How to Format USB Drive on Linux? | 3 Methods
A USB is a practical accessory that provides a wide range of allocation and
customization choices. To utilize its potential, one must understand how it
operates. We frequently need to update a file system for better system
flexibility or erase data for any particular purpose.

We need formatting at times like this. But many people view it as a tiresome
process they don't want to encounter. So, in this article, we'll walk you
through the process of formatting your USB drive step by step. The "Discs" program
or the terminal can be used for this. So let's get started without further
ado.

Many people view USB formatting as a taxing operation. There are various
things to watch out for when it comes to windows. Linux, though, makes it
far simpler. Don't worry; once you've read this tutorial, you'll be able to
format your drive without any problems at all.



In Linux Format USB Drive Can Be Done in 3 Ways:
Luckily, formatting a flash drive is simple and quick using the 3 techniques
listed below:

Using the Terminal
Using Disk Utility
Using the GParted tool


With USB devices, file sharing between platforms is really simple. They can
also be used to create live Linux installation mediums. Using dedicated
flash drives is simple because they are plug-and-play devices. However,
there may be times when you want to format your USB drive under Linux.

In linux format USB is required (for instance, while changing the file
system or deleting data) on occasion. However, a lot of Linux users are
reluctant to begin the formatting procedure because they believe it will be
difficult or take a long time.



Format USB Drive with the Linux Terminal
Formatting a USB device is easy if you already know about the terminal. Many
command-line tools can be used for this process, as may be seen in the list
below.


Locate the USB Drive
Before you can format your USB drive, you must locate the appropriate
device. Use the lsblk command to find out what your drive's device name is.
After attaching your USB to the desired port, give the command:
lsblk

The essential device can be determined by looking at the size. It should be
something along the lines of /dev/sdX , where X is one of a, b, c, or
something else.

Remove the USB
The USB partition should be removed than. As the remainder of this tutorial,
we'll assume that the device's name is /dev/sdb and that its disc partition
is /dev/sdb1.
	sudo umount /dev/sdb1

With the umount command, the device is unmounted. Now that you're ready,
format the USB.


Format the USB Drive
By dismounting the device, you can continue to format it with a new file
system. Make cautious to backup any crucial files because you will lose
access to them after completing this step.
	sudo mkfs.vfat -F 32 /dev/sdb1

With the aforementioned command, you can format your USB drive using the
popular FAT32 file system. However, you can choose an alternative file system
like NTFS or exFAT.

To give your gadget a name, use the -n option.
sudo mkfs.vfat -F 32 -n 'live-usb' /dev/sdb1



Format USB Drive with Disks Utility
In linux format USB can be done using disks. Most of popular Linux
distributions come pre-installed with a disc manager. For instance, Ubuntu
comes with the GNOME Disc Utility—Disks. Linux users may easily format USB
drives with this utility. To format yours, follow the instructions below.


Start Disks
To find the program, In the search menu, enter "discs". In order to start the
software, click Discs.


Locate the USB Drive
	

	available devices by discs

A list of all available storage devices, including HDDs and USBs, will be
provided by discs. Connect your USB if you haven't previously, then look for
the drive in the list of linked devices. Click on the USB to choose it.


Format the USB Drive
After selecting the appropriate device, you can start formatting. Selecting
the Gear icon in the bottom menu will bring up the Format Partition option.
	
	
	format appropriate usb drive

The dialogue box that displays allows you to name the USB drive, select the
partition type, and erase any previously saved data. The best partition type
is FAT since it works with all devices and operating systems. You can select
any alternative type if you'd like.
	
	
	name usb drive and details

Next, move on to the prompt that displays a data loss warning by clicking
Next. To finish formatting your USB in Linux, click Format.

You can replace Discs with the KDE Partition Manager program if you're using
KDE rather than GNOME. There shouldn't be any problems because the steps are
quite identical.

disc management program that makes it simpler for Linux users to format USB
devices. Utilizing one of the commands listed below, you may install it on
