hdapsd (8)

NAME

SYNOPSIS

OPTIONS

-c --cfgfile=<cfgfile>

Load configuration from <cfgfile>. Only available if hdapsd was compiled with libconfig support.

-d --device=<device>

<device> is likely to be hda or sda. Can be given multiple times to protect multiple devices.

-f --force

Force unloading heads, even if kernel thinks different (on pre ATA7 drives). This only works when adding devices by hand (-d).

-r --force-rotational

Autodetect drives as rotational, even if kernel thinks they are not.

-s --sensitivity=<sensitivity>

How sensitive hdapsd should be to movements. Defaults to 15, higher values mean less sensitive.

-a --adaptive

Adaptive threshold (automatic increase when the built-in keyboard/mouse are used).

-v --verbose

Get verbose statistics.

-b --background

Run the process in the background.

-p --pidfile[=<pidfile>]

Create a pid file when running in background. If <pidfile> is not specified, it's set to /var/run/hdapsd.pid.

-t --dry-run

Don't actually park the drive.

-y --poll-sysfs

Force use of sysfs interface to accelerometer.

-H --hardware-logic

Uses the hardware fall detection logic instead of the software one. Options --sensitivity and --adaptive have no effect in this mode.

-S --software-logic

Uses the software fall detection logic even if the hardware one is available.

-L --no-leds

Don't blink the LEDs when a shock is detected.

-l --syslog

Log to syslog instead of stdout/stderr.

-V --version

Display version information and exit.

-h --help

Display help and exit.

You can send SIGUSR1 to deactivate hdapsd for 8 seconds.
