Hello

I have a 128MB thumb drive and was wondering if I could use it as a security feature. Meaning I dont want people being able to access my computer without the thumb drive being plugged into the USB port. I know there are keys like this out there but I dont want to purchase another drive.

Google didnt offer me any solutions, and I remember reading about being able to do this but cant find the article in any of my old computer mags. Boy, I miss screen savers on Techtv oh sorry G4.
