[CentOS] SMART errors

[Blake Hudson]

Smart attributes are categorized as age and others as pre-failure. 
Anything that generates an 'error' is a sign of a problem, and may show 
up under pre-fail.

I'd replace the drive if you need the server to be available. If 
availability is not your goal, just keep decent backups and replace the 
drive after it dies.
