如何得到唯一的硬盘序号

不正确的序列号

利用GetVolumelnformation获取的计算机硬盘卷序列号，不是正确的唯一序列号：

01.voidCWJGISApp::Register()

02.{

03.    DWORDVolumeSerialNumber;

04.    GetVolumeInformation("c:\\",NULL,NULL,&VolumeSeriaINumber,NULL,NULL,NULL,NULL);

05.    charcharVolumeSerialNumber[l0];

06.    itoa(VolumeSerlalNumber,charVoIumeSerialNumber,10);

07.    CString strTemp;

08.    strTemp.Format("%s",charVolumeSerialNumber);

09.}

该函数获取的序列号在硬盘格式化后会发生变化。

正确获取硬盘的序列号

正确获取硬盘序列号代码如下：

//读般硬盘序列号函数char* CGetHDSerial::GetHDSerial(){m_buffer[0]='\n';//得到当前操作系统版本OSVERSIONINFO OSVersionInfo;OSVersionInfo.dwOSVersionInfoSize = sizeof(OSVERSIONINFO); GetVersionEx(&OSVersionInfo);if(OSVersionInfo.dwPlatformld != VER_PLATFORM_WIN32_NT){//Windows 9x/ME下读取硬盘序列号WORD m_wWin9xl'HDSerial[256];Win9xReadHDSerial(m_wWin9xHDSerial);strcpy (m_buffer, WORDToChar(m _wWin9xHDSerial, 10, 19));}else{//Windows NT/2000/XP下读取硬盘序列弓DWORD m_wWinNTHDSerial[256];//判断是否有SCSI硬盘if (!WinNTReadIDEHDSerial(m_wWinNTHDSerial))WinNTReadSCSIHDSerial(m_wWinNTHDSerial);strcpy (m_buffer,DWORDToChar(m_wWinNTHDSerial,10, 19));}return m_buffer;}//Windows NT/2000/XP下读取IDE硬盘序列号BOOL CGetHDScriaI::WinNTReadIDEHDSerial(DWORD* buffer){ BYTE JdOutCmd [sizeof(SENDCMDOUTPARAMS)+IDFNTIFY_BUFFER_SIZE - 1];BOOL bFlag = FALSE;int drive = 0;Char driveName[256];HANDLE hPhysicalDrivelOCTL=0;Sprintf(driveName,"\\\.\\PhysicalDrive%d",drive);//Windows NT/2000/XP 下创建文件需要管理员权限hPhysicalDriveIOCTL=CreateFile(driveName,GENERIC_READ|GENERIC_WRITE,FILE_SHARE_READ|FILE_SHARE_WRITE,NULL,OPEN_EXISTING,0,NULL);if(hPhysicalDriveIOCTL!=INVALID_HANDLE_VALUE){GETVERSIONOUTPARAMS VersionParams;DWORD cbBytesReturned=0;//得到驱动器的I/O控制器版本memser((void*)&VersionParams,0,sizeof(VersionParams));if(DeviceIoControl(hPhysicalDriveIOCTL,IOCTL_GET_VERSION,NULL,0,&VersionPaiams,sizeof(VersionParams),sizeof(VersionParams),&cbBytesReturned,NULL)){if(VersionParams.bIDEDeviceMap>0){BYTE bIDCmd=0;//IDE或者ATAPI识别命令 SENDCMDINPARAMS  scip;//如果驱动器是光驱，采用命令IDE_ATAPI_IDENTIFY，command，否则采用命令IDE_ATA_IDENTIFY读取驱动器信息bIDCmd=(VersionParams.bIDEDeviceMap>>drive&0x10)?
