I have a disk that shows 1 reallocated sector, would you put this disk that disk in an array?

 

It is a bit oldish, but SMART report looks ok as fas as I can tell. Or would you RMA it, which seems a bit troublesome nowadays here in Europe.

It depends on whom you ask. Some believe a stable low value is ok. I personally beleive 1 is 1 too many.

At least run it through a cycle of preclear to see if the value increases.

Personally I don't think there is anything wrong with a re-allocated sector. Modern drives are designed to reallocate any sectors that are buggered to an alternative location.   

 

I would start to worry however if you start getting pending sectors. These are sectors that are being used and can't be reallocated because they can't be read to reallocate elsewhere. Id say monitor the drive. You're good if you don't start getting Pending Sectors. If you do then I would replace the drive as soon as possible.

 

In summery I would say that a relatively small increase of reallocated sectors over time is not a reason in itself to replace a drive. If however this starts to get out of control (and increases start becoming more common) then I would take this as an indication of a drive becoming defective and would replace it.

 

For now though, I would say your drive is fine.

I usually don't replace a drive until it surpasses the smart threshold values. But then I am running dual parity on both my main and backup servers.  It's entirely up to what your comfort level is though.  For a few reallocated sectors I wouldn't bother.  Unless the drive is close to being out of warranty. Then i'd pull it and make sure I got a replacement before the warranty ran out.

I took that the OP was implying that the drive is not under warranty by suggesting it is old. However, your post and a re-read of the OP does suggest RMA is a possibility

 

If it Is not under warranty I'd follow the advice I gave initially. If it is under warranty, I second the advice given above and use this as a means to get it replaced.

It sustained 5 preclear runs without adding reallocated or pending sectors. It still has 8 months warranty left. I gonna add it to the array and keep an eye on it. If turnaround time of a RMA was within a week I would RMA it, but HGST nowadays takes more than 2 weeks.
