So that was SDHC vs SD? Or was it even that? 2GB was the original SD
limit IIRC correctly, so you weren't trying to use the wrong spec. Was it
just a case of a faulty card, either through accident or design.

However, those cards were more expensive than current huge cards, so the
temptation to sell fakes would have been even greater. Many years ago I
got burned like that with a large (for the time) capacity USB stick
bought on Ebay.
