The lower 2048 bytes of the 4k card (sectors 0 – 31) are organised in the same way as the 1k
card. However the upper 2048 bytes are organised as eight large sectors of 16 blocks each
(sectors 32 – 39). Taking into account the Serial Number/Manufacturers Block and the Sector
Trailer Blocks then there are 3440 bytes of free memory for user storage.
