查找Windows设备

我使用下面的办法查找C:盘对应的设备

InitializeObjectAttributes(&objectAttributes, pDiskName, OBJ_CASE_INSENSITIVE | OBJ_KERNEL_HANDLE, NULL, NULL );
  
  status = ZwCreateFile(&ntFileHandle,
                        GENERIC_WRITE,//SYNCHRONIZE|FILE_ANY_ACCESS,
                        &objectAttributes,
                        &ioStatus,
                        NULL,
                        0,
                        FILE_SHARE_READ|FILE_SHARE_WRITE,
                        FILE_OPEN,
                        FILE_SYNCHRONOUS_IO_NONALERT|FILE_DIRECTORY_FILE,
                        NULL,
                        0);
  if (!NT_SUCCESS(status))
  {
     KdPrint( ("shar: Failed to open %ws. Error Code: 0x%xL\n", pDiskName, status) );
     DbgPrint(("shar: Could not open drive\n"));
     return FALSE;
  }
  else
  {
     DbgPrint(("shar: Open Device is OK\n"));
  }

可是老是打开不成功，不知道哪位兄弟知道为什么

What is the disk name you are using? What error code you got?

他们都成功  但是使用这个DiskDeviceObject = IoGetRelatedDeviceObject(fileObject); 找到设备对象 并将我新创建的设备绑定到其上时 出现了*** Fatal System Error: 0x0000006b
                       (0xC0000010,0x00000002,0x00000000,0x00000000)

Break instruction exception - code 80000003 (first chance)

A fatal system error has occurred.
Debugger entered on first try; Bugcheck callbacks have not been invoked.

A fatal system error has occurred.

绑定是用这个绑定的 IoAttachDeviceToDeviceStack(MyDevice,DiskDeviceObject);
