How to power down the HDD a la Mac OSX

PGriffin · 11-26-2006, 07:03 PM

Can anybody tell me if it is possible to power down an inactive HDD until.I am using Ubuntu. This is a feature that is part of the Mac OSX power management App.

thanks in advance.

Take a look at the man page for the hdparm command, specifically the '-S' and '-y' options.

Took your suggestion, '-s' seems like the correct parameter to set. With my limited knowledge of unix I am not quite sure how to implement the command, Is there a configuration file or .... that should include this command.

Thanks for your help.

The place you want to put it is in /etc/rc.local. This file will be executed after all the services are started, but before X is started. You'll need to full qualify the path, since the environment is not setup at that point. For example:

/sbin/hdparm -S24 /dev/hda

Also, keep in mind that the parameter is '-S', not '-s'; case is important.

Worked as advertised, with thanks.
