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?

Assuming the camera was set forOverflowI have no explanation other than a camera body issue that could be either firmware or hardware.As it's free, easy, and quick, I suggest doing atwo button reset, verifying the setting ofOverflow, and retesting. I've found this cures a fair number of poltergeist-in-the-cpu sort of errors.If that doesn't get it a trip to the shop may be indicated.
