可移动硬盘物理序列号如何获得

Question

           ArrayList arr = new ArrayList();            string strQuery = "SELECT * From Win32_LogicalDisk";
            ManagementObjectSearcher query = new ManagementObjectSearcher(strQuery);
            ManagementObjectCollection queryCollection = query.Get();
            foreach (ManagementObject mo in queryCollection)
            {
                if (mo["DriveType"].ToString() == "2")
                {
                    arr.Add(mo["Name"].ToString());
                    string aaa = mo["SerialNumber"].ToString();
                    MessageBox.Show(aaa);
                    //MessageBox.Show(mo["Name"].ToString());
                    mo.
                }
            }我用上面的方法只可以获得可移动硬盘的名字("Name"),获得不了序列好("SerialNumber"). 请高手们指教指教指教!!!

try
            {
                ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia");
                String strHardDiskID = null;
                foreach (ManagementObject mo in searcher.Get())
                {
                    strHardDiskID = mo["SerialNumber"].ToString().Trim();
                    break;
                }
                MessageBox.Show(strHardDiskID);
            }
            catch
