Brand new NAS drive with sector errors.

[shadex]

I just bought WD NAS HDD on Newegg: SMART reading indicate that HDD has 3100 unreadable sector. It's brand new :\. Should I send it back? See pix below:

This seems to answer my question:

SOLVED - Pending sector

Hi everyone, For a full week now my server has been warning me of an error concerning one of my drives. Apparently one of them has "1 currently unreadable (pending) sector". I had to look up what it actually meant, from what I understand now it is a sector which has not been reallocated yet and...

The drive may be fine, but it seems unusual. What is the model number of the drive?

 

[Davvo]

Run a long smart test, then paste the output of smartctl –a /dev/ada1 and smartctl –a /dev/ada2 between [CODE][/CODE] tags, however it seems strange that both disks are experiencing the same error. Something is fishy.
Also, this could be useful.

UPDATE: 22 September 2018 - Added Drive Data Refreshing UPDATE: 2 April 2017 - Added support for FreeNAS Corral (FreeNAS 10 and beyond) UPDATE: 1 November 2020 - Added ID 1 and 7 description for Seagate drives at bottom of Appendix B This guide...

Anyway, a bad sector should be enough for a RMA.

 

[Redcoat]

Shoot - I didn't notice there were two drives with similar reports - I was wondering of the OP has an SMR drive and was going to get that issue out pof the way before suggesting that he test and run bad blocks ...

Standard red (SMA drive I guess).

Yeah. Doing that right now. Sigh. I guess going SSD is even more attractive than HDD.

 

[Redcoat]

Standard red (SMA drive I guess).

Well, SMR drives are known problematical and not recommended for use with TrueNAS, so I suggest that you return that drive irrespective and get a CMR drive - if you want to go with HD Reds, get a Red+ which will be CMR - look at the listing in the resource here at https://www.truenas.com/community/resources/list-of-known-smr-drives.141/ for confirmation.

Anyway, please report the results of your long tests here in code tags as suggsted by Davvo - also better tell us about the rest of your hardware so that you can get some suggestions about what may be going on overall.

 

[Davvo]

SSDs often die without crying for help, HDDs warn you. Plus, they are cheaper per TB.
You were just unlucky to not notice the warnings in the forum and picked the wrong type.
It happens

WD NAS NSA STANDARD looks fine:

That's all I need to know. I'll send it back tmw.

Well, SMR drives are known problematical and not recommended for use with TrueNAS, so I suggest that you return that drive irrespective and get a CMR drive - if you want to go with HD Reds, get a Red+ which will be CMR - look at the listing in the resource here at https://www.truenas.com/community/resources/list-of-known-smr-drives.141/ for confirmation.

Anyway, please report the results of your long tests here in code tags as suggsted by Davvo - also better tell us about the rest of your hardware so that you can get some suggestions about what may be going on overall.

The test I performed was selected for long test.

The test I performed was selected for long test.

Yes, thanks. I read it.
So you’re returning the WD red / good move!
If the HGST were mine, I’d run bad blocks on it. Perhaps someone with specific HGST experience will chip in with other advice here?
It’s not clear if there’s something else going on with your system. Please give us a full description of your hardware and advise your Truenas version.

 

[Davvo]

To me the HGST looks like it's dying, but I have no experience with them.
The WD seems fine, but as @Redcoat said you want to send it back and use a CMR if you can.
SMR will cause you nightmares while resilvering.

Also, suggested reading:

Hard Drive Burn-in Testing

@jgreco did a nice system build/test/burn-in guide here, but I (and many others) found the details a bit lacking in the hard drive section. He mentions S.M.A.R.T. tests, but doesn't go over how to run them, or how to view the results, etc. and...
