Is there an old bug-report on this?
You may be the first person to encounter it. (I've never heard of it)
Of course, I don't use floppies as a rule, though I have a system or two
that have actual floppy disk drives.
I just tried mounting an empty drive on my laptop, running -current.
I see the problem.
However, after about 5 tries, it seems to give up reporting a "hard error".
Until it gives up, it seems to hog the CPU, though, making other actions
sluggish, and seems to ignore ^C attempts to break it. I.e., it seems
to be in the kernel, and nastily done (busy-waiting, maybe?).
But, it's a new one on me. I don't know if it was smarter in the past,
or if I just haven't had to deal with it because I don't do floppies
if I can avoid them. I'm intrigued enough to have a quick rummage around
the sources.
