如何执行智能自检

Question

我正在编写一个基于 .NET 的应用程序，用于检查系统中磁盘或多个磁盘的健康状况。

我可以使用 ATAPI 的 WMI 接口来获取 SMART 数据，后跟链接：http://wutils.com/wmi/root/wmi/msstoragedriver_atapismartdata/

但我不知道如何执行智能自检。有什么方法可以使用 C# 来做到这一点吗？

Answer 1

我试图做同样的事情，发现可以通过 WMI 开始测试。查看ROOTWMI命名空间下的 WMI 类MSStorageDriver_FailurePredictFunction。该类有几种不同的方法可以使用。其中之一是ExecuteSelfTest方法。 看看我用WMI Code Creator(WMICodeCreator(创建的这个例子

try
{
ManagementObject classInstance = 
new ManagementObject("root\WMI", 
"MSStorageDriver_FailurePredictFunction.InstanceName='SCSIDisk&Ven_Hitachi&Prod_HDS721010CLA6324&7d4adf0&0&010000_0'",
null);
// Obtain in-parameters for the method
ManagementBaseObject inParams = 
classInstance.GetMethodParameters("ExecuteSelfTest");
// Add the input parameters.
inParams["Subcommand"] =  1;
// Execute the method and obtain the return values.
ManagementBaseObject outParams = 
classInstance.InvokeMethod("ExecuteSelfTest", inParams, null);
// List outParams
Console.WriteLine("Out parameters:");
Console.WriteLine("ReturnCode: " + outParams["ReturnCode"]);
}
catch(ManagementException err)
{
MessageBox.Show("An error occurred while trying to execute the WMI method: " + err.Message);
}

您必须将上述代码中的实例名称更改为磁盘名称。我还发现，"Subcommand"参数是决定您实际开始什么测试的因素。 如果值1则启动Short Self-test。 如果值2则启动Extended Self-test。

作为输出参数，您可以接收这三个值之一['0', '1', '2']0代表'Successful Completion'，1代表'Captive Mode Required'，2代表'Unsuccessful Completion'。源(故障预测函数(

谢谢 LuXxn，

我已经成功地作为您的指南，但我只能成功执行简短的自我测试和扩展的自我测试。甚至我的硬盘也支持在离线模式下立即测试SMART Transportance自检程序(值= 03h(。但它始终返回代码为 1"需要捕获模式"。您知道如何执行此测试吗？

我遵循了 ATA/ATAPI 注释集 ACS-3 规范 [表 127，http://www.t13.org/Documents/UploadedDocuments/docs2013/d2161r5-ATAATAPI_Command_Set_-_3.pdf] 来准确了解执行 SMART 自检的输入参数

inParams["Subcommand"] = ？value;

为了知道我的硬盘可以支持在离线模式下执行智能传送自检，我发送了 S.M.A.R.T 命令来获取离线收集功能的值，然后返回值0x73并遵循 ATA/ATAPI 注释集 ACS-3 规范 [表 133，http://www.t13.org/Documents/UploadedDocuments/docs2013/d2161r5-ATAATAPI_Command_Set_-_3.pdf]
