vc控制台程序如何获取整个硬盘的扇区数？

taoym101 2010-6-10 20:23 楼主

就是在win32 console程序下，通过什么方式可以获取硬盘的总扇区数？
api函数? 转为16位模式调int 13?

另外就是对硬盘的直接读写除了createfile（），还有其他什么方式吗？

zwfgdlc的代码我看过，不个那样获取的CHS值都是对的，但算出来的总扇区数（三数相乘）却不正确，用diskgen查了哈，算出来的扇区始终比 dgen显示的总扇区小一些。
我在想可以用什么函数直接获取总扇区数。eg : IOCTL_DISK_GET_DRIVE_GEOMETR_EX这个值，不个正遇到编译错误，正在修改………………
