💖 NAME 💖

okay so hdparm.conf(5) is the Debian configuration file for hdparm, and it's giving main character energy 🎀✨

🌸 DESCRIPTION 🌸

This is the default config for hdparm on Debian 💅 It's a pretty simple script, so bestie, please follow the guidelines :) Any line that starts with a comment is ignored, so add as many as your heart desires 🫶

Since hdparm doesn't use an init script anymore, this config is mainly used by udev 🔧 Still, you can re-apply the settings from the config file by running either

/usr/lib/pm-utils/power.d/95hdparm-apm resume

or

DEVNAME=/dev/<disk> /usr/lib/udev/hdparm

Quick heads up: an in-line comment is not supported 🙅‍♀️ If a line is only whitespace (tabs, spaces, carriage returns), it gets ignored, so you can space out your control fields however you like 🦋 But ANYTHING ELSE IS PARSED!! 😭

So any line with stray characters, or any line using a non-# comment character, will get interpreted by the initscript. The side effects are probably minor, but they could be seriously bad for your hard drives 💀 So please, please follow the guidelines. Patches to improve flexibility are welcome 💜

Heads up: if the init script causes boot problems, you can pass nohdparm on the kernel command line, and the script won't run at all 🚨

Setting an option outside of one of the stanzas turns it on for all drives 🌈

If an option is listed twice, the second one replaces the first 🔁

/sbin/hdparm doesn't run unless a block of this form exists:

DEV {

option

option

}

That block is what makes /sbin/hdparm OPTIONS DEV run ✨ Here, OPTIONS is all the options you defined outside of any block, plus all the options defined inside the block, mashed together 🧚

🎀 OPTIONS 🎀

See man 8 hdparm 🍓
