"SMART is not enabled" in disks, according to smartctl it is

[wvengen]

When opening gnome-disks and selecting my internal hard disk, it tells me that "SMART is not enabled". After enabling it with smartctl, I could see its values using the command-line. Still gnome-disks keeps telling me that "SMART is not enabled", even after several reboots.

$ sudo smartctl -d sat -i /dev/sda
