Add an entry for the new disk using name or UUID

/dev/sdd1 /media/disk04/ ext4 defaults   0       2

Fstab File Configuration

Enable or disable backing up of the device/partition (the command dump). This field is usually set to 0, which disables it. Controls the order in which fsck checks the device/partition for errors at boot time. The root device should be 1. Other partitions should be 2, or 0 to disable checking.

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

Moun the new /etc/fstab entry.

sudo mount -a

NOTE: If bump into error mount: mount point /media/disk04/ does not exist, create the directory sudo mkdir /media/disk04.

You might want to create a symbolic link to point to this new disk.

cd /sudo ln -s /media/disk04 datacd /data

You might want to rename disk volume name.

NOTE: Restart to test if the disk is auto mounted.
