Unraid showing failed drive as healthy in dashboard

[lezo]

Yesterday I put some drives in my unraid server, and I left copying some data to them overnight. This morning I found that one of them was showing i/o errors in dmesg.

On the dashboard in unraid it still says the drive is healthy - clicking on it and scrolling down to the 'Identity' section of the device page it shows something different to all my other healthy drives -

 

"SMART health status:DATA"

 

This led me to run smartctl on the device, output posted below.

Is this possibly a bug in the way which unraid interprets the output from smartctl for the dashboard, or some sort of configuration issue on my end?

Knowing that the drive knew itself that failure was imminent, I'd wish to be able to see that reflected in the dashboard.

SMART section in the GUI only works correctly with SATA devices, with SAS some parts don't work correctly since SMART reports are very different, SMART tests also don't work.
