Failing Parity drive?

[samtrois]

I think I have a problem with my 3-4month old 8tb WD red parity drive. 
 

Have attached the SMART report, I believe an anomaly lies in  "197 Current Pending Sector" as that is highlighted yellow when viewed in unraid device attributes. 

 

Is this something I can fix, Or is this grounds for a replacement?

Got a replacement. Short/long test also failure in short time.

Not sure what that stuff you quoted means, and no I don't have a replacement.

Besides the failed SMART tests mentioned by Benson, disk has a failing now SMART attribute:

 

Vendor Specific SMART Attributes with Thresholds:
ID# ATTRIBUTE_NAME          FLAGS    VALUE WORST THRESH FAIL RAW_VALUE
  8 Seek_Time_Performance   P-S---   012   012   020    NOW  47

You need to replace it.

Would this type of failure be a call for warranty replacement? The drive was purchased in June

 

 Can I provide the SMART report to the shop and tell them the drive has failed XXXX on the test

[JorgeB]

Yes, a failing NOW SMART attribute is more than enough to ask for a warranty replacement.

I am resurrecting this post as I am still having troubles with this drive (purchased 5 months ago).

 

This drive used to be my parity drive, so the first thing I did was purchase another drive to replace it, and this has since been part of my array. It works fine for a time, then similar SMART warnings start to appear, and occasionally unRaid will crash/hang, and when I reboot the drive isn't showing up. 

 

This has happened several times, but it always seems to be alright with a rebuild, so i thought the problem was faulty power splitter cables or SATA cables. it's not powered from its own cable from the PSU, and have tried on both HBA cables and now it runs straight from the mobo SATA. So it happened again over the weekend, and I thought I may as well just try and return it. But low and behold, when plugged into their tester as a 'fresh' drive it passes the SMART test with flying colours. They offered to have it sent back to WD, but that could take up to 2 weeks, and I don't think I can wait that long. 

 

The "SMART Overall-health: FAILED " and unRaid hasn't been able to complete a SMART health-test for a while (and won't actually log the error reason?) 

 

What recourse do I have here, or how can i encourage this drive to fail properly.

BTW, it is the same drive "R6H1LS5Y", the issue was weak sector problem, that's why you got below founding again and again.

But I don't agree below, it is impossible insert the disk to another machine then all SMART resume normal ( from your pic, also no show any test have pass too )

You really have 2 option, replacement and wait for 2 weeks ( perfer as have warranty ). Another option was perform secure erase for whole disk, the purpose was let disk itself "mask" those weak sector, I have several those disk ( already no warranty ) which is the only way could fix and use again.

 

But perform secure erase need under command line and skill, you may make mistake and got trouble if you haven't those experience. So I don't recommend this way.

Yes, this is the exact same drive as the report posted in the first post.  The images are the current status of the drive. 

 

I really don't want to send it away for 2 weeks just to have them tell me its fine.
