HDAPSD

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.
