I've been lurking at this thread for awhile...
If the OP meant that bulk erase was needed to render the floppies
disposable with security, then mechanical destruction is certainly the
only reliable way.
If the OP only wanted to re-use the floppies himself, what's wrong
with simply "delete *.*" ??
If he meant to distribute erased floppies for others to re-use, but
with security, there exists software which will write randomized data
over the existing data.

I love to cook with wine. Sometimes I even put it in the food.
