Download the following tools using your package manager, for Debian/Ubuntu (in case you are using a very streamlined version):
sudo apt install parted e2fsprogs
parted: "is a program to manipulate disk partitions. It supports multiple partition table formats, including MS-DOS and GPT. It is useful for creating space for new operating systems, reorganis‐ ing disk usage, and copying data to new hard disks." (from
mkfs.ext4: Allows creation of Ext4 partitions (like a formatting tool)
df: Report disk space usage
sudo parted -l
The output will be similar to:

Note the Disk names, they might be
/dev/nvme0n1 or something like
/dev/sda, read more about devices at
Open parted pointing to the disk you will edit.
sudo parted /dev/sdb
Warning Make sure you are pointing to the correct device, otherwise you might lose data forever.

You can use
% values for start and end.
The command is quite simple, not much to change around:
sudo mkfs.ext4 /dev/sdb1
You should be able to mount at any empty directory, for this example we will mount at
sudo mkdir /mnt/sdb1 sudo mount /dev/sdb1 /mnt/sdb1
fstabto mount it every time you boot
Add the mount to your
fstab file, make sure to point to the proper mount folder:
sudo echo /dev/sdb1 /mnt/sdb1 ext4 defaults 0 0 >>/etc/fstab
You can restart your and you should keep seeing the disk available.
