rick65000,

You need to take your sdhc cards and format them on a digital camera that takes sdhc cards. Mac, PC's and Nokia have not seen fit to recognize the need to install drives for sdhc card formatting. Camera makers have. I had same problem and I followed a friends advise and took them to BestBuy and within 30 seconds the camera reformatted them properly. It didn't cost me a penny. Hope this helps and pass on the info to others. lol, Dan
