The lsblk command is capable of giving out more information about storage devices, but we are keeping our focus on formatting a device. The last column tells about the mount point. TYPE tells whether it’s a disk or partition, and you can see that block device name with numbers ‘sda1, sda2…’ are marked as partitions. RO tells whether the device is read only, such as a DVD drive or write protected Flash drive. Obviously, the SIZE column tells about usable storage space on the device. RM tells whether the device is removable, and in this example, you can see that the USB drive ‘sdb’ is a removable device. MAJ:MIN denotes the major and minor device number. are the block device names and ‘sda1’, ‘sda2’… denote the partitions on each device. In the figure above, the NAME column gives out the name of the device (it’s not consistent and can change based on which device was mounted first). As you can see, the lsblk command is showing me my SSD ‘sda’ where Linux Mint 18.1 is installed, ‘sdb’ is a USB Flash Drive, and ‘sdc’ is 1TB internal hard drive. Using ‘lsblk’ is the simplest and easiest way to find all block devices connected to your system.

How to find what is connected or plugged to your system
I prefer to use the command line, as it’s much easier and fail safe.
However, every once in a while I come across issues where it throws errors and fails to format a drive. If you happen to use Gnome, then the Disks tool is quite useful. There are many graphics tools to manage your hard drive. The article is aimed at beginners and new users of Linux. In this article, I will talk about some of the basics of storage devices on Linux.
With a tiny mistake, you may lose data or wrongly format your drive in a way that can lead to data corruption. Managing storage devices - whether they are internal hard drives, SSDs, PCIe SSDs, or external USB devices - is always a tricky task.
