#KEEP DRIVE SPINNING MAC MAC OS X#

The '-a' flag applies the setting to all power configurations (battery, wall power, and UPS).

In this command, VALUE is the number of minutes after which the drives will spin down (with '0' being 'never'). To adjust the disk's sleep time, enter the following command in the Terminal (Note: for 10.4 users, 'disksleep' will be 'spindown'): For specific information on using this command, review its manual page on it by typing 'man pmset' in the Terminal. It also can set the display and system sleep times (though, the sliders work pretty well for those), and what behaviors will cause the computer to sleep and wake (lid opening, wake-on-LAN magic packet via Ethernet, and so on). The command alters the power management settings, giving users fine-tune control of the disk sleep settings. Despite the limits in the control panel, this behavior can be changed manually, by using the 'pmset' command in Terminal. When the option is unchecked, the disks are set to never turn off. When this setting is enabled, the system changes the power management system to turn off the disks after 10 minutes of use.

This can be convenient, but is rather limiting for users who would like to customize when their disks should spin down.

Mac OS X has an option to keep hard drives spinning for quick file access, or to save power and reduce noise by spinning them down when they're not in use.
