When buying pre-built Wintel computers (my latest is about 10 years old), I used to insist on them having a standard 1.44 Mb floppy drive. This used to puzzle salesmen - but please them, because of the extra £30 or so they could charge.
Apart from recovering data on my own, old floppies, I was able to rescue data several times from the computers that kids in my wife's school had wrecked (those machines were even older than mine, but they all had floppy drives).
I did this simply by cutting a DOS recovery floppy on my machine, booting the sick school computer from it, navigating to the school's important folders by using the command line, copying the data to another floppy and making myself a hero!
