Parity and disk errors

[ItsMrMe]

My Parity has 415 found errors and one of my disks reports 16 errors in the main view.

 

But I fail to understand how I can detect what those errors are, if they are harmful and how to fix them. Could you help me?

 

Diagnostics are attached.

It's logged as a disk problem, run an extended SMART test on disk3.

[ItsMrMe]

It's running now, I'll update you when it's ready.

You may have to disable spindown on the disk to get it to complete. Will take several hours

The extended smart for disk 3 was without error. I do still see the 16 errors in the main tab.

ID# ATTRIBUTE_NAME          FLAGS    VALUE WORST THRESH FAIL RAW_VALUE
  1 Raw_Read_Error_Rate     POSR-K   200   200   051    -    127
200 Multi_Zone_Error_Rate   ---R--   200   200   000    -    16

This does not look good for a WD drive.

 

Attributes 1 and 200 should ideally always be at 0 for WD drive.

You should adjust SMART attribute notifications for each drive to include those attributes.

 

If it was me, I would replace the drive.

Disk is OK for now, but like mentioned it doesn't look very good, it will likely fail again in the near future, up to you if you want to give it another shot or replace now.

[ItsMrMe]

I will replace the disk. If I do this, will the parity errors be fixed?

 

Thanks for your help so far, you're reacting so quickly!

[JorgeB]

Parity sync errors were immediately after the disk read errors, so yes, replacing it should fix that, assuming parity was 100% in sync.
