Help with HD smartctl notices


I have replaced an old hard drive with a brand new one and just finished running smartctl long test. What does the “Remaining 90%” mean:

Also, is this brand-new hard drive a bad hard drive based on the status saying “Completed: read failure” (see full report below):

If Selective self-test is pending on power-up, resume after 0 minute delay.

It means the drive failed its self test with 90% of the test remaining.

Ie just over 10% completed.

Which means the drive is DOA and should be returned.

Probably. You can try the self-test again in case your result was a fluke, but that’s likely what it means.

Infant mortality.

RMA it immediately for a replacement (or refund?)

Please use only lowercase letters, and put a period between them. (i.e,)

Otherwise, I’ll have to assume you’re attempting to write in French… le very poorly.

Thank you all! Unfortunately, this HD is out of warranty as we purchased them a while ago as backups:

I’ve re-run another smartctl long test to see if it reports the same issue. We have 5 more of these drives brand-new so I’ll try swapping this one with another.

Is it ok to run smartctl long tests on all of the pool HDs (8 HHD) at the same time? Or will that harm something?

Much appreciate your help!


I’ve been doing it for the last several years, once a week. Try to schedule the long self-tests so a scrub isn’t happening at the same time, but otherwise no problem.

I thought you alluded to it being “brand new”?

It is, with only four power-on-hours as shown in the SMART data. But it’s been sitting unused for a few years, apparently.

The better course of action, if they were being kept as spares, would have been to burn-in and test them all at the outset, and then keep them as cold spares. But that’s easy to say in hindsight.

Oh my.

I have two spare drives waiting to be used as “replacements” when the (eventual) time arrives, but I will occasionally plug them in, run a long test, and then put them back into a storage box.

Or it hit 65336 hours.

I think my last drive that did that failed the next smart test too.

Try an extended test again. If it fails, replace the drive. Otherwise chalk it up to the 16 bit limit of power on hours.

Edit: “brand new drive”

This could be a divine intervention, since the WD60EFAX is an SMR drive. :wink:

@stevewest15 Are the other drives also WD60EFAX? :flushed:

Why I use a hot spare. At least I find out when the smart tests begin to fail.

And whenever I replace a drive, I use the hot spare and then the new drive (maybe an rma) becomes the new hot spare after burnin

I haven’t as yet felt the need for a hot spare. But if I did, I’d have to give serious thought to whether RAIDZ2 + hotspare was a better configuration than RAIDZ3. Because I’m not sure it is.

This is true, but mirrors + a hotspare is an easy decision :wink:

If I was running raidz2 I’d have 2 or 3 vdevs. A hotspare would probably make sense in that case too.

Yes, all of the spare drives are WD60EFAX. Should I stay away from these WD Red Plus drives?

The other drives in the Pool are all Model: WDC WD40EFRX-68N. Any recommendations on what WD drive I can pickup from Amazon that would be recommended if the WD60EFAX is not recommended?



“EFAX” are not Red Plus. Those are Red.

Yes, for ZFS, they should be avoided.

Those are fine. They are indeed Red Plus.

Stay away from “EFAX” if you want to stick with WD.
