Epson P-2000 and SDHC card ?
I just tried using Lexar Professional 8GB SDHC 133x speed card and it does not work, I then used Lexar Professional 8GB CompactFlash UDMA card and it worked. Both using Nikon NEF files from D300s. The SDHC card does not work with JPG either and the CompactFlash UDMA card does. It is the card I guess, plus the P-2000 is old.
