I still sometimes have to erase a floppy to use it, if the format
is not recognized by the computer. A standard hand held bulk eraser
is what I use. Still a somewhat time consuming process, as
it takes several passes to do it. Is there still such a thing being sold?
Ebay?

Using the computer to erase is obviously a very long chore.
