Well, Im an idiot who got the 4 gig card for the D50, later realizing that it only supports 2 gig. So now I have this card. It has not been formatted, due to no way of doing it. Please note that this card is SDHC format, so older card readers I believe will not read this. Could be a good pick up for someone with a D40 though. Only asking $35 + shipping, which will be low for such a small item.
