Floppy discs have lasted decades longer than expected. But by now, many have started to fail. In  this talk, we’ll look at a few discs that are unreadable even with modern low-level tools such as a Greaseweazle. Can we recover corrupted or decayed data by attaching a modern oscilloscope directly to a disc drive, and what are the limits?
