In the day, in my work, I have a partner who has a pen, and he wants to give it a new format. But, he tried to make a new format in his laptop (Ubuntu 16.04 Unity), and with Gparted he make a ext4 format in his pen. But then, he tried to copy a file (a video) in his pen and there was a message that says he has not permissions to copy, just read in the device. I know how to quit and format his pen in his laptop, but I cannot use his pc. How can I delete all the pen and create a new format without permissions? I mean, with the app "Disks" I can but, when I connect that pen in my computer, it says that I don't have permissions except to read the files, and it's even if I'm root. (I guess because the root who create the format was my partner in his laptop, not mine of course).
Sorry if I wrote something bad, I write this so fast. Thanks!
PD: I don't think this is important, but I have Ubuntu 18.04 (Gnome).
