I have found the smart reporting of seagate barracuda drives to be flaky at
best. (but I always back up and monitor as well) I have 4 spinning in 2 dmraid
arrays on a backup server, and sometimes it just throws errors. (it has done
that for years) Drive info is:

There have been a number of firmware changes/updates for seagate drives over the
past 3 years and several "bad runs" of disks. Check the seagate support site and
make sure you have the latest firmware for your drive. I have had the bad sector
errors - sometimes a true failure, sometimes not. Just backup, monitor and if
you continue to get the errors, drop of $50 on a new 1T drive.
