In case you want to use it for copy protection and you need it to return always the same serial on one computer  of course as far as first hdd or ssd is not changed  I would recommend code below  For ManagementClass you need to add reference to System Management  P S  Without  InterfaceType  and  DeviceID  check that method can return serial of random disk or serial of USB flash drive which connected to pc right now       public static string GetSerial                 try                       var mc   new ManagementClass  Win32 DiskDrive                var moc   mc GetInstances                var res   string Empty              var resList   new List lt string gt  moc Count                foreach  ManagementObject mo in moc                                try                                       if  mo  InterfaceType   ToString   Replace      string Empty      USB                                                 continue                                                          catch                                                      try                                       res   mo  SerialNumber   ToString   Replace      string Empty                       resList Add res                       if  mo  DeviceID   ToString   Replace      string Empty  Contains  0                                                  if   string IsNullOrWhiteSpace res                                                         return res                                                                                    catch                                                                res   resList 0               if   string IsNullOrWhiteSpace res                                 return res                                  catch                              return string Empty

The best way I found is  download a dll from here  Then  add the dll to your project   Then  add code    DllImportAttribute  HardwareIDExtractorC dll    public static extern String GetIDESerialNumber byte DriveNumber     Then  call the hard disk ID from where you need it  GetIDESerialNumber 0  Replace      string Empty     Note  go to properties of the dll in explorer and set  Build action  to  Embedded Resource
