Recently I had what I think was a powersupply problem which was causing disks to randomly go offline.  I moved the disks to a different power rail and it seems to almost fix the issue.  I say that because disk 1 is showing as disabled and the contents are emulated.  I downloaded the smart report and it shows it as passed but the disk still is disabled.  I have attached the diagnostic log and the smart report.  Any ideas how to reenable the disk?

 

Thanks,

 

David

this is all covered here in the online documentation that can be accessed via the ‘Manual’ link at the bottom of the Unraid GUI.

Diags are after rebooting so we can't see what happened but SMART report passed if basically meaningless, there's a pending sector and no SMART tests logged, you should at least run an extended SMART test, if it passes you can rebuild on top.

I just ran another short and extended test and got this, so maybe the disk is bad.

It is.

A full disk write might fix it, but if it does it's difficult to say for how long.
