NAME

       hdapsd - park the drive in case of an emergency

SYNOPSIS

       hdapsd                  [-f|-r|-c                 <cfgfile>|-d                 <device>|-s
       <sensitivity>|-a|-v|-b|-p|-t|-y|-H|-S|-L|-l|-V|-h]

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.
