is there a way to stop the hard drive when its not in use?

Like an energy saver feature?

I have a Mackbook black series.

Thanks in advance.

Some machines do not natively go into hibernation with Ubuntu installed, my Sony Vaio didnt at first but i found this online and then i was able to put my machine into hibernation when i closed the lid the code is : sudo gedit /var/lib/polkit-1/localauthority/50-local.d/hibernate.pkla

and then paste this code into the file that opens in terminal:

[Re-enable Hibernate]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=yes

If you go to system settings > brightness and lock > select dim screen to save power
