So my data disk (Disk 1) shows up as faulty with the message " Device is disabled,contents emulated". The disk has passed the SMART test and it shows up as healthy.

I can also browse the files from that disk.

 

Not sure why unRaid thinks its faulty?

UnRAID will disable any disk (and stop using it) if a write to it fails.   Often this due to an external factor (e.g. cabling, power) and the disk itself is fine.   You need to rebuild the disk to remove the ‘disabled’ state.  If you think the disk is fine then you can rebuild back to the same drive to bring it back inline with the emulated state.

And next time grab the diags after the disk gets disabled and before rebooting, so we can see what happened.

Shoot I forgot to get logs before I rebooted to check cables. To rebuild, stop the array set disk to no device reboot then set the drive back I the slot?
