I don't see anything but smartd repeatedly warning you about the 1
pending sector.

As I said, it's annoying when a drive doesn't decremement its
pending sector count after remapping. If you can read the whole
drive then it certainly has been remapped (or was a transient error
that isn't "pending" any more).

None of the logs you presented show any error coming from the drive,
but then they won't as you've only selected logs from smartd. smartd
will complain about that 1 pending sector count until the end of
time unless:

- Drive just decides to clear it, or;

- You reconfigure smartd

All smartd is doing here is reading the attributes of the drive and
reporting them to you. It will never show you the actual error that
caused those attributes to change.

It's not my view as in my experience storage is one of the most
failure-prone parts of a computer, and an outage from non-redundant
storage typically annoys me more than making it redundant does.
That is in most cases really easy and cheap these days, so I do
regard going without it as living dangerously. Not always a good
cost-benefit trade off though, I grant you.

Thanks,
Andy
