Back in the 80's and early 90's, my mother used to work as a bookkeeper
in an athletic club. She's not a computer expert but, along with her
normal duties, was responsible for the daily running and backup of their
PC/AT system containing the club's membership records. Back then
they did backups on 5 1/4 floppies. While not a super super reliable
media solution, the failure rate on their disks was much higher than you
would expect. I lived in another city at the time and recommended they
clean the drive and buy some high-quality media. They did both and
still continued to have a high failure rate. Mom was working late one
evening when the housekeeper came in and proceeded to tidy up the office.
At one point she moved over to the computer station, opened up the cabinet,
and pulled out a box of floppy disks. When Mom asked what she was doing
she responded, "Oh, these little paper jackets make the best dustpans".
Yep, she would remove the disk, sweep dust into the jacket, dump out the dust
and replace the disk.
