Could not get yours to work.<br />

This works for me: @&quot;SELECT * FROM Win32_LogicalDisk where DeviceID = 'C:'&quot;);

I'm working with the following typical example of WMI hardware searching, but only need the FIRST harddrive instead of the whole array. The following code is all I can find.<br />
<br />
ManagementClass mc = new ManagementClass(&quot;Win32_Phy<wbr />sicalMedia<wbr />&quot;);<br />

I'm working with the following typical example of WMI hardware searching, but only need the FIRST harddrive instead of the whole array. The following code is all I can find.

ManagementClass mc = new ManagementClass("Win32_PhysicalMedia");
            foreach (ManagementObject mo in mc.GetInstances())
            {
                if (mo["SerialNumber"] != null)
                    data.DriveSerialNumbers.Add(mo["SerialNumber"].ToString());
            }

ManagementClass Get First Harddrive Only?

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
