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=20 be failing and be beyond the range of the drive's ability to cope, it=20 could raise an event and move the blocks used to another disk. This=20 could give another level of data protection rather than just simply=20 relying on multiple copies as current RAID schemes mostly do =2D-=20 Alan McKinnon alan dot mckinnon at gmail dot com -- gentoo-user@lists.gentoo.org mailing list
