# KN, 8 Apr 2017:
# Added minimum test durations because some devices don't return accurate values.
# Added code to clean up the log file, removing copyright notices, etc.
# No longer echo 'smartctl -t' output to log file as it imparts no useful information.
# Emit test results after tests instead of full 'smartctl -a' output.
# Emit full 'smartctl -x' output at the end of all testing.
# Minor changes to log output and formatting.
#
# KN, 12 May 2017:
# Added code to poll the disk and check for completed self-tests.
#
# As noted above, some disks don't report accurate values for the short and extended
# self-test intervals, sometimes by a significant amount. The original approach using
# 'fudge' factors wasn't reliable and the script would finish even though the SMART
# self-tests had not completed. The new polling code helps insure that this doesn't
# happen.
#
# Fixed code to work around annoying differences between sed's behavior on Linux and
# FreeBSD.
