I was doing some test-flying today and my Pixhawk running Plane 3.3 stopped creating .bin files on the SD card. I removed the card to download the .bin file to my computer after the first flight, and after that it did not create another one for the subsequent three flights. I checked the LOG_BITMASK setting and it's set to default (on Mission Planner). The SD card is definitely seating and the pixhawk is reading it because I was able to delete all the previous .bin files on the SD card through mission planner. I had nine .bin files on the SD, the ninth being my first flight of the day, when it stopped recording.
Any ideas? It's particularly frustrating as I'm trying to work through an auto-takeoff issue and I can't figure out why the motor isn't powering up on launch; the log files would be tremendously helpful.

I was able to fix this by formatting the card in my computer.
