now it is my turn. I have sony combined xqd and sd reader, which does not function with my xqd cards today.I have tried xqd from both D500 and D850 with same negative result but I can. see the images in the cameras. I have tried 2 cards in the reader with 3 computers. I have copied the images from the xqd to the sd in the D500 and then used the same reader to transfer to computer. is it possible that the xqd connection to the computer is damaged but the SD connection is ok?
