I am writing an application based on .NET that checks the heath of a disk or more disks in a system.
I can use the WMI interface for ATAPI to get at the SMART data, followed by link: http://wutils.com/wmi/root/wmi/msstoragedriver_atapismartdata/
But i don't know how to execute SMART Self-Test. Is there any ways to do it by using C#?
I was trying to do the same and found out that it is possible to start the test via WMI. Have a look at the WMI class MSStorageDriver_FailurePredictFunction under the ROOT\WMI namespace. The class has several different methods you can use. One of them is the ExecuteSelfTest method.
Look at this example I created with the WMI Code Creator(WMICodeCreator)
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);
}
You have to change the InstanceName in the code above to your diskname. What I also found out is that the "Subcommand" parameter is the factor which determines what test you actually start.
If the value is 1 you start the Short Self-test.
If the value is 2 you start the Extended Self-test.
As an output Parameter you can receive one of those three values ['0', '1', '2']
while 0 stands for 'Successful Completion' , 1 stands for 'Captive Mode Required' and 2 stands for 'Unsuccessful Completion'. Source(FailurePredictFunction)
Thanks LuXxn,
I already succeed as your guide, but i only succeed to execute Short Selft-test and Extended Selft-test. Even my Hard-disk also supports to test SMART Conveyance self-test routine immediately in off-line mode (value = 03h). But it always return code is 1 'Captive Mode Required'. Do you know how to execute this test ?
I followed ATA/ATAPI Comment Set ACS-3 specification [Table 127, http://www.t13.org/Documents/UploadedDocuments/docs2013/d2161r5-ATAATAPI_Command_Set_-_3.pdf] to know exactly input parameters to excute SMART Selft-test
inParams["Subcommand"] = ?value;

To know my hard-disk can support execute SMART conveyance selftest in offline mode, I sent S.M.A.R.T command to get the value of OfflineCollectCapability, then return value is 0x73 and followed ATA/ATAPI Comment Set ACS-3 specification [Table 133, http://www.t13.org/Documents/UploadedDocuments/docs2013/d2161r5-ATAATAPI_Command_Set_-_3.pdf]
