Pero también hay ocasiones en que el troyano, u otra condición, daña el harvard de la USB y a la misma, no se le puede quitar la protección de lectura. Pero en #Lunux, por lo menos podremos ver su contenido, y sin temor a que se dañe, nuestro sistema.

Muchas gracias por leerme, y espero que esta información sea de ayuda para muchos de los lectores.

Greetings #Linuxeros, members of the #Linux&Softwarefree community, and greetings to the entire #Linux community at #Hive and @linux-software, welcome to a new post of #Fridaysdescritorio, January 10, 2025.

I'm still using my beloved Linux Mint 22 "Wilma", with Cinnamon desktop, the only difference I make in this presentation of the desktop today, is that this time I didn't place any application, nor did I open the terminal, since I wanted to show the photo I have as wallpaper.

When I saw that photo, it reminded me of an iconic image from the movie "The Grapes of Wrath”, but the big difference is that this image is from Venezuelan territory. Specifically of Montalban in the State of Carabobo, and it is taken by the #hive colleague, @jlinaresp, who has a group of excellent photos, which I recommend to all photography lovers to see.

When we have important data on a USB stick and we want to protect it, we can place the read-only attribute on that memory through the terminal. I know that's what #Linux does and as I commented, that's usually done to protect data. And when we do that procedure, to backup the data, we can access and view the data in the memory, but we can't modify the data, nor can we do the formatting of the memory.

• The first thing we need to do is connect the USB stick, and after connecting it, we need to find the device name using the “lsblk" command or the “fdisk -l” command

• Now that we know that our device is “/dev/sdc1. We are going to unmount the nity and to do so we use the following command "sudo umount/dev/sdc1" and when doing so it will ask us for the root key and we place it.

• Now we change the permissions and put our USB stick just for reading, with the following command, "sudo hdparm -r1/dev/sdc1”

• This is how we place our USB, with read-only permissions, and in that way you will not be able to delete, format, write, copy, anything on the USB.

• To replace the normal USB and remove the read protection, we will use the following command, "sudo hdparm -r0/dev/sdc1" and when doing so, the terminal will show the number (0) and the status of the perimsos against reading in “off”.

Points to take into account:

---

Not all USB devices support this function. So if you are going to put a device as read-only and test, make a backup of the content before doing the device formatting test. You can also try trying to copy or place files on the USB, and you will get a message like the following.

Finally, and this is for Windows users, it is very likely that a Windows user can receive a Trojan virus inside a USB and it remains in reading mode. In many cases, you can save with the drive using this method, removing the read protection by rescuing the files and removing the Trojan. See recognition of the Trojan in the image.

But there are also occasions when the Trojan, or another condition, damages the harvard of the USB and the same, the read protection cannot be removed. But in #Lunux, at least we will be able to see its content, and without fear of damage to our system.

Thank you very much for reading me, and I hope this information will be of help to many of the readers.
