Problems with new memory cards

[NateNLogansDad]

The camera: Nikon D5100

The cards: both are Sandisk 16GB Extreme 30 MB/s

The problem I'm having is that when I'm shooting, every once in a while the camera tells me that there is either an error or "No SD Card Inserted." If I pop the card out and put it right back in, it works fine again.

I took the first card back the day after I bought it but now the second card is doing the same thing and it's driving me nuts. Is it possible that Best Buy just had a bad batch or is there some sort of chemical film that needs to be wiped away?

It's driving me nuts so if anybody has any ideas I would really appreciate it!

It sounds like a bad batch to me.

Have you formatted each card before using it? If not, try that to see if that clears up your problem.
