Larry,

Runnig the code 

EventHandferRef myHandler;

installEventHandler(void)
{
  EventTypeSpec kEvent[] =
  {
      {kEventClassVolume, kEventVolumeMounted},
      {kEventClassVolume, kEventVolumeUnmounted}
  };


  InstallEvenHandler(GetEventMonitorTarget(),MonitorHandler,
   GetEventTypeCount(kEvents)), kEvents,
   0, &myHandler);

  RunApplicationEventLoop();

} 


static OSStatus 
MonitorHandler( EventHandlerCallRef inCaller,
       EventRef inEvent, void* inRefcon )
{
 FSVolumeRefNum volRefNum;

 // get the event class
 switch ( GetEventClass( inEvent ) )
 {
  case kEventClassVolume:
 
  switch ( GetEventKind( inEvent ) )
  {
  case kEventVolumeMounted:
  case kEventVolumeUnmounted:
 
  GetEventParameter(
    inEvent,         
    typeFSVolumeRefNum,
    kEventParamDirectObject
    NULL,   
    sizeof(FSVolumeRefNum),
    NULL, 
    &volRefNum);

  break;
