I think I experienced this problem myself the first time I recorded anything with my EX1R. I did some test recording and the clips were all listed properly in the viewfinder in media mode. The next day I wanted to look again at one clip in particular and all the clips were missing, although the camera reported that the same amount of space on the card was still used up. The clips were not important but what was important (obviously) was that the clips were missing. I didn’t pursue the issue and it’s never happened since.
The other day I was in record mode and the camera had just finished switching slots. In the dark I mistakenly pushed the wrong eject button and the card being recorded to popped out. That’s a first for me. Oops. I put the card back in and the EX1R immediately asked to restore the card, which I did. There was no issue and all the clips remained fine. All of the above experiences were with SxS Pro 32Gbyte memory cards.
Anyway………
I’m wondering if the above experience rings a bell with Kimberly. If the SxS card with the missing media is still reporting that there is space used up then your clips are still there but it’s more of a directory issue on the card. Try mounting the card on your computer desktop and using something like DiskWarrior to scan for a directory and possibly re-build/restore it.
