用”SMARTVSD.VXD“技术获得硬盘出厂序列号可靠吗？(10分)

用”SMARTVSD.VXD“技术获得硬盘出厂序列号可靠吗？
请发表见解
1、98，2000，XP下通用吗？
2、受其他限制吗？

vxd技术在win2000及以上已经不再使用了。
搜一下论坛，有很多源代码。
我试过别人的代码，基本上不同系统不同实现方法。
应该没什么限制，我试了大概10台机子左右。

既然"vxd技术在win2000及以上已经不再使用了。"，那么
可以说使用该技术获得硬盘出厂序列号“在win2000及以上”将
得不到技术支持，进一步说明这种方法不可靠或不推荐的，
那么有什么方法解决这个问题？

接受答案了.

你可以到这个网站看看:http://www.tommstudio.com, 搜索一下序列号.
下面贴出我下的一个例子,该例子在win9x/2k/xp下测试过,都能取出硬盘
序列号,不过9x下要拷贝一下文件,里面有叙述.
