5d iii not recording RAW

Issue #1960 invalid
Former user created an issue

Hi, I've recently downloaded ML, when I go to record video RAW it doesn't record. The red LED flashes and the green box in the top right on the screen flashes with the time as if it was recording however, when I return to playback what has supposedly recorded there is nothing there. Even when I connect it to my laptop there are no images. Yet when I got to format the flashcard data has been stored on there as if it has been recorded. Anyone any ideas why? Thanks.
