+
+ Writing an integer value to this file will take the heads of the

+ for the specified number of milliseconds.
+
+ - If the device does not support the unload heads feature,

+ - The maximal value accepted for a timeout is 30000
+ milliseconds.
+ - A previously set timeout can be cancelled and disk can resume
+ normal operation immediately by specifying a timeout of 0.
+ - Some hard drives only comply with an earlier version of the
+ ATA standard, but support the unload feature nonetheless.
+ There is no safe way Linux can detect these devices, so this
+ is not enabled by default. If it is known that your device

+Contact: linux-ide@vger.kernel.org
+Description:
+ (RW) This parameter allows the user to read and set the link
+ (interface) power management.
+
+ There are four possible options:
+
+ min_power: Tell the controller to try to make the link use the
+ least possible power when possible. This may sacrifice some
+ performance due to increased latency when coming out of lower
+ power states.
+
+ max_performance: Generally, this means no power management.
+ Tell the controller to have performance be a priority over power
+ management.
+
+ medium_power: Tell the controller to enter a lower power state
+ when possible, but do not enter the lowest power state, thus
+ improving latency over min_power setting.
+
+ med_power_with_dipm: Identical to the existing medium_power
+ setting except that it enables dipm (device initiated power
+ management) on top, which makes it match the Windows IRST (Intel
+ Rapid Storage Technology) driver settings. This setting is also
+ close to min_power, except that:
+ a) It does not use host-initiated slumber mode, but it does
+ allow device-initiated slumber
+ b) It does not enable low power device sleep mode (DevSlp).
