Before continuing with the ways to perform an encryption, it is important that you know that this it will mean an extra level in security, but also in complexity. Consequently, the speed and ease that you had to access your data will be slowed down.

Further, you should know that, like all passwords, forgetting them can be a headache. Thus, it is convenient to keep them somewhere safe. However, in the case of Windows, it offers the possibility of saving a recovery key in your Microsoft account. If you forget the password and it is not possible to recover it, the only way to reuse the encrypted drive will be formatting.

Taking into account the previous recommendations, we can now continue with the most important. Encryption of discs. They can be internal, magnetic or solid state or also external like removable memories or pen drives.

In addition, it is possible to add this layer of security in any operating system, using the following methods:

On windows

  • This SO has an integrated tool (in most cases) call BitLocker with which, it will only be enough to enter “This team”.
  • There you will find all the available units. Once you’ve chosen which album to start with, press the right button mouse over it.
  • In the pop-up menu, press “Enable BitLocker.” You must be or have administrator permissions.
  • A window will open with two alternatives. The first will use a password generated by you to enable the selected unit. To do this you must write and repeat the same password.
  • Press “Next”.
  • At that time the system will offer you the recovery method through the Microsoft account.
  • The next window will ask you how much space on the drive you want to encrypt. The first option will do it only on the disk space used (which will be easier at the time of use). The second will do it throughout the unit, including data that may have been deleted. Use the latter if you have been using the equipment for a long time. Once you’ve made up your mind. Press “Next”.
  • Once this is done, in the next window you must choose the encryption mode to use. These two alternatives correspond to whether it is an internal drive such as magnetic or solid-state hard drives. The second option “Compatible Mode” is dedicated to removable drives capable of being used on other computers with the same operating system. Press “Next” once again.
  • In this last window, all the options you have just chosen will be displayed. Check that they are correct and press the button “Start encryption.”

On macOS

In the event that you have a Mac computer, the process becomes even simpler:

  • Connect the unit formatted.
  • Press the secondary click on the inserted disk.
  • In the drop down menu, choose “Encrypt”.
  • Write the password you want to use.

On linux

As with Mac, the method on Linux is pretty straightforward:

  • Right click on the selected unit.
  • Press the option “Format volume”.
  • In the formatting window, in the section “Kind”, choose “Encryption, compatible with Linux systems”.
  • Write the password and your confirmation and press “Format”.
