I'd say you are overly cautious on this. Yes there are drives for which one reallocated sector is a sign of the coming avalanche of them, but then there are also ones (e.g. my Hitachi 2TB) which work for years, over than period develop 3-5-7 reallocated sectors, and THAT'S IT, they just continue to work. And if there's an unreadable sector on rebuild as a drive found its 8th bad sector after 3 more years of perfect operation, that's not a problem either, because the setup they run in, is RAID6. (Not to compensate for this, but I wouldn't be running a 8-10 drive RAID5 in any case). -- With respect, Roman -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
