create a mount point

mkdir /mnt/myDisk

Edit fstab:

sudo nano /etc/fstab

On the bottom, add a line like this for each partition you want to automount

UUID=<partition uuid> /mnt/myDisk auto nosuid,nodev,nofail,x-gvfs-show 0 0

Test the new config by this command

sudo mount -a 

There should be no errors if the config is good. Reboot your machine.
