  ManagementClass mc = new ManagementClass("Win32_Volume");
            ManagementObjectCollection moc =mc.GetInstances();
           
            if(moc.Count!=0)
            {  
           try{
           
            foreach (ManagementObject mo in moc)

                    if (mo["DriveType"].ToString() == "2")
                       {
                            Console.WriteLine(mo["Drivetype"].ToString());
