A google using
manufacturer smart site::centos.org
should lead to a couple good threads on this list. I'd cite the recent
related, but I'm short of time ATM.
As long as you only see one, or very few, errors and very limited growth
in the number, no worry IMO. However, to confirm this, use smartctl to
get a full check and logging done. Then use it to review the logs.
I've got one that has had 2 errors for more than 6 months now. Used the
manufacturer tools, it got repaired, only one occurrence since.
