Recently when shooting with 6D, I noticed that occasoinally images did not pop up on LCD. Since I rarely chimp., I thought that images had merely closed down before I had checked. When I previewed images on ProSelect, all were there. However, when checking in Lightroom, thumbnails were replaced with the 'Preview Unavailable' message above. No luck opening with CS5 or Digital Photo Pro either.
I switched card, and shot about 50 more images (so far) with no problem. What's worse is that client chose images which showed in ProSelect, but aren't opening anywhere else.
So far, it seems like this might be an individual card problem (Sandisk Extreme 32g 45 MB/S), since problem has not reappeared on a similar card. I'm just wondering if this has happened to anyone else and/or if anyone thinks this may be a camera problem. Problem did not occur (on same card) on multiple shoots - just started.
Thanks for your knowledge and advice.
