I just took a bunch of photos at a swim meet for some of the parents, and when I loaded the card into the card reader, the photos could not be imported because the files were unrecognizable in Lightroom 5. Lightroom tells me that "it cannot read the preview / preview unavailable for this file." I was able to load two photos, but they were damaged. I then put the card back into the camera to see if the camera could read the card, and the display said that "it is unable to display" the photos.
I shoot with a Sony a900. I used the 70-200/2.8G. The only thing I did differently today was turn off the D Range Optimizer. All other settings remained the same.
There was a very light sprinkling of rain at the pool, but the camera did not get wet as far as I can tell. I am very careful about that.
Before I left the meet, and well after the light rain, I checked the photos in camera and they were still on the card. After the meet, I put the camera on the floor of the car while I ate lunch. Then when I arrived home I popped the card into the reader, and this nonsense happened.:
Can anyone tell me what happened and how I can recover the photos? In the meantime I will load another card into the camera to see if it works. If so, the card went bad at the wrong time.
