Running UnRaid 6.3.5 for two days now since upgrading from 6.3.4 and I recently received a WebGui notification that stated:

 

    UnRaid Disk 1 SMART health [198]: 24-06-2017 1:51 Warning - offline uncorrectable 1 WDC_WD20EARS-00MVWB0_WD-WMAZA4052027 (sdd)

  

The WebGui Dashboard is showing an Array Status of Disk 1 with an orange triangle that has a context menu that states: 

   Reallocated sector count: 2

   Current pending sector: 1323

   Offline uncorrectable: 1

   Click for context menu

 

However, Disk 1 status from the main array page is still showing a green status with reads and writes, but no errors.

 

Disk 1 is a Western Digital drive that is 6 years old, do I need to replace it??

 

My system hardware specs/plugins-list, some screen shots to accompany my words above, and the SMART Diagnostics file for Disk 1 are attached in the zip file.

 

Thanks for any advice/help.

With 1323 pending sectors on a six year old disk, I would have already placed an order for a replacement! 

I have a replacement. I thought that "Current Pending Sector" since it was singular just meant that a single sector, number 1323, was pending.

Nope - it means that the drive has detected 1323 sectors that it has had difficulty accessing, and on the next write to those sectors, it would plan to realllocate the sector and map in a spare.

 

The absolute number is not that important, but once a drive starts having pending sectors and reallocated sectors, it means that the disk is failing, and time to replace it.

OK, thanks all for the advice, replace I will.
