Below is the man page for pmset, I can't find a way to adjust
only one drive, but on a laptop, you might want replace the -a
flag in my tip to -c which should allow the drives to spin down
when you are on battery power.

NAME
pmset - modify power management settings

SYNOPSIS
pmset [-a | -b | -c] [dim minutes] [spindown minutes]
[sleep minutes]
[womp 1/0] [ring 1/0] [autorestart 1/0] [dps 1/0]
[reduce 1/0]
[boot] [powerbutton 1/0]
pmset -g [disk | live | cap]

DESCRIPTION
pmset changes and reads power management settings such
as idle sleep tim-
ing, wake on administrative access, automatic restart on
power loss, etc.

SETTING
The -a, -b, -c flags determine whether the settings apply to
battery
(-b), charger (wall power) (-c), or all (-a).

Use a minutes argument of 0 to set the idle time to never.

pmset must be run as root.

The boot argument tells power management that system
bootup is complete.
Loginwindow handles this on a normal Mac OS X system.

GETTING
The -g flag outputs the settings currently in use (same as -g
live ). -g
disk will tell you the settings on disk. -g cap will tell you
which
