[旧帖] [求助]《寒江独钓》上的磁盘还原程序ZwCreateFile返回0xC000003AL（STATUS_OBJECT_PATH_NOT_FOUND） 0.00雪花
2011-12-3 12:44
不说废话了，直接进入主题。
首先程序不是《寒江独钓》上原来的那个，是我在DegbgMan上的下的一个修改版。但核心部分没变。
问题是测试时在dfReinitializationRoutine中ZwCreateFile返回了0xC000003AL，即STATUS_OBJECT_PATH_NOT_FOUND，但按书上的说法，这里是不应该返回STATUS_OBJECT_PATH_NOT_FOUND，因为此时NTFS已经准备好了，一时没有头绪，不知根本问题出现在那里，请高手指教，下面是相关源码，对测试环境的简单介绍和一些崩溃信息。
测试环境：一共是两个盘，都已经是转换为NTFS系统，如下
下面是崩溃信息：
