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更多磁盘的健康状况。

我可以使用ATAPI的WMI界面获取SMART数据，然后链接：http://wutils.com/wmi/root/wmi/msstoragedriver_atapismartdata/

但我不知道如何执行SMART Self-Test。有什么方法可以通过使用C＃来实现吗？

Answer 1

我试图做同样的事情，发现可以通过WMI开始测试。查看MSStorageDriver_FailurePredictFunction命名空间下的WMI类ROOT\WMI。该类有几种不同的方法可供使用。其中之一是ExecuteSelfTest方法。请看我使用WMI代码创建器（WMICodeCreator）

创建的示例

            try
            {
                ManagementObject classInstance = 
                    new ManagementObject("root\\WMI", 
                    "MSStorageDriver_FailurePredictFunction.InstanceName='SCSI\Disk&Ven_Hitachi&Prod_HDS721010CLA632\4&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);
            }

您必须将上面代码中的InstanceName更改为您的diskname。我还发现，"Subcommand"参数是决定实际开始测试的因素。如果值为1，则启动Short Self-test。如果值为2，则启动Extended Self-test。

作为输出参数，您可以收到这三个值中的一个['0', '1', '2'] 虽然0代表'Successful Completion'，1代表'Captive Mode Required'而2代表'Unsuccessful Completion'。源（FailurePredictFunction）

感谢LuXxn，

我已经成为您的导游，但我只能成功执行Short Selft-test和Extended Selft-test。甚至我的硬盘也支持在离线模式下立即测试SMART Conveyance自检例程（值= 03h）。但它总是返回代码是1＆＃39;需要的俘获模式＆＃39;。你知道怎么执行这个测试吗？

我遵循ATA / ATAPI注释设置ACS-3规范[表127，http://www.t13.org/Documents/UploadedDocuments/docs2013/d2161r5-ATAATAPI_Command_Set_-_3.pdf]以确切知道输入参数以执行SMART Selft-test

inParams [＆＃34;子命令＆＃34;] =？值;

要知道我的硬盘可以支持在离线模式下执行SMART传输自检，我发送了SMART命令以获取OfflineCollectCapability的值，然后返回值为0x73并遵循ATA / ATAPI注释设置ACS-3规范[表133， http://www.t13.org/Documents/UploadedDocuments/docs2013/d2161r5-ATAATAPI_Command_Set_-_3.pdf]
