Hello, After reviewing the manual, and two books I have on Nikon 7000, I cannot find how to switch back to using only card slot 1 (with card slot 2 as overflow). I can't even format card in slot 1 because I'm apparently stuck on card slot 2 when I changed once. When I try, it says this option is "not available with current settings".
So, folks, how do I go back to simply using card slot 1 so I can format my full card?
I know, this should be simple, but after an hour, I must be missing something.
