Hi,
My two-week old Nikon D3400 has two issues I need your help with.
First, it reads and formats all SDHC cards, including SanDisks, EXCEPT for my 64GB SanDisk Extreme Pro U3, C10 card. I bought this card specifically for the camera, based upon on-line reviews that not only said it worked, but was very fast.
My computer reads, formats, and benchmarks this 64GB card without problem or bad sectors.
Second, after turning on the camera, it defaults to single picture mode. I change that setting to burst, but the camera will NOT save burst mode the next time I turn on the camera. Please advise.
thanks!
