Description

On 11.1-U5, I have identified a drive that is not compatible with smartd (usb drive).

If I go into View Disks, under Storage and check the "Enable S.M.A.R.T." checkbox, I receive an error message in the GUI that states "The service failed to restart.". I have attached a screenshot labelled "enabling_smart.png" showing the message.

This is expected behavior. If I go back into the webUI and UNCHECK the "Enable S.M.A.R.T." checkbox I receive the same "The service failed to restart" message in the webUI. I have attached a screenshot to this ticket laballed "disabling_smart.png" showing this message.
Even though after disabling SMART for the USB drive, the smartd service starts up as usual. The cli shows the smartd process running as normal.
