D750 slot 2 issue
Hi there. I use a large card in slot 1 so rarely go over into slot 2 as the overflow. Today I was at an all day event so did go over. All pictures I took previewed for a second in the usual manner, but it seems none of them were actually saved to the card. When you press the play button it says 'Cannot display this file.' As I was seeing previews I didn't press the play button until the end of the day, only to find out there was nothing on card 2.
The card on its own works fine. Tried a different card in slot 2 with the full card in slot 1, same thing happened. Have lost an entire afternoon that I'll never see again.
Anyone else came across this problem?
