NAME

       hdapsd - park the drive in case of an emergency

SYNOPSIS

       hdapsd [-f|-d <device>|-s <sensitivity>|-a|-v|-b|-p|-t|-y|-l|-V|-h]

OPTIONS

       -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).

       -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.

       -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.
