I have wondered this for a long time: Floppy/Hard drive activity lights used to be red. Or sometimes amber. Then eventually they all became green. Does anybody know why this is? Someone once told me people were returning products or calling tech support because they thought a red activity light meant the drive was broken. Why did they change?

Red is a very angry colour, it's the same as the move away from the teacher using a red pen to mark a pupil's text book.

Studies have shown that this causes PTSD.

Now they'll return it because it's not RGB.

Funny story about red pen: I was fired from my first job for my blog. ;The write ups they could do there were on a computer; one page, single spaced. My boss wrote an additional three pages in red pen.

LED were expensive, and red was the cheapest available when they first were available...
I remember the old single side 5.25" Shugart assemblies I had, yes round panel mount red LEDs. These drives were for home machines and they did need to keep the price down.

I recall the 8" drives of the same vintage I had were amber and lensed. The 8" drives were double sided 1.2M and were pretty much the bees knees (though obsolete by then too) so I suspect someone took the liberty of using more expensive LEDs.

Granted I do recall having a 3.5" HD drive with a red LED...

Honesty I would appreciate dual color LEDs to indicate the difference between reading and writing, but the main purpose is to ensure people don't corrupt data regardless of corrupted read into memory or corrupted write to disk. Lit means active, but then open but inactive files are also dangerous to remove disks.
Then the realization that color doesn't matter especially after LEDs significantly dropped in prices. Now we have blue hard drive activity lights which underwent a similar color shift (the Seagate ST412 also had a rectangular red LED, though it was quick enough the ST251s I had were already green...).

It's because red LED light stimulates the skin on a cellular level, promoting collagen production and cell renewal; both necessary to tighten, firm and revive tired skin. With consistent use over a period of several weeks, fine lines and wrinkles will gradually soften, leaving behind a smoother, more refreshed complexion.

I just changed a 3.5" with a red :LED. I still have the family's first computer, an NEC PowerMate1 286. Last year I saw another one sitting out with the trash so I scooped it up. Reseated the video card and replaced the 5.25" fd0 with a NOS 3.5" unit and I had a working machine. Not sure what was on it before, closest HDD type I could find was a 40ish MB for a 70ish MB drive, so I had to low level format. The (original?) 3.5" fd1 just died and the new used unit I put in has a green light. Made me remember when the my 286 had red floppy drive lights. I've always wondered about that.

The factory 5.25" drive from my 286 failed in 1998 or so. Changing that drive was the first computer repair I ever did.

Have you noticed any reduction in the quality of your skin tone or elasticity.

Why...YES! This morning I awoke and my entire body looked like an old catcher's mitt! Look away, I'm hideous! :P

My biggest complaint about drive activity lights is that they are going extinct altogether, at a time when they're more important than ever before! You can put an ear close to a spinning drive and hear whether something is going on, but if you can hear your SSD working there's probably something seriously wrong...

Agree 100% ... Only saving grace is Linux that at a low level will expose activity to user space, which helps...

Just that proprietary kernels that take an arm and leg to hack and re-sign due to secure boot (looking at embedded, how is this not a gpl violation?)

Just hit ctrl+alt-del and bring up the Task Manager, then switch to performance monitor mode. On Linux, you can install Conky! :roll:

Sounds like ol' JB's speaking from experience. Need to talk to someone about it? ;)

I used to work in IT support. My therapist tells me that feelings of rage are quite normal given this.

me too. it was a call center. since then i had rage attacks when somebody (mother, friends, family) called me on my cellular. also i used to tend to quit the call within a minute. fortunately now i am fine but it took me almost 20 years. some jobs are not meant for humans.

I've never worked in a call center, so being timed wasn't an issue, but decades where incoming calls mean problems kind of establishes a physiological response. If I could have one non-standard luxury, it would likely be to live the rest of my life without a phone. Other than bad UI and being a safety hazard, I also think there is a relation to my dislike for touchscreens in automobiles.
