How to access unallocated internal HDD on Ubuntu 16.04?

  • 772

I recently did a fresh install of 16.04 on the solid state drive, leaving a 1.8 TB unallocated partition on the internal HDD.

Somehow I can't access this partition on /dev/sda/ and also can't mount it:

sudo mount /dev/sda /media/sda/

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

sudo fdisk -l

Gparted shows /dev/sda/ as unallocated space.

Do I have to perform some type of disk repair? Or should I just allocate that space using Gparted?

mount gparted hard-drive 16.04

    You can't mount an empty disk, but only filesystems. Therefore you have to create a partition (/dev/sda1) on /dev/sda, make a filesystem in the partition and mount the partition /dev/sda1.

    So use gparted to create a partition /dev/sda1, possibly covering the complete disk /dev/sda. Then sudo mkfs -t ext4 /dev/sda1 and sudo mount /dev/sda1 <your_mountpoint>.
