Hi all,

Diagnostics zip attached.  Machine hasn't been rebooted, I've not done anything (like checking cables), scrutiny reports no errors on the disabled disk, and unraid is currently half way through a "Read-check".  I'd appreciate any comments, thoughts, ideas on this.

 

thanks

You should configure each of your WD RED disks to monitor SMART attributes 1 and 200. That one doesn't look good.

No read error, just the write error, which is not so common, I would replace/swap cables on that disk, if it happens again it's likely a disk problem.

thanks for your advice
