I'm sure there are a whole bunch of other variables at work, including (but, of course, not limited to):
1) Phase of the moon (i.e., just luck)
2) User error (a big one - caught me, for example, when I forgot to "sync" before removing the card)
3) card reader/writer dynamics. I.e., some card readers won't work with any card, some might work with card brand X on day Y, but not under other combinations, etc, etc.
I used standard Unix/Linux/Mac OS X procedure with command dd. It can happen, the system would not take all cards. It is not so new for me. I remember similar thing on Nokia 3650, not every MMC card worked correctly with this smartphone. User references there were very helpful.
There's no implication that you're a dummy. As I said, it caught me, too. I'm pretty sure that the first time I wrote the RISCOS image to the card, I forgot to run "sync" before removing the card. It can happen to anybody. FWIW, I've never had a problem writing a Linux image (knock wood, and all that), so I think there is something to what people are saying that, for whatever reason(s), the RISCOS image is more prone to this sort of problem. And, of course, it doesn't help that the thing boots and looks more or less normal (after you hit Cancel - to get past the error screen).
As I said in my first sentence, I just don't think it is a good idea to think that there is going to be a good correlation between experiential success and the brand name stamped on the card. As I'm sure you are aware, a lot of the time, there isn't really any difference from brand to brand; they all come from the same source(s) and each manufacturer just stamps their name onto it before offering it for sale.
And some folks need to stop being fanboys and see the forest behind the trees.
