To clear all disks, run this command: for i in /dev/sd* do wipefs -a $i done If that’s the case, change the command below to wipefs -af to force wiping even mounted disks, including the USB stick. On some distributions besides grml, you might also notice other disks listed in this output, which means they were auto mounted. You’ll see an error that this device is busy, which is fine since we don’t need to wipe the USB stick. Look for the entry matching the size of your USB stick. You can identify which disk is the USB hosting the live Linux with: df -h Take note of whether you see nvme in any of the outputs. To see what disks are connected, run (that’s an “l” for “lion”): fdisk -l You can run this command first to switch to the root account: sudo su root If you see a $ sign rather than a # on the terminal, you’re not root. Grml gives you a root command prompt by default, but other distros may not. Most of the commands below need to be run as root. Following this guide will clear everything from the disks in the system. Please use extreme caution with the commands below to avoid unintended data loss. Then plug the USB stick into the 3Node and select it as the boot device. However, some farmers report that grml won’t boot on their system.Īfter you download the live Linux iso file, burn it to a USB stick using a tool like dd or balenaEtcher. I like grml because it’s small version is only 400mb, whereas Ubuntu Server is 1.4gb. You can use a minimal live Linux distribution like grml or Ubuntu Server to boot the system to a command prompt and enter the commands below. The Linux shell commands may work on MacOS too-if you try it please let me know. I’ll explain a method that uses a live Linux distro for the job, and also link to a guide for accomplishing this within Windows.

Leave a reply here or you can contact me to ask the questions. Suggestions are always welcome. In that blog post, I have explained steps to encrypt the USB drives using LUKS. If you are trying to encrypt your USB drives using LUKS, please click here. See the following picture, and you will get all your answers. After this you will not face any error while cleaning the signature as well as while creating the partition. You just need to fire a simple command that will unmount the USB drive. Now, let’s follow some standard way rather than doing it forcefully. But we don’t have this option while creating LUKS partition. We have option to clean signatures forcefully, so we can use it. This is the same reason to get error while creating LUKS partition. Therefore when you are trying to use “wipefs” tool on it, system shows the error. When you connected your USB drive to your laptop, it gets mounted at the directory. You will get answers of all your questions when we will discuss the solution. Why we are unable to create LUKS partition? What happens when we use wipefs tool to clean signature? Why we are unable clean the signature from the device? You cannot use “–force” as there is no option to execute this command forcefully. You will face this error when you are trying to create LUKS partition. Error is as follows: Cannot format device /dev/sdb1 which is still in use. Let’s focus on the other error which occur when you are creating LUKS partition. So I have used other ways to format device. It will display message which gives you information about erased bytes.īut I don’t like to do things forcefully. It will clean the signature from the device. You can solve this problem by using the option “–force” that come along “wipefs” tool. You will face this error when you are going to use the “wipefs” tool to clean the signature from the USB drive. If you are implementing LUKS tool on your USB drive which is connected your laptop, you may face two error at the start of the implementation.Įrrors are as follows: Probing initialization failed: Device or resource busy
