What you owe know about formatting a hard drive is that, once done, all information that was not previously backed up will be irretrievably lostSo the first step is to back up your most vital data.

Among these data we can take into account the following:

  • Documents: we mean images, videos, audios, spreadsheets, presentations and any content that you have created or saved that could be of importance in the future.
  • Downloaded programs: Saving the installation files of any program that we have downloaded from the internet is usually a great energy and time saver by not having to search for the program online again.
  • Browser information: Make sure to save the bookmarks and favorite pages stored on your computer in case it is an important page, since after formatting it is likely that you will not see it again.

One more factor to consider is the volume of all data, since this is what will determine if you can make the necessary backup in a USB memory, or if you need an external hard drive or even an account in a cloud service to store data in large quantities. While each choice is based on the circumstances, if you can choose the cloud storage service, choose itas it is the safest backup option available so far.

The innate versatility of Linux gives you access to a variety of ways to format your hard drive, then now We will explain the two methods for a safe procedure step by step.

From the command console

Command console on Linux

To be able to perform the formatting using the command terminal, the first step is to make a partition by following these steps:

  • Connect to hard drive to format and verify the connection with the command sudo fdisk –l.
  • Create the partition on the hard disk by typing the command sudo fdisk /dev/sdb , the terminal will display a list of supported parameters.
  • It is the visible list, press “P” this will show you the hard drive identifier and sector space.
  • Press “n” To create the new partition, two types of partitions that you can create will be shown: primary (p) or extended (e).
  • Select “p” to create a primary partition and assign a number from 1 to 4, depending on how many partitions you want to create. If you want to create just one, press “1”.

Once the partition is created, insert the command sudo mkfs.ext4 /dev/sdb. With this, the system will search for available partitions on the drive, as soon as you select the partitions to format and confirm, simply press “and”, then all that remains is to wait for the process to complete.

With an external tool

Gparted interface on Linux

Formatting the hard drive with a graphical interface tool is the simplest option and suitable for those who are not used to working with the command terminal.

The steps to format the hard drive using the GParted tool are as follows:

  • To open Gparted.
  • To select the hard drive.
  • Choose the partition to delete. If it is more than one, the process must be carried out as many times as necessary.
  • Once all partitions have been deleted, the graph will show a single space labeled “not assigned”
  • Confirm the changes.

Once these steps are completed, the hard disk will be ready to assign the partitions with completely new data.
