11
13 -c --cfgfile=<cfgfile>
14 Load configuration from <cfgfile>. Only available if hdapsd was
15 compiled with libconfig support.
16
17 -d --device=<device>
18 <device> is likely to be hda or sda. Can be given multiple times
19 to protect multiple devices.
20
21 -f --force
22 Force unloading heads, even if kernel thinks different (on pre
23 ATA7 drives). This only works when adding devices by hand (-d).
24
25 -r --force-rotational
26 Autodetect drives as rotational, even if kernel thinks they are
27 not.
28
29 -s --sensitivity=<sensitivity>
30 How sensitive hdapsd should be to movements. Defaults to 15,
31 higher values mean less sensitive.
32
33 -a --adaptive
34 Adaptive threshold (automatic increase when the built-in key‐
35 board/mouse are used).
36
37 -v --verbose
38 Get verbose statistics.
39
40 -b --background
41 Run the process in the background.
42
43 -p --pidfile[=<pidfile>]
44 Create a pid file when running in background. If <pidfile> is
45 not specified, it's set to /var/run/hdapsd.pid.
46
47 -t --dry-run
48 Don't actually park the drive.
49
50 -y --poll-sysfs
51 Force use of sysfs interface to accelerometer.
52
53 -H --hardware-logic
54 Uses the hardware fall detection logic instead of the software
55 one. Options --sensitivity and --adaptive have no effect in this
56 mode.
57
58 -S --software-logic
59 Uses the software fall detection logic even if the hardware one
60 is available.
61
62 -L --no-leds
63 Don't blink the LEDs when a shock is detected.
64
65 -l --syslog
66 Log to syslog instead of stdout/stderr.
67
68 -V --version
69 Display version information and exit.
70
71 -h --help
72 Display help and exit.
73
74
75 You can send SIGUSR1 to deactivate hdapsd for 8 seconds.
