We show you two methods with simple steps: One to be able to encrypt a USB from BitLocker which is a function that is installed in Windows by default, and the other to be able to encrypt a USB using Mac as the operating system.

We will also show you a small list of some programs that will allow you to encrypt any USB drive, offering free and paid versions. These programs are some of the best you can find on the market.

What is USB write protection and what is it for?

When we talk about write protection we mean a kind of policy that prohibits any deletion, modification and formalization of information that we want to apply to a USB drive The causes? It may be because the user does not have full access due to few privileges or that the information to be modified is currently protected by the same USB.

For this reason the name of protection against writing, since it is called at the computer level, as that restriction to the modification, elimination or any alteration to the information. Many of the people use this type of protection to take care of their private documents or files, although there is also a large population that activates it without realizing it..

Its use is very varied, although you should know that it is a somewhat delicate function, and we will explain why later.

Why lock a USB flash drive against writing? Benefits and Advantages

According to statistics, many are the people who want to know how to remove this type of protection from their USB drive, but since you are here we will show you some benefits of enabling this type of protection, although you can use them for any other reason:

  • Prevent people outside of you from snooping around your files or documents: Many are the times that we neglect ourselves and forget our pendrive, and a person comes and grabs it. Well, with this protection that person will not be able to review, modify, or add anything to your USB stick.
  • Avoid information theft: Many are the computers programmed to steal information from any disk that is connected to it, encrypting the pendrive. Unless you grant the permissions, no virus or data stealing software will be able to access your USB.
  • Privatize your documents: In this way you can have a USB strictly for your personal use, so that no one without your consent can use it. However some people partition the drive, encrypting only half of them, to have one available to all audiences.

Note: as in everything there is a risk, and this is that If the password for encryption is lost, you may lose everything on the disk. For this reason you must take care of the password determined by you, and the one that the same system gives you as a recovery.

Steps to lock and encrypt a USB stick against writing on all devices

There are many softwares that allow us to encrypt a USB memory, but in this first method we will explain how to encrypt a USB from Windows using its default program, known as “BitLocker“, this is one tool developed by Microsoft and is very useful:

With BitLocker

This tool allows us to encrypt a USB or any hard drive, for this we only go to the folder “Team”, which we can find from the Windows menu. When we are in the indicated folder we right click on the device we want to protect, it will display a list of options which we select “Enable BitLocker” to start the process.

Then a window will appear whose name is “BitLocker Drive Encryption” which gives us two options; one to encrypt the drive with a password, and the other to encrypt the drive with a smart card.

  • In this case we select The first option. When we select it, it will allow us to establish a password and then it will require us to type the password again, in order to confirm the password that we want to establish.

  • Then we click on “Next”, and Windows will create a second password for us that can be used in the event that we forget the designated password. We can save or print this password given by Microsoft.

  • Later we will have to click on “Next” and choose between two options; one for fast encryption and one for slow, but full encryption of the USB. The virtue of the second option is that it also encrypts the data that we have deleted, although it can still be recovered. To continue we click on “Next”.

On some occasions they may require us to choose between two more options; One for one “New encryption mode”, which is for fixed units of a single device, and the other “Compatible mode”, that allows the USB to be compatible with any other operating system or other version of Windows.

  • Finally, click on “Next” and it will direct us to a window where it will ask us if we are ready to encrypt the selected drive. If we are satisfied with everything we have chosen, click on “Start encryption.” In this way, our unit will be encrypted, and the only way to modify or alter any information stored on the USB is by writing the key designated by us or the one that the system gave us as an emergency.

On macOS

This method explains how to do it if the operating system is Mac. Really in super simple:

  • First we connect the USB that we want to encrypt to the computer, after it is reflected on the desktop we right click on it.
  • Later, in the list of options that is displayed, we choose “Encrypt” to be able to enter the password with which we are going to block our USB.
