How do I access a disk that does not appear in my file and folder program?

Question

I recently started using a notebook that has Ubuntu 16.04 LTS

I know this machine has 1TB of storage, but when I open the program to view files and folders it has a total capacity of only 212.6 GB

I imagine then that the 1TB disk is not ready for use. So at the terminal I typed a command to list drives in order to identify partitions

sudo lsblk -o model,name,size,fstype,label,mountpoint

MODEL            NAME     SIZE FSTYPE LABEL  MOUNTPOINT
ADATA SU810NS38  sdb    238,5G               
                 ├─sdb4  31,4G swap          [SWAP]
                 ├─sdb2     5G vfat   OS     
                 ├─sdb3 201,3G ext4   UBUNTU /
                 └─sdb1   750M vfat   ESP    /boot/efi
WDC WD10SPZX-75Z sda    931,5G

As I understand it is on disk "sda" which is the size of 1TB or close to it

Please, what I want to know is how can I access this disk? How to view and write files to it?

I first tried to create a directory

sudo su
mkdir /mnt/mydrive

Then mount the disk for use

mount /dev/sdba /mnt/mydrive

But this error appeared:

mount /dev/sda /mnt/mydrive
mount: wrong fs type, bad option, bad superblock on /dev/sda,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.
