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.
