"Our analysis identifies several parameters from the drive's self monitoring facility (SMART) that correlate highly with failures. Despite this high correlation, we conclude that models based on SMART parameters alone are unlikely to be useful for predicting individual drive failures. Surprisingly, we found that temperature and activity levels were much less correlated with drive failures than previously reported."
It's far from clear what's causing this; the site's PageRank is apparently fine. Attempts to contact Google have fallen on deaf ears and dumb autoresponders. The site was even recently redesigned in the hope of fixing the problem, with no luck so far. Is the world's most popular search engine really this broken, and how much money are people bringing in from knowing the black magic to work around it?
