Option is grayed. Status in gnome-disk-utility package in Ubuntu: Invalid Bug description: gnome-disk-utility (show as "Disks" on the desktop environment running Unity) systematically does not acknowledge that disks have SMART capabilities when connected through a USB port; SMART capabilities are grayed. However, 'sudo smartctl -a /dev/<disk>' works fine. gnome- disks acknowledge SMART capabilities if the same disk is connected through a SATA port. Confirmed for Ubuntu 14.04 LTS Trusty Thar on 2016-01-26, gnome-disk- utility 3.10.0, udisks 2.1.3 (built against 2.1.3) by Hans Deragon. Original report --> In terminal it wasnt enabled but it was supported. I enabled it in 12.04 ubuntu in terminal. In 10.04 in terminal it shows its enabled but see screenshot in Disk utility it doesnt show SMART. PS. I formated using Disk utility using : Dont partition and in fdisk -l it doesnt show any partitions. Thats then showing all correctly?
