Question Storage manager S.M.A.R.T. Test did not complete

NAS
2x DS1813+ , DS1019+
My log file indicated some bad block on a 3tb drive so i started up a SMART extended test last evening. At about 1am it was 90% complete. This morning it was still at 90% with no change over the next few hours.
My unit is a DS1813+ with DSM 6.2.2-24922 Update 4. System status shows healthy and all drives show healthy. The drive in question has a bad sector count of 4.

comments or suggestions?

thank you
 
The "90% complete" is an unresolved Synology bug.

Shutdown the NAS, pull the suspect drive and connect it to a PC via SATA/USB dock/cable and use your OEM diagnostic tool. For example...
  • Western Digital Data Lifeguard
  • Seagate SeaTools
  • Samsung HUTIL
  • Fujitsu HDD Diagnostic Tool
  • Hitachi Drive Fitness Test

idk if the Synology bug makes sense though.

I have 4x 4TB drives all running this same model and Firmware version, and the lower 3 were able to Complete the extended test fine, but Drive 1 hung at 90% on the extended test for LITERALLY months before we noticed it was still running and tried stopping it

Somewhat interestingly, the Extended test that was running from 4/16 - 9/07 still shows up as 4/16 in the Test History *sigh*

I have had the same issue but when I took the drive out and tested it in my testbed there were no issues with the drive. I am running DSM 7.0
 
Yeah, I'm showing 3 "bad" sectors in Synology-land on that drive, but getting very persistent read errors that make me wonder if there are more bad sectors that just aren't showing in the SMART Quick test - the Storage Manager didn't even show it as "warning" until I tried a desperate update to DSM 7.0 hoping it might have some newer tool/improvement

I need to just get over there and pull the drive and run it through the paces externally, just going to have to interrupt backups for an unknown amount of time to do it ugh - AND that still isn't a SOLUTION - just sidestepping the issue to hopefully track down these misbehaving sectors

Io errors are often caused by a bad connection, and not by disk errors. Therefore they may not show up during disk diagnose.
you might want to check if the disk is properly seated and its connections are ok.

You are absolutely right. I figured out that it was Snapshots taking up the space. Thanks!
