c - 如何通过c语言获取内部SATA智能状态

Question

我正在尝试在 Windows 上获取内部 sata 驱动器的温度，到目前为止，我已成功获取驱动器 ID，它的所有信息，如存储容量、序列号。，型号等，但无法获得其温度详细信息，尽管我的 sata 驱动器通过工具（水晶信息）提供温度。我也通过文件来解决这个问题，但没有得到太多。

这是将命令发送到磁盘的示例代码

                {

    if (life > 10)

    }
    else if (life == 10)
    {
        disk_info.health = DISK_STATUS_CAUTION;
    }
    else if (life < 10)
    {
        disk_info.health = DISK_STATUS_BAD;
    }
    else
    {
        disk_info.health = DISK_STATUS_UNKNOWN;
    }
    //_aligned_free(identifyResp);

    return;

在我的情况下，“DeviceIoControl”函数之后的计数始终为零，这意味着缓冲区未填充。disk_info 只是收集与驱动器相关的所有详细信息的结构。看到日志后，我发现“DeviceIoControl”返回错误代码 1117。请帮我解决这个问题
