I second that as a great idea, if you've got space on your drive - you never know when it'll come in handy. you could also keep a file encryption program on it, so you don't need any extra drivers. I don't know of any of the top of my head, but I'm sure there's something out there that can be run straight off the drive to en/decrypt files
