[请教高手]加载驱动失败?

        再一次遇到问题,希望高手可以解答,先谢谢了!
        在DriverEntry()中动态枚举文件系统后绑定驱动器时,状态是成功的,可是当DriverEntry()加载结束后,驱动收到几个不明的SfPassThrough消息后就蓝屏了,蓝屏后截图如附件第一张图所示:
        同时如果选择系统启动时静态加载时,到硬盘时也是遇到如图的问题.
        但是如果去掉XP下的动态枚举那部分代码,动态加载U盘时却是成功的,后面的过滤工作也可以正常进行.
        下面是加载U盘后的一些调试信息:

     请问高手加载U盘(FAT)和硬盘(NTFS)有什么不同,为什么加载NTFS后收到几个SfPassThrough消息就蓝屏了,是加载硬盘时需要一些特殊的操作吗?.为这个问题已经苦恼多时了,望高手解答?
