I am on Arch Linux and I want to disable this activity indicator light on a WD hard drive. I know there is a software on Windows for doing that, but since I am on Linux, how could I do it? This light is annoying when I am in a dark room.
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Activity lights are useful! Try a layer (or two, or three) of matte-finish transparent tape to turn down the brightness a bit.
If that doesn't work, I recommend a bit of black electrical tape.
in even more ways than one might think.

Author wish he was born in 1880 and is not going to give up! (context https://en.wikipedia.org/wiki/Photophone )
PS: thanks for the links, between this PIXHELL, GAIROSCOPE, or SATAn clearly air-gap is just a concept. Fascinating to go through his work basically using everything potential to go through. Great overview in https://arxiv.org/html/2409.04190v1
