       hdapsd - park the drive in case of an emergency


       hdapsd           [-f|-r|-c           <cfgfile>|-d           <device>|-s


       -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

       -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/

       -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

       -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.
