I didn't occur to me know (because I never really thought about it), that a SS disk would just be a DS disk sold as a SS disk, perhaps simply because one side of the disk failed a QC check.

Makes sense now.  You manufacture DS disks.  If both sides are bad, bin it. If one side is bad, use the other side in a SS disk.  If both pass, its a DS disk.
Is that how it worked?

.... It said "insert disk #3", but only two will fit...
