i want to learn about hardware copy protections of usb drive. But i have only seen that usb copy protection can be achieved in two ways: hardware level and software level. i try to understand hardware based usb copy protection.
I used to have a mini computer that had hardware protection on its OS. The device was called a Dongle and this linkwill take you to the WikiPedia article about them. But if you mean ways to protect a hard drive, I don't know about them.
thanks. i know a little about dongles. can it be possible that use a vendor id or unique id for protecting usb drive?
