How to List All Connected Disks in Ubuntu (CLI & GUI Guide)

In Ubuntu you can list all attached storage devices—including SSDs, HDDs, USB sticks, and CD/DVD drives—using several command‑line utilities.

Using lsblk

The basic command prints a tree of block devices: $ sudo lsblk By default it also shows loop devices created by snap packages. To hide them, add the -e7 option (7 is the major number for loop devices): $ sudo lsblk -e7 You can further exclude CD/DVD devices with -e11: $ sudo lsblk -e7 -e11 To display vendor and model information, use the --scsi flag:

$ sudo lsblk --scsi

Using fdisk

fdisk -l

lists every disk, its total size, partitions, and partition sizes: $ sudo fdisk -l If you know a device name (e.g., sdb), you can query that specific disk: $ sudo fdisk -l /dev/sdb Multiple devices can be inspected by listing their paths one after another:

$ sudo fdisk -l /dev/sda /dev/sdb

Using parted

The parted utility provides similar output without the noisy loop devices. Install it first if it is missing: $ sudo apt install parted -y Then list all disks:

$ sudo parted -l

Graphical tools

If you prefer a GUI, Ubuntu ships with the GNOME Disks application, which shows each storage device, its size, partitions, and detailed information when you select a disk from the left pane.

Another graphical option is GParted. Install it with: $ sudo apt install gparted -y After launching GParted (you may need to authenticate), use the drop‑down menu in the upper‑right to choose a disk; the partition layout will be displayed.

All of these methods allow you to quickly identify every storage device connected to your Ubuntu machine, filter out unwanted loop devices, and obtain vendor/model details when needed.
