NIKON D90 “CHA” ERROR

This error is quite common with Nikon DSLR cameras and shows up quite often with D90 users, myself included. Usually removing and reinstalling the SDHC memory card will clear it up. Additionally if possible format the memory card.

I get this error with my two Sandisk and my Eye-Fi Pro X2 SDHC memory cards.

This is a Nikon issue. Don’t blame the memory card vendors.
