I'd refactor the steps this way: 1. log messages to a buffer 2. periodically flush the buffer to the flash drive, if it's available The "periodically" part could be accomplished with a thread or scheduled delays, however suits your application. It might not be a final if you need to log messages promptly, but that's how I'd begin. Carl Banks -- http://mail.python.org/mailman/listinfo/python-list
