Just a thought, could it be an old external ZIP disc drive? Do you have removable discs which look like a floppy disc but slightly thicker? I have one of these which I used before CD burners became popular. It connected with a short cable to the parallel port on the computer (the one printers were connected to). You could get 100mb on each removable disc.
If it is a parallel port ZIP drive, I have the driver software for it which allows Windows XP to communicate with it.
