I ran into a problem with the Nikon D5100 when inserting a new unformatted SanDisk Ultra SDHC 16GB memory card. The camera was not able to format the card and claimed that no memory card was inserted. Fortunately, another camera was able to recognize and format the card. After inserting the card back to D5100 the card was recognized by the camera, and allows formatting the card.
Have you solved this problem ? update a and b firmware to the 1.01 everything works after that.

"Modifications enabled with firmware A:1.01 / B:1.01
An error where the card may not have been recognized when some memory cards were used has been addressed.
When Selective color from the retouch menu is performed on a picture taken with the image quality set to NEF (RAW)+JPEG and an image size of M or S, the edges of the image may not have changed color. This issue has been resolved.
When Metering was set to Matrix metering, the exposure mode set to M (Manual), and the HDR exposure differential set to Auto, the exposure differential was fixed at a value equivalent to 2 EV. This has been changed to enable automatic adjustment of exposure differential so that it is appropriate for the scene"
