okay bestie, this is the hdapsd page from section 8 of the manual — emergency drive-parking main character energy 🚨💖

🌸 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 💅

okay so here's the whole flag lineup, bestie — every single one, no skips 👑

  • -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 🆘
psst — you can send SIGUSR1 to deactivate hdapsd for 8 seconds ⏳
