But thinking about it, this probably wouldn't work after-the-fact for a disk
that was written using an index hole on the other side in relation to the
read/write area. We had to punch this hole prior to using the 2nd side, so
the data was written in relation to the new hole - both sides of the flippy
having the same relation between the index hole and read/write area.

But I do remember a friend removing the media completely and flipping it
over inside the jacket to read a disk on an Apple II that we had in school -
for some reason it wouldn't read the other way.
