That doesn't mean too much. SMART reports a lot of false negatives, to borrow a phrase.
Interesting. I'd always been told that smart status is super and it works more or less as you 'd expect. Is it generally useless then?

If SMART says your drive is failing it almost certainly is failing, so that's useful. But drives can fail silently without SMART noticing.

Google did some research into this. There's a summary at <http://arstechnica.com/news.ars/post/20070225-8917.html> but maybe the original article is worth a read too <Failure Trends in a Large Disk Drive Population>

Cheers,
