I did this many years ago when I was a bench tech at a PC shop. It was an old Connor 40 meg drive running DOS. If I squeezed it just right, it would work. Too much? Failure, Abort/retry/ignore. Not enough? Same. So I stood there, squeezing the drive, and hitting ‘r’ for retry, over and over. It worked!
Boss walked by. “What the heck are you doing?”
“I’m milking the data out of this drive!”
