"It doesn't need to be inserted into a system to read it. I just need to take it off and open the interface; didn't want to do it without your permission though in case you thought I was going for a weapon or something." And no, he was not about to tell the User that a disc could be a weapon, even if he had no intention of using it as such. That would just be asking for trouble.
