Good stuff! Does this mean that if the csd.c_size read from the card should be doubled on 2GB cards? Then the 2GB card can be treated by the software exactly as if it were a 1GB card, but, with twice as many blocks? While on the subject, would you know how 4GB cards can be accessed? The little information that I have found indicates that the SDHC (High Capacity) has not yet caught on and that large SD cards do not follow a clear standard.
