How to wipe hard drive in Manjaro using commands

The terminal in Linux-based systems is a key to effectively exercising the functionality of a specific distribution. Manjaro does provide an extensive list of commands that can be used to perform several kinds of operations. Starting from installation, configuration, or removal of any program. Let’s dig into the commands that can assist using wiping the hard drive.

dd command : The dd command is a Unix utility that can perform multiple operations on Unix-like operating systems. The primary purpose of this command is to copy and write the data on a disk. The command written below will overwrite zeros to the sda1 disk.

The command provided below contains the following keywords that assist in several operations like:

if= : Reads data
of= : Writes data
$ sudo dd if=/dev/zero of=/dev/sda1

It is recommended to execute the following to get the space occupied by characters fetched from /dev/urandom. This process is quite efficient in making the drive secure as compared to appending zero’s and one’s.

$ sudo dd if=/dev/urandom of=/dev/sda1

Note : The sda1 used in the above commands refers to the storage  that is undergoing the wipe process. As the hard drives in Linux-based systems are identified as dev/sda, dev/sdb, dev/sdc.

shred command : The shred command in Linux-based systems is another important command-line utility to wipe your drive. These zeros and ones are passed to wipe your hard drive.

For instance, the shred command written below will perform three numbers of passes which is default.

$ sudo shred -vf /dev/sda1

To set the number of passes, the command is used with the -n flag. For example, if we need to perform two passes, the following command will assist us.

$ sudo shred -n 2 -vf /dev/sda1

wipe command : The wipe command is a multipurpose command-line utility of Linux-based systems. It can be used to remove a single file/directory and it can be used to wipe a hard disk as well. For instance, the command provided below wipes(one time) the sdb drive.

$ sudo wipe -p1 /dev/sdb

Note : If you cannot access the wipe command, you can install it using the command written below.

$ sudo pacman -S wipe
