Non-HC (high capacity) memory cards are very hard to find these days. My Nikon D50 DLSR cannot read SDHC cards and requires normal SD cards. The upper size limit for normal SD cards seems to be 2 GB. My camera reads and describes these cards perfectly. If you have an older device that can't use the SDHC format, they might work for you. they definitely work for me. I stock up when I can't get them anymore (I have a feeling this will happen sooner rather than later).
