OPTIONS

12       -d --device=<device>
13              <device> is likely to be hda or sda. Can be given multiple times
14              to protect multiple devices.
15
16       -f --force
17              Force unloading heads, even if kernel thinks different  (on  pre
18              ATA7 drives).  This only works when adding devices by hand (-d).
19
20       -s --sensitivity=<sensitivity>
21              How  sensitive  hdapsd  should be to movements.  Defaults to 15,
22              higher values mean less sensitive.
23
24       -a --adaptive
25              Adaptive threshold (automatic increase when  the  built-in  key‐
26              board/mouse are used).

31       -b --background
32              Run the process in the background.
33
34       -p --pidfile[=<pidfile>]
35              Create  a  pid file when running in background.  If <pidfile> is
36              not specified, it's set to /var/run/hdapsd.pid.
37
38       -t --dry-run
39              Don't actually park the drive.
40
41       -y --poll-sysfs
42              Force use of sysfs interface to accelerometer.
43
44       -l --syslog
45              Log to syslog instead of stdout/stderr.
46
47       -V --version
