Or was it even that? 2GB was the original SD > limit IIRC correctly, You don't iirc correctly :-) but it was the limit for cards that were manufactured, for the most part. By the time 4GB cards became common, the SDHC spec was out, and most (all?) 4GB cards were SDHC. Right pain if your device had an SD reader, because they couldn't read SDHC cards :-( You could stick an old SD card in a new SDHC reader, but not the other way round. That's why nearly all cards nowadays are 32GB min - that's the smallest SDXC size. > so you weren't trying to use the wrong spec.

And it was something along the lines of the smallest cards available were larger than the max capacity of the camera I wanted it for (that camera might actually still be in use ... :-) > > However, those cards were more expensive than current huge cards, so the > temptation to sell fakes would have been even greater.
