我尝试使用下面的代码来获取MBR来自PhysicalDrive0:

private static byte[] ReadMbr(string lpFileName)
{
   byte[] mbr = new byte[512];

   using (SafeFileHandle drive = CreateFile(
         lpFileName: lpFileName,
         dwDesiredAccess: (uint) EFileAccess.GenericRead, //DO NOT MODIFY THE MBR!!!
         dwShareMode: (uint)EFileShare.Write | (uint)EFileShare.Read | (uint)EFileShare.Delete,
         SecurityAttributes: IntPtr.Zero,
         dwCreationDisposition: (uint) ECreationDisposition.OpenAlways,
         dwFlagsAndAttributes: (uint)EFileAttributes.System,
         hTemplateFile: IntPtr.Zero))
   {
      if (drive.IsInvalid)
         throw new IOException("Unable to access drive. Win32 Error Code " + Marshal.GetLastWin32Error());

      //Get the 1st 512 bytes of the volume (MBR)
      using (FileStream stream = new FileStream(drive, FileAccess.Read))
      {
         stream.Read(mbr, 0, …
