Sometimes when you connect the second hard disk after reboot it is not automatically mounted, have to do it manually every time you turn on your computer.

A few simple steps will allow You to do automatic mounting of a hard disk or partition at boot.
First look at the IDs of the connected partitions, run this command:
/dev/sda1: UUID="1c1ed346-9d43-45ed-a8ae-99a1ae89778c" TYPE="ext4" /dev/sda5: UUID="634f0a17-b981-49a9-972f-5e56629831e5" TYPE="swap" /dev/sdb1: UUID="82b40ac2-265b-40d8-96c5-60a47478e0fa" TYPE="ext4" /dev/sdb5: UUID="f8b1807c-bb57-4be2-92e9-ebd0235597d7" TYPE="ext4"
In my example it is seen that the main drive (system) is sda, I need to mount a second hard drive sdb.
Settings partition /dev/sdb: UUID="10d4bbc7-fd2a-4aec-a263-7f31c97d85cb" , type ext4 file system, all these parameters will be used to automatically mount the disk.
For human-readable display, many systems use a canonical format using hexadecimal text with inserted hyphen characters. For example:
Before you mount the drive you need to create a mount point (folder), create a mount point will be in the media folder (you can create this folder anywhere, for example in your home directory)
sudo mkdir /media/otherdisk
,otherdisk is the mount point, You can choose any other name.
In Linux Mint (Ubuntu, ElementaryOS, Deepin, etc) there is a special /etc/fstab file, which stores settings mount the various partitions, including the root and swap, open it for editing:
sudo gedit /etc/fstab
your distribution may be a different text editor. Universal nano editor that can open text files directly in the terminal.
Add in this file entry with the parameters we need
With UUID everything is clear, we simply copied the disk ID, then specifies the path to the mount point is /media/otherdisk and the file system type is ext4. The defaults parameter consists of two numbers, the first number is 0 means it is disabled backup file system, the second number 3 means the procedure of checking the file system when the computer starts.
Save the file.
Next, mount the drive "sudo mount -a" or just restart your computer. Upon reboot, the disk will be automatically mounted.
