My Dell Vostro 3491 came with 1TB HDD and 256 SSD. Ubuntu was installed on the SSD and I can use the drive for storing and accessing files. But I am unable to access the HDD.
From the disk utilities, it seems my HDD is on standby (displaying ZZZ).
sudo fdisk -l I found my HDD is marked as
/dev/sda and no partitions.
I tried mounting it using
sudo /mount /dev/sda /media/HDD but getting an error
mount: wrong fs type, bad option, bad superblock on /dev/sda, missing codepage or helper program, or other error.
What is the actual problem and how to solve it?
Do I need to create partition of /dev/sda ? Why?
