Current pending sector = 1

[JakeBullet]

Hi all.

New to Unraid as of about 3 months ago. One of my disks was flagged with 'Current pending sector 1'  and 'Offline uncorrectable 1' 

I have done a search here on the forum and seen some posts with the same issues. 

 

So. Here is what I have done:

Ran the long extended smart test (log included) and it completed without errors.

Ran Parity check with do not write corrections to parity and I get:

 

Unraid Parity check: 03-02-2020 04:56 PM

Notice [HPNAS01] - Parity check finished (0 errors)
Duration: 7 hours, 31 minutes, 45 seconds. Average speed: 110.7 MB/s

 

I then Reboot.

 

So when I check the drive it is still showing 'Current pending sector 1'  and 'Offline uncorrectable 1'  

I have also written 50Gb of junk data just to that drive and no more errors have sprung up.

 

I this drive OK? Ideas? Thoughts?

Sometimes these are reported as false positives, if SMART long test passed disk is OK for now and you can acknowledged the current attribute value, bur disk is showing some warnings on SMART, you'll want to keep an eye on it.

I did see that and it is a 5 year old drive. But did the sector get remapped?

 

[JorgeB]

Can't say that, it either was remapped or it in use again without error, firmware should have cleared the pending sector, but it didn't, it's not that unusual, especially with WD drives.

[JakeBullet]

Yep, it is a WD Red. But I have got 5+ years out of it so I cannot complain. I will keep an eye on it. Thanks.

What are the results of a non-correcting parity check? Any other errors occur during that? 

 

Looks like you already did that...

Still Working fine. I even copied another 100Gb+ to it and no other errors.
