VC获得硬盘序列号

VC 之获取硬盘序列号
上一回，一帆风给大家讲了讲如何读取计算机的MAC地址，这次聊聊怎么获取硬盘序列号。

硬盘物理序列号是硬盘的出厂序列号，它是全球都是唯一的，不会随着系统的安装、硬盘的格式化等操作而改变，跟mac地址一样都具有唯一性。

1，第一步：创建设备对象，得到设备句柄，设备为硬盘。

{
CString sFilePath;
sFilePath.Format("\\\\.\\PHYSICALDRIVE%d", driver);
HANDLE hFile=::CreateFile(sFilePath,
GENERIC_READ | GENERIC_WRITE,
FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL, OPEN_EXISTING,
0, NULL);
DWORD dwBytesReturned;
GETVERSIONINPARAMS gvopVersionParams;
DeviceIoControl(hFile, //向设备对象发送SMART_GET_VERSION设备请求，获取硬盘属性
SMART_GET_VERSION,
NULL,
0,
&gvopVersionParams,
sizeof(gvopVersionParams),
&dwBytesReturned, NULL)；
if(gvopVersionParams.bIDEDeviceMap <= 0) return -2;
2。

第二步，发送SMART_RCV_DRIVE_DATA设备请求，获取硬盘详细信息。

// IDE or ATAPI IDENTIFY cmd
int btIDCmd = 0;
SENDCMDINPARAMS InParams;
int nDrive =0;
btIDCmd = (gvopVersionParams.bIDEDeviceMap >> nDrive & 0x10) ?
IDE_ATAPI_IDENTIFY : IDE_ATA_IDENTIFY;
// 输出参数
BYTE btIDOutCmd[sizeof(SENDCMDOUTPARAMS) + IDENTIFY_BUFFER_SIZE - 1];
if(DoIdentify(hFile,
&InParams,
(PSENDCMDOUTPARAMS)btIDOutCmd,
(BYTE)btIDCmd,
(BYTE)nDrive, &dwBytesReturned) == FALSE) return -3;
::CloseHandle(hFile);
DWORD dwDiskData[256];
USHORT *pIDSector; // 对应结构IDSECTOR，见头文件
pIDSector = (USHORT*)((SENDCMDOUTPARAMS*)btIDOutCmd)->bBuffer;
for(int i=0; i < 256; i++) dwDiskData[i] = pIDSector[i];
// 取系列号
ZeroMemory(szSerialNumber, sizeof(szSerialNumber));
strcpy(szSerialNumber, ConvertToString(dwDiskData, 10, 19));
// 取模型号
ZeroMemory(szModelNumber, sizeof(szModelNumber));
strcpy(szModelNumber, ConvertToString(dwDiskData, 27, 46));
return 0;
}
BOOL __fastcall DoIdentify( HANDLE hPhysicalDriveIOCTL, PSENDCMDINPARAMS pSCIP,
PSENDCMDOUTPARAMS pSCOP,
BYTE btIDCmd,
BYTE btDriveNum,
PDWORD pdwBytesReturned)
{
pSCIP->cBufferSize = IDENTIFY_BUFFER_SIZE;
pSCIP->irDriveRegs.bFeaturesReg = 0;
pSCIP->irDriveRegs.bSectorCountReg = 1;
pSCIP->irDriveRegs.bSectorNumberReg = 1;
pSCIP->irDriveRegs.bCylLowReg = 0;
pSCIP->irDriveRegs.bCylHighReg = 0;
pSCIP->irDriveRegs.bDriveHeadReg = (btDriveNum & 1) ? 0xB0 : 0xA0;
pSCIP->irDriveRegs.bCommandReg = btIDCmd;
pSCIP->bDriveNumber = btDriveNum;
pSCIP->cBufferSize = IDENTIFY_BUFFER_SIZE;
return DeviceIoControl( hPhysicalDriveIOCTL,
SMART_RCV_DRIVE_DATA,
(LPVOID)pSCIP,
sizeof(SENDCMDINPARAMS) - 1,
(LPVOID)pSCOP,
sizeof(SENDCMDOUTPARAMS) + IDENTIFY_BUFFER_SIZE - 1, pdwBytesReturned, NULL);
}
char *__fastcall ConvertToString(DWORD dwDiskData[256], int nFirstIndex, int nLastIndex)
{
static char szResBuf[1024];
char ss[256];
int nIndex = 0;
int nPosition = 0;
for(nIndex = nFirstIndex; nIndex <= nLastIndex; nIndex++)
{
ss[nPosition] = (char)(dwDiskData[nIndex] / 256);
nPosition++;
// Get low BYTE for 2nd character
ss[nPosition] = (char)(dwDiskData[nIndex] % 256);
nPosition++;
}
// End the string
ss[nPosition] = '\0';
int i, index=0;
for(i=0; i<nPosition; i++)
{
if(ss[i]==0 || ss[i]==32) continue; szResBuf[index]=ss[i];
index++;
}
szResBuf[index]=0;
return szResBuf;
}。
