Take copies of the MBR and BPB then on the AVR card you can hard code the data of those two sectors into the AVR program and replace them if you But if you really want to maintain FAT then why not simply use FatFs from E L Chan? Compatibility GPT drives tend to include a "protective MBR." This type of MBR says that the GPT drive has a single partition that extends across the entire drive. news Shouldn't the card already come with a perfectly good FAT setup?
