I believe that 'emergency' spindown (on power fail) is different from regular spindown, and that emergency spindown damages the disk more. But perhaps park + power fail is similar to regular spindown? (Is park command normally supported on modern disks? IIRC hdaps people had issues with not all disks supporting it?) -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
