@mcscx I vaguely remember some DOS tool that literally showed you a counter for each read - up to the default maximum of 5 - on floppies this was quite remarkable, you could see it "aging". What was even more remarkable was that as it was getting "slower" a very large percentage of rreads needed 3 or 4 tries - it's pretty scary to see that! Of course by now I've forgotten which tool that was...
