的CreateFile：直接写操作原始磁盘和QUOT;访问被拒绝＆QUOT; - Vista中，Win7的 [英] CreateFile: direct write operation to raw disk "Access is denied" - Vista, Win7
问题描述
有关微软文档是：
阻止直接写操作卷和磁盘
<一href="http://msdn.microsoft.com/en-us/library/windows/desktop/aa363858%28v=vs.85%29.aspx#physical_disks_and_volumes">CreateFile,言论对物理磁盘和卷
The relevant Microsoft doc is:
Blocking Direct Write Operations to Volumes and Disks
CreateFile, remarks on Physical Disks and Volumes
该可执行文件是用C ++编写，并调用的CreateFile（）打开SD卡，有无文件系统。该的CreateFile（）和连续的ReadFile（）呼叫成功为 GENERIC_READ 无需管理员权限。
The executable is written in C++ and it calls CreateFile() to open an SD card that has no filesystem. The CreateFile() and consecutive ReadFile() calls are successful for GENERIC_READ without Administrator privileges.
的CreateFile 失败 GENERIC_WRITE 甚至具有管理员权限。在资源管理器，我设置运行方式下的属性>兼容性>特权级别管理员。我也试着运行管理员CMD的可执行文件（开始按Ctrl + Shift + Enter键，管理员：是在窗口标题，适当提高）。不过，我得到 ERROR_ACCESS_DENIED （0x5的）。
CreateFile fails for GENERIC_WRITE even with Administrator privileges. In the explorer, I set Run as Administrator under Properties > Compatibility > Privilege Level. I also tried to run the executable from an Administrator cmd (started with Ctrl+Shift+Enter, "Administrator:" is in the window title, properly elevated). Still, I get ERROR_ACCESS_DENIED (0x5).
我一定要通过别的事情的CreateFile ？我不知道什么样的安全属性，我只是传递NULL，<一个href="http://szte-wsn.svn.sourceforge.net/viewvc/szte-wsn/private/ali/RawToCType/Win32DeviceHelper.cpp?revision=2949&view=markup">relevant code是这里在线路92和<一href="http://szte-wsn.svn.sourceforge.net/viewvc/szte-wsn/private/ali/RawToCType/Win32DriveFormatter.cpp?revision=2940&view=markup">here在48行。
Do I have to pass something else to CreateFile? I have no idea what security attributes are, I just pass NULL, relevant code is here at line 92, and here at line 48.
或者是还有其他应设置为运行具有管理员权限的进程？
一个相关的问题：
Or is there anything else that should be set to run the process with Administrator privileges?

推荐答案
这是相当罕见的只想要 GENERIC_WRITE 。您很可能希望 GENERIC_READ | GENERIC_WRITE 。
It's quite rare to want only GENERIC_WRITE. You most likely want GENERIC_READ|GENERIC_WRITE.
