For a lot of operations on the Linux platform, you’ll want to know details about your hard drive. Sadly, most newbie Linux customers are unaware of how to find hard drive info on Linux. Because of this, many they into issues when operating superior operations like formatting, shifting recordsdata round, and so forth.
On this information, we’re going to cowl how one can rapidly find details about your hard drive. We’ll go over how to uncover the drive label, partition info, UUID info and extra!
Hard drive label
On Addictivetips, I reference the LSBLK device quite a bit in my Linux tutorials. The explanation I discuss it a lot is that it’s extremely helpful for day-to-day operations on Linux, particularly with issues which have to do with hard drives and different detachable information storage gadgets on the platform.
Lsblk isn’t a program you’ll ever want to set up. It’s a core utility on all Linux distributions and is meant for fundamental diagnostic functions. Moreover, the Lsblk device doesn’t require a root account and even “sudo” entry. Not requiring root implies that even for those who’re utilizing Linux on a PC with no means to enter system-level instructions simply, you’ll nonetheless have the ability to rapidly and simply view the knowledge you want.
To make use of Lsblk with its major perform, launch a terminal window. Not sure about how to find the terminal on your Linux PC? Press Ctrl + Shift + T on the keyboard. Alternatively, you should utilize the Ctrl + Alt + T keyboard mixture to open a window as properly.
When the terminal window is open, run the command under.
lsblk
After operating the lsblk command in a terminal, you’ll see a tree-like construction. This construction exhibits you many columns, akin to NAME, MAJ: MI, RM, SIZE, RO, TYPE, and MOUNTPOINT.
The entire names within the tree checklist are vital, and you should utilize them to decide details about your storage gadgets. Nevertheless, the one factor that issues whenever you’re making an attempt to work out a hard drive label is the “NAME” column.
For instance, I’ve a number of hard drives plugged in, and I want to find the title of my 931 GB hard drive. So, to find the proper label for my traditional I’d do the next.
Step 1: go to the “SIZE” column and search for the hard drive that’s 931.5G.
Step 2: transfer on from the “SIZE” column backward and make my means to “NAME” on that very same line. The “NAME” space will present me the 931.5 GB drive’s label is/dev/sda.
Find partition names
One other use of the Lsblk command is its means to present the person partition info. It really works loads like viewing gadget names. To do it, execute the lsblk command like traditional.
lsblk
As soon as the command prints the info out on display screen, find the drive you’d like to find partition info for. Then, scroll down and take a look at the tree diagram beneath “NAME.”
Within the tree diagram, Lsblk will present you traces pointing to every of the partitions. Every partition’s title is denoted by a quantity. For instance, beneath /dev/sda (the 931.5 GB drive used within the instance) we see two partitions. Their names are /dev/sda1 and /dev/sda2.
Find UUID info
Should you’re manually establishing a hard drive on your Linux system, you’ll want to add an entry within the /and so forth/fstab file. Normally, establishing a drive requires particular info, referred to as a UUID (universally distinctive identifier).
There are just a few methods to find the UUID info for a hard drive on Linux, however by far the quickest and easiest method is by as soon as once more utilizing the Lsblk device with the -f swap.
Be aware: it’s possible you’ll want to use sudo to entry the UUID info with Lsblk, as some Linux OSes disable the power to view it as a daily person.
To entry your UUID info, run:
lsblk -f
Or, in case your system disables viewing UUID info on drives as a daily person, do:
sudo lsblk -f
When the command output finishes, you’ll see the Lsblk device print out drive info because it normally does, with a brand new “UUID” column.
Save UUID info
Want to save the UUID info for later? Within the terminal window, enter the next command.
Be aware: the command written out under is an instance. Ensure to exchange the X with the UUID code output that seems whenever you run the lsblk -f command in terminal.
echo "X" >> ~/my-uuid.txt
View the saved UUID textual content file at any time within the terminal by utilizing the cat device.
cat ~/my-uuid.txt
Or, for those who’re not a fan of Cat, think about opening it up within the Nano textual content editor for a greater viewing expertise.
nano ~/my-uuid.txt
