硬盘的ATA Command操作

[ljl2034]

下面是下SMART Command的code，哪位大神可以帮帮我呢？

 ATA_PASS_THROUGH_EX stCIP={0};
    ATA_PASS_THROUGH_EX stCOP={0};
    BOOL bRet=FALSE;
    DWORD dwRet=0;

    stCIP.AtaFlags = ATA_FLAGS_DATA_IN;
    stCIP.DataTransferLength = READ_ATTRIBUTE_BUFFER_SIZE;
    stCIP.CurrentTaskFile[0] = 0xd0;//Features
    stCIP.CurrentTaskFile[1] = 1;//Sector count
    stCIP.CurrentTaskFile[2] = 0;//Sector number
    stCIP.CurrentTaskFile[3] = SMART_CYL_LOW;//Cylinder low
    stCIP.CurrentTaskFile[4] = SMART_CYL_HI;//Cylinder high
    stCIP.CurrentTaskFile[5] = 0xE0;//Device/head
    stCIP.CurrentTaskFile[6] = 0xB0;//Command

    bRet=DeviceIoControl(hDevice,IOCTL_ATA_PASS_THROUGH,
                         &stCIP,sizeof(ATA_PASS_THROUGH_DIRECT)+READ_ATTRIBUTE_BUFFER_SIZE,
                         &stCOP,sizeof(ATA_PASS_THROUGH_DIRECT)+READ_ATTRIBUTE_BUFFER_SIZE,
                         &dwRet,NULL);

最后Getlasterror返回1306.
