Setup Automount on Startup

Run blkid to get UUID of disk

/dev/sr0: UUID="2020-07-10-21-22-25-53" LABEL="VBox_GAs_6.1.12" TYPE="iso9660"
/dev/sda1: UUID="259c0e9f-c45a-4579-8b4b-ad5a86645607" TYPE="ext4" PARTUUID="75bed932-01"
/dev/sdb1: LABEL="code" UUID="0e36bdcf-377c-4a3d-b54c-3639af0766f8" TYPE="ext4" PARTUUID="0008b13e-01"
/dev/sdc1: LABEL="data" UUID="a055c10a-5028-4c38-a8f7-621b7139cd2f" TYPE="ext4" PARTUUID="00097481-01"

Make a mount point

sudo mkdir /mnt/sdb1

Edit /etc/fstab

nano /etc/fstab

Add the following line

UUID=0e36bdcf-377c-4a3d-b54c-3639af0766f8  /mnt/sdb1  ext4  defaults  0  2

Format is <file system> <mount point> <type> <options> <dump> <pass

defaults mount option allow read and write access
dump is usually zero
pass is used by fsck to determine the order of filesystem check. Root partion should be 1, swap should be 0 and other drive should be 2

# <file system>             <mount point>  <type>  <options>  <dump>  <pass>
UUID=259c0e9f-c45a-4579-8b4b-ad5a86645607 /              ext4    defaults,discard 0 1
tmpfs                                     /tmp           tmpfs   defaults,noatime,mode=1777 0 0
