I send it&nbsp;CMD0 and CMD1 commands to reset and init it, the card answers proprely. But for example when I send it a CMD17 command in order to read a single block, first the answer is correct 0x00 and then the card send me the data. But the probleme is that the&nbsp;start block is 0xfc whereas it should be 0xfe and then there is the data from the card.
