Re: A mistake is one thing...
Been there, seen that. Quietly recovered floppies with PC Tools unformat and carried on.
Actually there was more to it. This person wasn't a misanthrope, but an engineer who had recently read about new class of "CMOS viruses" and was clearly afraid of them.
Others tried to explain him that common RTC chips had only about 70 bytes of CMOS memory. Furthermore, as the BIOS never tried to execute code from it, there was simply no way to use RTC as an attack vector. Yes, there were some viruses around which wiped the RTC CMOS memory, but that wasn't quite the same thing as propagating from there.
He, as a supreme engineer, obviously knew better and proceeded to format all floppies in sight. Which we quickly recovered once he had left the area.
Later he went on to become a fully blown PHB.
And 25 years later, with the advent of UEFI, flash-based viruses became possible.
