//The FatFs module uses only device independent commands described below. Any device dependent function is not used.
//Command Description
//CTRL_SYNC Make sure that the disk drive has finished pending write process. When the disk I/O module has a write back cache, flush the dirty sector immediately. This command is not required in read-only configuration.
//GET_SECTOR_SIZE Returns sector size of the drive into the WORD variable pointed by Buffer. This command is not required in single sector size configuration, _MAX_SS is 512.
//GET_SECTOR_COUNT Returns total sectors on the drive into the DWORD variable pointed by Buffer. This command is used by only f_mkfs function to determine the volume size to be created.
//GET_BLOCK_SIZE Returns erase block size of the flash memory in unit of sector into the DWORD variable pointed by Buffer. This command is used by only f_mkfs function and it attempts to align data area to the erase block boundary. The allowable value is 1 to 32768 in power of 2. Return 1 if the erase block size is unknown or disk devices.
