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.
