The output from the blkid command above can be used to identify the hard drive when adding entries to /etc/fstab.

Next you need to edit the /etc/fstab file. The lines in this file are organized as follows:

UUID={YOUR-UID}    {/path/to/mount/point}               {file-system-type}    defaults,errors=remount-ro 0       1

Unmount external disk

sudo umount /dev/sda
