## Path: System/Powermanagement/Powersave/Disk
## Description: These settings determine, how the powersave daemon \
## will adjust your harddisk settings in the different profiles. \
## If you alter something here, you are doing this on your own risk. \
## You should be at least familiar with hdparm (8) and the settings \
## in /proc/sys/vm. Some of these variables contain raw hdparm arguments,\
## any errors in these may cause the proxy scripts to fail.\n \
## DANGER! YOU MAY LOSE DATA IF YOU ENTER WRONG VALUES HERE! \
## You have been warned.

# Shall we start the so-called "laptop mode"? This changes different settings
# in the kernel, most notable after every read from disk, all pending writes
# are written immediately which greatly increases the chance that your disk
# can spin down if there is no further activity. This can harm performance
# quite a bit under some circumstances and thus is default off unless in
# "aggressive powersave" mode. You can set this for all three disk modes
# (performance, powersave, aggressive powersave) here. Default is "yes" for
# aggressive powersave, "no" otherwise.

# shall we remount journaled filesystems with appropriate commit interval?
# this is needed to get the disk to shutdown on ext3 and reiserfs.
# This can be specified for each of the three disk modes (performance,
# powersave, aggressive powersave). The default of these settings is "If
# HD_LAPTOP_MODE is set to yes for this mode, do remount".

# support automatic acoustic management (AAM). Change only if you

# Valid values are 128 (quiet) to 254 (fast), 0 disables this setting.

# "hdparm -B" arguments for STANDBY_MODE settings
# "performance", "powersave" and "aggressive_powersave".
# Change only if you know what you are doing! Also see the
# "hdparm" manpage to learn more about those settings.
# The support of the drive for APM is checked before issuing those
# command, so these settings may have no effect on your hardware.
# For many laptop harddisks, the APM settings are defined as follows:
# 255: APM off
# 192-254: "active idle" - not too much savings
# 128-191: "low power idle" - heads may be parked
# <127: "standby" - disk may spin down even without a spindown setting
# 0: special value, disables the "hdparm -B" setting.
# These values are dependent on your harddrive model!
# Note that spinning down the disk leads to spurious lockups on some
# machines (e.g. Dell D600), so be careful.
#
# Performance default is 254 instead of 255 (off) since this will let
# a lot of drives run cooler without significant impact on performance.

# doing! These are the last parameters on the hdparm command line, so
# they may override HDPARM_STBY_* and HDPARM_ACOUSTIC_* settings.
