Hey everyone,

 

I have a Seagate 4TB NAS drive, which I bought back in January, and has just been added to the array for about a week now (replacing an old 200GB drive).

 

Back in January, it precleared without any problems but since it's been added to the array I've encountered several SMART errors.

 

At first, current pending sector and offline uncorrectable values increased and threw SMART errors. They both increased to a max. value of 24.

 

After running an extensive SMART self-test those values returned to 0 but then I received reported uncorrect SMART errors. This value has increased to 2 now.

 

The status emails I receive from my unraid say Notice [TOWER] - array health report [FAIL] and Disk 6 - ST4000VN000-1H4168_Z304DKYE (sdn) - active 34 C (disk has read errors) [NOK].

Doesn't look good.

 

However, at the bottom of the disks' page under Identity it still says SMART overall-health: Passed.

 

Should/could I RMA this drive?

 

I have several Seagate NAS drives and this is the first one with which I've encountered SMART errors.

 

I've attached the SMART report, would be very much appreciated if someone could share their expertise.

 

Thanks!

Should/could I RMA this drive?

 

Yes.

 

9 Power_On_Hours          0x0032  097  097  000    Old_age  Always      -      3149

 

Error 2 occurred at disk power-on lifetime: 3142 hours (130 days + 22 hours)

  When the command that caused the error occurred, the device was active or idle.

 

  After command completion occurred, registers were:

  ER ST SC SN CL CH DH

  -- -- -- -- -- -- --

  40 51 00 ff ff ff 0f  Error: UNC at LBA = 0x0fffffff = 268435455

 

 

 

Thanks for you reply.

 

I've just finished another SMART extended self-test > Completed without error

 

I still have the reported uncorrectable value as a warning (value = 098, raw value = 2)

 

 

And the unRaid status mails still say the array has failed (same message as in my earlier post)

 

 

I'm just a bit afraid an RMA might not be accepted as SMART status is passed

 

 

Is there anything I can try to get rid of the array fail?

 

 

Or should I not bother any with any further troubleshooting and just ask for the RMA?

 

I've attached the new SMART report.

Post a screenshot of the array or the complete diagnostics.

Statistics from the dashboard

array devices

disk attributes

Rebooting will take care of the array errors, but I still wouldn't trust that disk, you should have no problem with the RMA even if SMART is ok, if the refurbished disk is any more reliable is another matter, in my experience they have at best a 50/50 chance of lasting more than a couple of months.

Thanks johnnie.black, I'll request an RMA and see what happens.
