> So ID numbers of all USB storage drives you've connected? Better not put sensitive data on a USB and send it to a journalist... This should definitely work for hard disks, which have a serial number in their SMART data but do standard USB flash drives have any kind of unique identifier? There's the vendor ID but that covers every single instance of that model of device. Or is there some kind of identifier at the filesystem level?
