man(8) ATAidle man(8) 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.
