Oh, not again (this has been a FAQ on this list many times...)

HD disks are different (higher coercivity) to DD/SD disks. Period. That's
why HD disks do not work reliably in DD drives.

However, it is believable that all disks are made as double-sided and the
ones that failed the tests on one side were sold as single-sided...

I don't believe in making a profit from fellow old computer enthusiasts.
On the other hand I don't want to make a loss either.

If I've got a piece of 'junk' that I don't want (which pretty much limits
it to clone PC cards...) then it will be free. If I have to buy
components, I charge for them at cost. And if I want the item then it's
not for sale at any price.
