这个应用程序演示了如何直接地访问物理驱动-读取/编写扇区/簇，可和MBR, FAT,根目录等一块运行。包括了一个函数，能用来搜索坏了的簇，例如磁盘检查工具。它的局限性是它只能和FAT驱动一块运行（FAT12, FAT16,和FAT32），且不支持大的驱动器。-the application demonstrated how direct access to physical drive-reading / preparation Sector / cluster, and the MBR, FAT, such as a root directory operations. Includes a function can be used to search out of the cluster, such as disk diagnostic tools. Its limitations is that it can only run a FAT drive (FAT12, FAT16 and FAT32), which did not support the drive.
