hdapsd - park the drive in case of an emergency
hdapsd [-f|-r|-c <cfgfile>|-d <device>|-s <sensitivity>|-a|-v|-b|-p|-t|-y|-H|-S|-L|-l|-V|-h]
-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.
