When I received the card because there are fakes, I checked it and it turned out to be fake. As an EE retiree I needed to know more, so after a few days of research and testing I found that all my old (5+ year olds) SD card adapters couldn't handle the new card. Then I bought a new SmartQ C368 USB 3.0 Multicard Reader (AMAZON, of course). The cards now pass all tests and work perfectly with my Windows backups.
