Comment(by wad):

 Looking at the state diagram in figure 4-13 of the SD spec, the card is
 still waiting for the end of the last read/write transaction to complete.

 We should try to figure out why this is the case.

 Correct error recovery in this case is to issue a CMD12 (STOP), which
 should return the device to the transfer state, in which the
 SET_BLOCK_COUNT command can be issued.
