I had another look at the logging package. The class TimedRotatingFileHandler within the initialisation method uses the FileHandler.__init__. Whereas the FileHandler.__init__ method opens the stream in the 'append' mode (mode='a'). If the flash drive is not available while you start the script, which equals that you can't open a file in the append mode, then the TimedRotatingFileHandler (or FileHandler) fails. In my opinion the only way to go through this is to use two different handlers and once the flash drive is available then start to use the FileHandler. Still not sure if I want to use separate thread for checking the flash drive availability. Probably I need to build it this way.
