It is usual that at a certain moment we lend a USB to another person, so that they can download some documents that have been stored in it. Or do it with an SD card, so you can have the photos on it. In these cases, what we want is for that person to copy the files, but nothing else. We don't want you to be able to make modifications to anything.. To do this, we have a method.
Since there is the opportunity to write-protect a USB or SD card. This means that said person will not be able to do anything regarding modifications to the device. All you can do is copy these files. So it is a system that we can pay attention to.
So this is a way to be able to share files with a certain level of protection. Prevent document changes from being made without your permission, something that has probably happened to someone on occasion. The steps to follow in this regard are very simple. This way, it won't cost you anything to add this protection to a USB or SD card.
At the same time, this is something that we can easily do in all versions of Windows. The steps are the same in all of them. Therefore that it doesn't matter if you have Windows 10 or Windows 7, which will have no problem doing this. Since the procedure has remained the same in this regard. We show you below all the steps to follow:
Add write protection on USB or SD
The first thing we are going to have to do is connect the device in question to the PC. Ya be un USB o una tarjeta SD, tenemos que insertarlo en uno de los puertos de la computadora. Cuando lo hayamos hecho, abrimos el explorador de archivos de nuestro equipo. Posteriormente debes mirar la parte izquierda del browser, en la columna que aparece en esa parte. Allí tendrás la opción de ver que sale el dispositivo que tienes conectado.
Subsequently, you have to right click with the mouse on the USB or SD memory card that you have connected to the computer. A contextual menu will appear on the screen, in which we find a series of alternatives. Of the alternatives on the screen, we have to click on Properties. So that we can have access to them.
Subsequently, the properties of this device are opened on the screen. We have a series of tabs at the top. To this end, the one that interests us is the first one that we find on the screen, what is security. Therefore, we click on it. Once inside this section, we have to click on the edit button, which we will see that is in the center of this window, below its box. So we can move on to the next step.
A new window opens, what are the unit's permissions. In it we find the opportunity to establish the permissions that we want to give to this USB or SD card. Let's see that at the bottom of this window there is a list with permissions. Next to them there are two columns, which are those of accepting and denying. We have to look for the write permission on that list. Subsequently, you must check the deny column. So this permission is not granted, which means that we are write protecting the USB.
You just have to click on accept, to save the changes.. From this dynamic, we have already protected this USB against writing. If at any given time we want to change this again, especially after having left the USB in question to someone else, we only have to uncheck the deny column.
