Sheila wasn't the first.
I was working for a market research tabulation house years ago. One of the major functions of the company was keypunching data onto floppy disks so that we hacks could tabulate it. One of the keypunchers called me and said that she couldn't get her data onto a disk whatever she did. Of course, she had inserted the disk into the space between the two floppy drives in her computer. When I opened it up, there were four or five disks similarly placed. How we laughed.
