I remember myself copying all cards in a fully filled large crate (like
the ones you use when moving to another house) to just one 360 Kb floppy
disk.
The cards are more persistent though - you could still somehow deal with
them. With floppies, not a chance.

They were all caused by the operator loading a particular deck of cards
upside down. After three crashes he realised his mistake, and didn't do it
again. What was the probability of that happening?)
How many of the XSL list have ever handled a deck of (computer/Hollerith)
cards? Some of us are showing our age....
