Not errors "per se". It's a report of the disk activity.

^^^^^^^^^^^^^^^^^^^
That is important. It means your disk is not dying "right now" :-)

The data of the above table is also important. Unless you see "pre-fail"
attributes increasing from time to time, you should not worry (needless
to say that keeping a good backup is a must on these days, regardless the
healthy status of the disks).

Read that as "logs events", not warnings. New hard disks record the events
and try to correct the errors in real time (i.e., bad sectors are remapped
whenever possible).

There are some "how to read smartcl results" articles there. For example:
Linux Harddisk Monitoring with SmartMonTools (smartctl)
http://www.captain.at/howto-linux-smartmontools-smartctl.php
Monitoring Hard Disks with SMART
http://www.linuxjournal.com/magazine/monitoring-hard-disks-smart
BTW, I keep smartmontools daemon running and monitoring the disks status.
