I have few questions regarding Pen-drive security. 1. Is there any way to, prevent a pen-drive, to stop detecting on random system. I want to detect my pen-drive on a particular system. Please, recommend a proper solution anything with software or hardware would be helpful. 2. Can we stop a pen-drive from being formatted without proper authentication. I have tried like all the software they are good but after formatting all data is lost. Thanks in advance.
