One of the "somethings" about cheap cards is that some of them are smaller cards programmed to claim to be larger. (There's a whole little programmable computer in that little card, it's not just a memory chip.) If you fill the card, then write something to it, and the memory chip is smaller than the card claims to be, the memory chip gets wiped.
So you pay $5 for a 32GB Class 10 card, and what you're getting is a 2GB card, reprogrammed and with new printing on it. Put 2GB on it and you're fine. Save a 1KB text file and the card gets wiped. If you run
SD Insight on a card like that, you may find that it was "manufactured" before microSD cards were invented (like 1970 or something).
