After nearly 5 years of trouble free use, my D5100 started refusing to detect my Sandisk 32Gb SD card.
I was luckily able to get my pictures off the disk, because my laptop would recognise it.
My local camera shop tried my disk in various of their own Nikon cameras, and tried various new and used disks in my camera all with no problems. The only thing that doesn't work is my disk in my camera.
They also reformatted the disk in one of their own cameras, and used a can of air to blow out the disk socket on the camera- still with no success.
In the end I bought a new disk, and the camera has worked OK since.
My question(s) are, does anyone know what went wrong, and is this sort of thing now going to happen more often?
Thanks
