The Win32_Volume documentation with the Chkdsk method you cite indicates it is a legacy API, but has not yet been deprecated so you could use it.
The current Storage Management API equivalent is MSFT_Volume. It has a Diagnose method that looks to perform similar functionality.
To execute a method on a WMI object via COM you need to obtain a pointer to a WbemServices object. It has an ExecMethod method you can invoke that does what you want for WMI classes. The code to retrieve this object is in JNA's WbemcliUtil class as a return type from the connectServer() method.
You will also need the full path to the Class Object; this is available by querying WMI for the __PATH, similarly to how you'd query any other field. That same WbemcliUtil class has a WmiQuery class you can instantiate to execute the query, collecting that path from the WmiResult. See the JNA test classes for examples on using these.
Finally, you can execute the WMI method. The code below will accomplish it for String properties, e.g., the MSFT_StorageDiagnoseResult object you'd get from MSFT_Volume's Diagnose method. You'd have to treat other return types differently.
/**
* Convenience method for executing WMI methods without any input parameters
*
* @param svc
* The WbemServices object
* @param clsObj
* The full path to the class object to execute (result of WMI
* "__PATH" query)
* @param method
* The name of the method to execute
* @param properties
* One or more properties returned as a result of the query
* @return An array of the properties returned from the method
*/
private static String[] execMethod(WbemServices svc, String clsObj, String method, String... properties) {
List<String> result = new ArrayList<>();
PointerByReference ppOutParams = new PointerByReference();
HRESULT hres = svc.ExecMethod(new BSTR(clsObj), new BSTR(method), new NativeLong(0L), null, null, ppOutParams,
null);
if (COMUtils.FAILED(hres)) {
return new String[0];
}
WbemClassObject obj = new WbemClassObject(ppOutParams.getValue());
VARIANT.ByReference vtProp = new VARIANT.ByReference();
for (String prop : properties) {
hres = obj.Get(new BSTR(prop), new NativeLong(0L), vtProp, null, null);
if (!COMUtils.FAILED(hres)) {
result.add(vtProp.getValue() == null ? "" : vtProp.stringValue());
}
}
obj.Release();
return result.toArray(new String[result.size()]);
}
A more complete example of querying a COM object, where I extracted the above code, is in this utility class which queries the GetOwner() and GetOwnerSid() methods on the Win32_Process object. It's legacy code from before I contributed the WbemCli class to JNA, so you'll have to adapt some of it, but it should be a good starting point.
