Bug Description

Ubuntu's Power Management does not power off the hard drive unless you edit a file manually.

Having cleanly installed Ubuntu on my old (desktop) computer for a friend, the 2nd hard drive never powers off - despite going into the Power Management settings and ticking the option "Spin down hard disks when possible". There are 2 actual hard drives in the case; there's no confusion with partitions appearing as separate hard drives. One hard drive is IDE and the other is SATA.

The only way I could get the 2nd hard drive to switch off was to edit /etc/hdparm.conf and uncomment (remove the hash "#") from the line in that file which has the number 24 at the end (only one line had the number 24 at the end of it). Making that change in /etc/hdparm.conf - then saving that file and rebooting - definitely worked as when you access the 2nd drive after a few minutes, you hear it power on - you can clearly hear the sound of it powering on and then you can see the files on that drive. It also powers off again if left idle - which proves changing that file works, but the power saving option GUI does not work.

I had previously reported this bug and I remember being told there was an update to one of the files (hdparm.conf I think?), but that bug report was closed. Please reconsider this bug report as it pertains to the Power Management setting GUI not powering off the hard drive(s) when the user ticks the box "Spin down hard disks when possible".
