3 years ago I bought a Radio Shack Camera Shield 2760248 and an SD Shield. Little did I know that this old SD shield would only work with old SD cards (no SDHC and FAT32 cards) no larger than 4GB. Where can you find SD cards that are 4GB or less? I had a lot of SD and micro SD cards. This new SD Shield 3.0 now supports all my SD cards. There is a new Arduino library. Instead of "sdFat.h" I add "SD.h" and it just works. Works perfectly.
