If you are working on Linux and found that a disk partition is missing or not visible in your Files browser and you want to check if that exists or not.

Apply any of the following command:

lsblk -f

mount a partition

sudo fdisk -l


If you want to mount a partition named /dev/sda4 to a folder in somewhere like /home/userasha/backup, then first create a folder named “backup” into /home/userasha location then give following command:

sudo mount /dev/sda4 /home/userasha/backup
