Since smartd monitors the health of your hard drives, it is telling you of bad sectors on it. I don't know how many bad sectors is OK, but this could be a sign that the hard drive is failing. It could continue to work for a long time, or it could fail tomorrow. I would get a replacement drive and back up all of the important data to it.

smartctl -a /dev/sdx

See man smartctl for info. Bad sectors do not necessarily mean your disk is going bad soon. Keep an eye on it but don't panic.
