in spite of the fact that this discussion is interesting, educational, and
helpful, i think the *real interesting* question was the one originally
asked: is it true that computer X uses one side of a SS disk while computer
brand Y uses the other? as originally stated, this would mean every SS
disk *IS* really certified on both sides and we can all save at least 30
to 50% by buying SS certified disks (which would essentially give you
DS certified disks). 

i think computer "X" was a mac and computer "Y" was probably ibm/atari/...

how 'bout it...does anybody know for sure?

-bill

(it seems unlikely since the certification process does cost something
and would thus have to be done on both sides of every disk produced)
(still, i would not put it past this industry to do something like that...)
