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.
