大师，我移植了FATFS到flash，发现格式化未成功（未移植文件系统时多扇区（n*512B）读写没问题，已经测试过），如何配置格式化函数呀：

#define _MAX_SS 512 /* 512, 1024, 2048 or 4096 */
/* Maximum sector size to be handled.
/ Always set 512 for memory card and hard disk but a larger value may be
/ required for floppy disk (512/1024) and optical disk (512/2048).
/ When _MAX_SS is larger than 512, GET_SECTOR_SIZE command must be implememted
/ to the disk_ioctl function. */

/*-----------------------------------------------------------------------*/
/* Miscellaneous Functions */

DRESULT disk_ioctl(
BYTE drv, /* Physical drive nmuber (0..) */
BYTE ctrl, /* Control code */
void *buff /* Buffer to send/receive control data */

//DWORD result;
