The cars seemed great, but occasionally the card is suddenly &#34;not formatted&#34;, even without writing new data to it. Has happened in multiple devices.I lost some video I can't rerecord on it, and am fairly upset.Some forums say that the early runs of these cards did that occasionally and that it has been fixed on new runs, but I find it difficult to trust them now. I have never had this problem with any SanDisk product before, including the 5 of these cards I have in 32GB.Very disappointed.
