Greetings all!

I noticed there's quite a few threads on the subject but it appears that situations differ so I wanted to post my own findings in case someone could help. I noticed today an email from the script (posted here) showing something wrong with one of my drives. Here's the entire email:

Is this drive toast?

 

[NugentS]

No its not toast. But it is warning you about a potential issue.

What I would do is:
1. Get a new drive and replace da0
2. Run the WD diagnostics against the drive on another computer as a baseline.
3. Run badblocks or equivalent on the entire drive destrutively
4. Now run the WD Diags again - if it passes then keep the drive as a spare for the future

Actually, run a long SMART test on it first and post the result here

Sorry for the delay, here's the result of a long test:

Three failed SMART self-tests in a row? The drive's got one foot in the grave--time to replace it.

 

[NugentS]

All on the same LBA.
Definately replace it - but don't throw it away. Badblocks it thoroughly whilst NOT in the array, then log test it and see what happens.

Unfortunately I don't have another computer handy to run badblocks. Is there an alternative? Thank you for your help this far.

HDDScan - FREE HDD and SSD Test Diagnostics Software

HDDScan is a Free test tool for hard disk drives, USB flash, RAID volumes and SSD drives. The utility can check your disk for bad blocks in various test modes.

It isn't as thorough - but will probably do the job. From memory you want to use the erase entire disk function

If you have another port available on the NAS you could use that - just make sure you target the correct drive. Also do it a tmux / screen session and not a basic shell, or god forbid the TrueNAS menu shell.
