Are you certain that the SD cards are genuine? There are lots of fake
large-capacity SD cards floating around. For instance, I ordered some
supposedly 16GB cards that would fail if you tried to write more than
about 3.5 GB. When I tried to format them, they became 4 GB cards,
because it turned out they were 4GB cards incorrectly formatted and
intentionally mislabled.
