4.5 Nikon D3100 Not compatable??? CLSXZ00 | 05/03/2012 | See all CLSXZ00's reviews (5) The card refused to work on my nikon D3100 and I was getting error messages stating card may be faulty ?? I formated the card and it still refused to be seen by my camera?? I tried the card in my Pc and its ok , I also tried it In my Sanyo Xacti video camera and it works fine?? Suggest you buy PNY versions as they work ok!!
