This is the second time this has happened to me and I am in a panic! I am not sure if the culprit is my new Sony A6000 or a bad SD Card. I had mini sessions this morning and after my second family I saw that I could not playback the most recent images in camera. Since this happened once before I switched out my SD card for a new one before my next family arrived. When I got home I crossed my fingers and prayed but just as the last time the begining images were fine but ALL the images after a certain point cannot be previewed or opened in photoshop. (Note they are all Sony .arw files. Not sure if this matters) I can see that they exist but the thumbnail does not populate and when I try to open in CS6 it says "Could not complete your request because Photoshop does not recognize this type of file." Please tell me there is hope! Thank you SO much in advance for any guidance.
