When I was in my first summer job in 1987 (paying my Dad back the money 
he used to buy me an Amiga 1000), I suddenly had access to a 'limitless' 
supply of pre-formatted HD 3.5" floppies from the office store cupboard. 
I was terribly disappointed when none of them would work reliably in the 
Amiga, though it probably saved me from getting fired for stealing. :-)

Years later I found out that I could make them work by wiping them with 
a bulk-eraser (very powerful elctro-magnet) first.
