You can't mix it. Only one SD card slot.



Perhaps the

Mine only happens if SD slot is filled with SD card. I have not noticed this happening before I inserted the card.

I have fast Sandisk, Topram, Trenscend cards for CF. All of these create the same problem.

Take a look, more and more posters reporting the same problem.
One poster even said that there is nothing is SD slot and he still noticed the problem. I doubt very much that it has anything to do with the fake cards.

Don't need to. One poster here already reported what you suggested.

Hopefully Nikon will fix it in the next firmware update.
