I've just had a strange problem occur on a SD card used in my 5D3 and I'd be interested if anyone else has seen this
The 5D3 is set up to store Raw on the CF card and JPEG on the SD card. To transfer the JPEG files to the backup drive I always put the card into a PC or laptop and do the copying from there. Tonight it was a WIN10 laptop
I was doing this backup of the JPEGs this evening, all were copied and a large number deleted (not all as it's a 32GB card and has more than enough space). As far as I know it completed normally and I put the card back into the camera. However this time the drive light on the camera was red for a long time and when it finished it reported that there were no images to display when you tried to look at them. Put the card back into the laptop and all files were shown and could be opened normally.
Put the card back into the camera and took a pic, worked normally and showed the pic but it was the only pic that could be displayed! As all the files on the card had been backed up anyway I reformatted it, the menu announced that the card was half full so it knew there was data on it although it said there were no images to display.
Anyway the cards now reformatted and I am going to get a another one just in case. The card seemed to be working ok in the laptop and it was working ok in the camera as that had no problem in accessing it and reformatting it; all I can imagine is that putting the card into the laptop did something to the JPEG file to render it unreadable by the camera.
If anyone else has had this issue or can shed any light I'd be interested to hear.
