<p>Just got the D810 home.<br> Inserted one of the memory cards I was using in my D4, a Delkin Devices 32G (UDMA 6).<br> The D810 gives a message saying it cannot format the card, that it might be defective.</p> <p>I popped it into the D4. No problem formating or using this card.<br> Back to the D810. It still will not format (or read) the card. <br> Bizar.<br> My other CF card, a SanDisk extreme 32G (UDMA) works in both cameras, no problem.<br> I find it strange that the D4 has no issue with either card but the D810 does.</p> <p> </p>
