I had several micro sd cards, which failed all the same type: They became locked read only. Two Samsung branded, so, I assume, it is not a problem of noname products, but something concerning wear levelling. Fortunately all data were present, as the sd card is completely unerasable. Unfortunately, the failure is not detected immediately, as data were chached before writing for some hours and finally are lost.
