I'm trying to mount my two harddrives (sdb and sdc) on Ubuntu 18.04

    $ sudo fdisk -l

'sudo mount /dev/sdb1 /media' doesn't seem to work and gives me the error '/dev/sdb1 is not a block device.'. How do I mount it?

Welcome to the StackExchange!

First of all, you would need to format or add at least one partition to the newly added hard drives.

This can be accomplished by either using the terminal with fdisk type this to select the first hard drive you mentioned:

$ fdisk /dev/sdb

Type ‘n’ to create a new partition.

Specify where you would like the partition to end and start. You can set the number of MB of the partition instead of the end cylinder. For example: +1000M

Type ‘p’ to view the partition, and type ‘w’ to save the partition.

Run the command:

$ partprobe

This will allow your OS to detect the new partition table. If it still does not detect the partition table, you might need a reboot.

Then format the newly created partition with mke2fs this is used to create an ext2, ext3, or ext4 filesystem, usually in a disk partition. See the mke2fs(8) manual page for more details.

# mkfs.ext4 -L myHDD /dev/sdb1

Then create a directory to mount the partition to:

# mkdir -p /mnt/media

then mount(8) the newly created partition to the newly created directory:

# mount /dev/sdb1 /mnt/media

then run the command lsblk(8):

$ lsblk -f

NAME    FSTYPE   LABEL                UUID                          MOUNTPOINT

sda

└─sdb1 ext4     myHDD     56adc99b-a61e-46af-aab7-a6d07e504652   /mnt/media

or you could use a GUI like gparted which basically does all of the above with a couple of mouse clicks if you're not comfortable using the terminal.
