[QUOTE="Lifeisabeach, post: 1579550, member: 38864"] I have to disagree with this. Onyx relies on the short SMART testing that reports using the manufacturer's guidelines. Everything I've read about SMART testing is that if you fail a SMART test using the "short" test, your drive is in critical condition and about to fail at any moment. Doing a "long" test using more advanced testing tools will give a clearer picture of a drive's health. You can easily pass a short test, but your drive still not "quite" on the edge of death to trigger a fail yet already exhibiting issues. Even the long test isn't foolproof. [URL="http://www.mac-forums.com/forums/apple-desktops/302423-grrrr-hdd-crashed.html"]I had a drive crash on me last year[/URL] and it even passed the long test while it was doing nothing but thrash and grind.
