Hello, it took me a while to figure it out how this class works. Here is a sample in Managed C++:

ManagementObjectCollection ^c = query("Win32\_DiskDrivePhysicalMedia");
for each(ManagementObject ^o in c)
{
	DeviceInfo ^device = gcnew DeviceInfo();
	ManagementObject ^media = gcnew ManagementObject(o\["Antecedent"\]->ToString());
	ManagementObject ^disk = gcnew ManagementObject(o\["Dependent"\]->ToString());
	Object ^temp = disk\["Manufacturer"\];
	if(temp) device->manufacturer = temp->ToString();
	temp = disk\["Model"\];
	if(temp) device->model = temp->ToString();
	temp = media\["SerialNumber"\];
	if(temp) device->serial = temp->ToString();
	
	list\_->Add(device);
}

The class Win32_DiskDrivePhysicalMedia only contains references to the Physical Media and Disk Drive objects. You must, then, instatiate both objects to access their properties individually. Regards, Paulo
