NAME
       ataidle - a utility to spin down	ATA drives

SYNOPSIS
       ataidle	[-h]  [-i] [-s]	[-o] [-I standby_mins ]	[-S standby_mins ] [-A
       aam_level ] [-P apm_level ] device

DESCRIPTION
       ATAidle sets various power management features on hard drives,  includ-
       ing timeouts to switch to idle and standby power	saving modes, and set-
       ting  the  APM  (power) and AAM (acoustic) levels.  If only a device is
       specified, without options, information about the selected device  will
       be shown.

OPTIONS
       -h     Show usage information

       -i     Puts the drive into Idle mode

       -s     Puts the drive into Standby mode

       -o     Puts the drive into Sleep	mode

       -I     Puts  the	 drive into Idle mode and configures the standby timer
	      to put the drive into Standby mode after standby_mins minutes of
	      inactivity.

       -S     Puts the drive into Standby  mode	 and  configures  the  standby
	      timer to put the drive into Standby mode after standby_mins min-
	      utes of inactivity.

       -A     Set  the	acoustic  level	of the hard drive.  This allows	you to
	      reduce the acoustic output of the	drive at the expense  of  per-
	      formance.

       -P     Set  the Advanced	Power Management level of the drive.  This al-
	      lows you to reduce the power consumption of the drive at the ex-
	      pense of performance.  A low apm_level will cause	the  drive  to
	      go into Standby mode to save power.

NOTES
       Notes on	Auto Acoustic Management (AAM) and APM support

       AAM  and	APM settings are vendor-specific and not all intermediate val-
       ues may be valid.  If you set an	invalid	APM value you will be notified
       that it failed -	when setting an	AAM value you should check the	output
       of 'ataidle <device>' to	see if it has been updated.  If	it hasn't, the
       value isn't supported and you should try	a higher or lower setting.

	      Meaning of AAM values:

       0      Acoustic management disabled.

       1      Minimum noise.

       2-126  Intermediate noise levels.

       127    Maximum performance, maximum noise.

	      Meaning of APM values:

       0      APM disabled

       1      Minimum power usage with Standby (spindown).

       2-127  Intermediate power usage with Standby.

       128    Minimum power usage without Standby (no spindown).

       129-253
	      Intermediate power usage without Standby.

       254    Maximum performance, maximum power usage.
