使用S.M.A.R.T. Ioctl API获取IDE硬盘序列号
(http://www.tommstudio.com)
--------------------------------------------------------------------------------
通过它你可以获取型号名称, firmware revision，序列号以及其它有关IDE硬盘的信息.

许多FAQ中推荐使用GetVolumeInformation来获取硬盘序列号。但是那获取的是卷的序列号，而不是硬盘的序列号。卷 的序列号是在分区格式化时生成或修改。一些公司使用复制工具来为全部新计算机安装软件----通过将一个硬盘复制到 其它硬盘，当然，所有这些计算机上卷的信息（包括序列号）都是相同的。
我建议另外的一个方法：获取真正硬盘的序列号。
不幸的是，下列代码只能工作在IDE硬盘上。
