NOTES:
At the end of media patrol, always check the event log
to see if any error occurs during media patrol. If a
media error occurs, a message indicating the
occurrence of the error appears before the message
indicating that the media patrol has finished
successfully.
If a media patrol task has been scheduled, and if the
scheduled time comes while another media patrol task
is being performed, the scheduled media patrol is
skipped (not executed) for that time.
If a media patrol task has been scheduled, and if the
scheduled time comes while the power is off, the
media patrol task will start after the power is turned
on.
