硬盘序列号在 Windows XP、Vista 和 7 中每 2 个字节翻转一次，但在 Windows 8 中没有 [英] HDD serial number flipped every 2 bytes in Windows XP, Vista and 7 but not in Windows 8

问题描述

我需要获得硬盘序列号才能将其用作许可软件的密钥.我在这个 url 中使用了 diskid32 代码:http://www.winsim.com/diskid32/diskid32.html它使用 DeviceIoControl Win32 API 和 IOCTL_STORAGE_QUERY_PROPERTY 的 IO 控制代码.

I need to get HDD serial number to use it as a key for licensing a software. I used diskid32 code in this url: http://www.winsim.com/diskid32/diskid32.html It used the DeviceIoControl Win32 API with the IO control code of IOCTL_STORAGE_QUERY_PROPERTY.

它奏效了.然而，当我仔细检查打印在硬盘本身上的实际序列号时，我发现该数字的每 2 个字节都被翻转了.

It worked. However, when I double check with the actual serial number printed on the HDD itself, I found that every 2 bytes of the number was flipped.

一个简单的解决方案可能是简单地翻转字节.它适用于 Windows XP、Vista 和 7，但在 Windows 8 中不需要翻转！

A simple solution could be to simply flip the bytes back. It worked in Windows XP, Vista and 7 but in windows 8 not need to be flipped!

我想知道在 Windows XP、Vista 和 7 中字节翻转的确切原因，而在 Windows 8 中为什么不翻转.下一个 Windows 怎么样?

I wish to know the exact reason why the bytes were flipped in Windows XP, Vista and 7, and why not flipped in Windows 8. What about next Windows?

部分代码略有改动:

  int drive = 0;
  HANDLE hPhysicalDriveIOCTL = 0;
  char driveName [256];
  sprintf (driveName, "\\\\.\\PhysicalDrive%d", drive);
  //  Windows NT, Windows 2000, Windows XP - admin rights not required
  hPhysicalDriveIOCTL = CreateFile (driveName, 0,
                           FILE_SHARE_READ | FILE_SHARE_WRITE, NULL,
                           OPEN_EXISTING, 0, NULL);
  if (hPhysicalDriveIOCTL != INVALID_HANDLE_VALUE)
  {
     _STORAGE_PROPERTY_QUERY query;
     DWORD cbBytesReturned = 0;
     char buffer [10000];

     memset ((void *) & query, 0, sizeof (query));
     query.PropertyId = StorageDeviceProperty;
     query.QueryType = PropertyStandardQuery;

     memset (buffer, 0, sizeof (buffer));

     if ( DeviceIoControl (hPhysicalDriveIOCTL, IOCTL_STORAGE_QUERY_PROPERTY,
               & query,
               sizeof (query),
               & buffer,
               sizeof (buffer),
               & cbBytesReturned, NULL) )
     {
         _STORAGE_DEVICE_DESCRIPTOR * descrip = (_STORAGE_DEVICE_DESCRIPTOR *) & buffer;
         char serialNumber [1000];
         char modelNumber [1000];
         char vendorId [1000];
         char productRevision [1000];

         flipAndCodeBytes (buffer,
                           descrip -> SerialNumberOffset,
                           1, serialNumber );

        ...
     }

推荐答案

只需在 windows 8 或更高版本时使用 flibAndCodeBytes 函数的翻转"标志关闭翻转.

Just turn off the flip using the "flip" flag of the flibAndCodeBytes function when windows 8 or greater.

bool shoulFlipBytes = true;
if(IsWin8OrLater()) shouldFlipBytes = false;

flipAndCodeBytes(buffer,
                 descrip->SerialNumberOffset,
                 shouldFlipBytes,
                 serialNumber);

您可以使用它来检查 Windows 版本:

You can use this to check for windows version:

#include <windows.h>

bool IsWin8OrLater() {
    DWORD version = GetVersion();
    DWORD major = (DWORD) (LOBYTE(LOWORD(version)));
    DWORD minor = (DWORD) (HIBYTE(LOWORD(version)));

    return (major > 6) || ((major == 6) && (minor >= 2));
}
