 Not positive, but I think it referred to the drive. My 1541 only had
 heads on one side of it. So when I used SS SD disks they were disks
 that were only able to be used on one side with the drive spinning one
 way. From the way I understood it at the time, a SS disk was one that
 had failed the second side and had been marked SS. You could punch a
 hole in the side that wasn't used and turn it over but doing so was
 frowned upon.

 Maybe correctly. Since the drive collected fuzz and dirt spinning one
 way and when you turned it over to use the 'questionable' side it would
 spin the opposite way and might mess up the head or mechanism.

 At least thos are the stories I used to hear. I did this in practice
 and never had any hardware issues, but some disks were 'bad' on the
 other side and not useable.

 Just my rememberings...
