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/
-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.
