I think this is at the heart of my problem.  I do include a 
RegisterDeviceNotification() at initialisation but I'm not 100% sure what I 
should be registering for.  My code includes:

HDEVNOTIFY hDevNotify;
DEV_BROADCAST_DEVICEINTERFACE NotificationFilter;

memset(&NotificationFilter, 0, sizeof(NotificationFilter));

NotificationFilter.dbcc_size = sizeof(DEV_BROADCAST_DEVICEINTERFACE);
NotificationFilter.dbcc_devicetype = DBT_DEVTYP_DEVICEINTERFACE;
NotificationFilter.dbcc_classguid = GUID_DEVCLASS_DISKDRIVE;

hDevNotify = RegisterDeviceNotification( Application->Handle,
                                                &NotificationFilter,
                                                DEVICE_NOTIFY_WINDOW_HANDLE);

Though this doesn't make any difference.  I can comment it out and still get 
exactly the same messages arriving.  Maybe I should be registering 
DBT_DEVTYP_VOLUME - though since these cards are not FAT or NTFS formatted I 
don't know if that would work?

Thanks,
