Which gives me an idea on where such a thing might be useful - RAID If SMART (or something conceptually similar) detects that a drive might be failing and be beyond the range of the drive's ability to cope, it could raise an event and move the blocks used to another disk. This could give another level of data protection rather than just simply relying on multiple copies as current RAID schemes mostly do -- Alan McKinnon alan dot mckinnon at gmail dot com -- gentoo-user@lists.gentoo.org mailing list
