I bought these drives something like 3 odd years ago or so and although I fully understand these drives are only for backup proposes only, which is what I do. I sometimes, quite often, on a weekly basis upload gigabytes of data to an FTP server from one of the drives and sometimes watch movies off of it with the family gathered round.

Take a look at these readings.

Seagate's raw SMART values are counterintuitive. They represent sector counts and seek counts, not error counts. In fact your drive has recorded 0 seek errors.
