So, first of all just about all my hard drives are in a RAID at this point, so I have a higher tolerance for issues. If a drive is under warranty I'll usually try to see if they will RMA it. More often than not they will, and in that case there is really no reason not to. I'll do advance shipping and replace the drive before sending the old one back so that I mostly have redundancy the whole time. If it isn't under warranty then I'll scrub it and see what happens. I'll of course do SMART self-tests, but usually an error like this won't actually clear until you overwrite the offline sector so that the drive can reallocate it. A RAID scrub/resilver/etc will overwrite the sector with the correct contents which will allow this to happen. (Otherwise there is no way for the drive to recover - if it knew what was stored there it wouldn't have an error in the first place.) If an error comes back then I'll replace the drive. My drives are pretty large at this point so I don't like keeping unreliable drives around. It just increases the risk of double failures, given that a large hard drive can take more than a day to replace. Write speeds just don't keep pace with capacities. I do have offline backups but I shudder at the thought of how long one of those would take to restore. -- Rich
