So far the card seems fine. But oddly enough I can't get the Samsung microSD to SD card adapter to work in my PC. I found an older 32 GB EVO card I had bought last year and that Samsung adapter doesn't work either. I measured them with calipers and they seem to be the same size. I thought the Samsung adapter was a bit thinner, but if anything the one that works is a couple thousandths thinner.
I don't have any reason to believe the two Samsung adapters are actually fake and the ones that work most likely *are* fake. I also have some Kinston branded adapters that also won't work.
This explains why I couldn't get any of the several 1 GB microSD cards to work last year. I guess I never realized it was the adapters and not the microSD cards. They all seem to work now in the two good adapters.
I'll have to see if I can get any of the "bad" adapters to work in the rPi which I just found today. Seems I had it squirreled away in an unmarked box.
