Hi Michael and Chuck,

not sure, whether this is a problem, but I get a surprising result for my 6GB
WD-Red SATA drives:

The last two rows re-use attribute IDs seen before, are out of order and do
not report the values I'd expect. These rows are missing from the smartctl -a
output:

Should the last two lines of smart output be omitted (e.g. by filtering
based on their flag value?).

BTW: an option to print fixed width columns with headings or CSV format
with header line (or e.g. JSON) might be useful.

And: While the first three columns are documented, the -t output is not.
