Many years ago (back when 5.25" floppies were still fairly common) one of the secretaries where I worked came to me one day and said, "Can you help me? The computer ate my disk and I really need this document I was working on."
Thinking she meant that the disk was unreadable, I went over to her desk see if I could help her recover her file. I noted that there was no disk in the drive, and asked her to give it to me. "No, you don't understand!", she replied. "I don't have the disk any more. When I said the computer ate my disk, I REALLY meant it ATE my disk. I put the disk in, and when I tried to open the file, the disk was GONE!"
Well this was certainly a new one.
My first thought was that she'd lost her mind...
After a few moments of head-scratching, I noticed that there was a small gap between the floppy drive itself, and the front bezel of the computer case. The gap was just barely wide enough to slip a 5.25" floppy into. Aha!
So I grabbed a screwdriver and popped the case open. Sitting in a stack at the bottom of the case, on a rather thick carpet of dust bunnies, was not one, but several
floppy disks. Apparently her computer had quite an appetite!
I blew the dust off her disk and handed it back to her, warning her that she should copy her files to a fresh disk ASAP since the dust which managed to get inside was probably going to destroy it in fairly short order.
I then went and checked the front bezels of all of the systems in the office, and covered any gaps large enough to shove a 5.25" disk into with Scotch tape.
