果电脑主人上次用正确密码进入了电脑,而电脑非法使用者一次都不试密码，就直接用软盘或光盘或
USB盘引导，那么就可以非法访问硬盘了，说实话，这个问题困扰了我许久，一直不得其解，不这样做，
就得在输入正确密码后就将正确的分区表读入0柱0道1扇，然后在操作系统启动后再做手脚把0柱0道1扇的
分区表加密，这样做有两个问题，(1)操作系统启动做的手脚一定是放在操作系统的自启动中(如DOS的
AUTOEXEC.BAT、WIN98的"启动"等)，这样做显然不安全，(2)同时这样做显然不能做到"跨平台",所以我只
能在程序说明中告诉使用者,如果离开电脑,就故意输入一错误密码,那么江明锁就将硬盘锁死了,这样电脑
非法使用者用软盘或光盘或USB盘都不能引导了,(大家知道所谓江明锁,就是让扩展分区指向自己,从而使
启动程序陷入死循环,这个该死的东西也不知害死了多少硬盘,也该让他做做好事了),要是谁有更好的方法
解决这一问题,一定要告诉我.
再来介绍一下HDLCOK.EXE文件，以下是完整的程序源代码： ;硬盘锁安装程序
