Extreme Pro 128GB SDXC V30 UHS-I Card

My brand new 128GB Extreme Pro SDXC V30 I UHS-I does not work on my two cameras Nikon D800 and Brand new D500.

I could not either format the card on both cameras.

Just had the same results on my D800 & D810 with the same 128GB card as well.
Shipping mine back but would be good to know why.

Same issue with same card on D800 & D810. 
Shipping mine back to BH.

  • Remove battery, Memory card, and lens for about 30 seconds
  • Reinsert just the lens and the battery, power the camera on ensure you are using an approved card
  • The camera settings can be restored to default values by holding the “Menu” and “i” buttons down together for more than two seconds
    (these buttons are marked by a green dot). The information display turns off briefly while settings are reset.
  • Hit the menu button and select custom setting menu
  • Select “F” for controls and then “F4” labels " Slot empty release lock"
  • Highlight “Enable release”
  • Test camera with no card/ then reinsert the card and try again

I am sure that these intructions will perfectly resolve your issue. For more help and support you can use Nikon D800 Manual
