用过超级兔子的都知道，有一个隐藏磁盘
的功能，选择隐藏的磁盘，确定后，
重新启动，看到磁盘隐藏了
主要是通过操作注册表来实现这个功能的
打开注册表
打开HKEY_CURRENT_USER\Software
\Microsoft\Windows\CurrentVersion
\Policies\Explorer分支
在这个分支下，NoDrives键值可以进行设置。
磁盘驱动器一一对应的键值如下：
A驱:0x00000001,B驱:0x00000002,
C驱:0x00000004,D驱:0x00000008,
E驱:0x00000010,F驱:0x00000020.
即按磁盘驱动器的英文字母顺序(A~Z)从十六进制的二倍数递增.将你要隐藏的磁盘驱动器所对应的键值按十六进制相加赋值给”NoDrivers”,如果要隐藏A,C,D,则将0x0000000D赋值给”NoDrives”
代码如下:WinXP+VB+SP6
winxp下注销重新登陆即可看到
添加list控件，command控件
