a. 这里没有考虑SCSI硬盘
b. 要使用的几个相关头文件和库文件在附件中
c. 调用事例：
char szHardDiskID[100] ={0}; //一般来说，硬盘的物理序列号长14字节
GetDiskPhysicalSN(szHardDiskID);
d. 下面是计算的全部代码：
//需要自定义的常量和结构为：
// IOCTL 指令常数
#define DFP_GET_VERSION 0x00074080

// 用于 IDEREGS 结构 bCommandReg 项的有效值
#define IDE_ATAPI_IDENTIFY 0xA1
#define IDE_ATA_IDENTIFY 0xEC
#define IDENTIFY_BUFFER_SIZE 512
// 结构体定义
// 保存磁盘驱动器的信息
