There was a very popular online photo service that was having cooling issues in their datacenter. They brought in some large floor fans to help cool it down while they waited for repairs. Within 8 hours they were in a full panic as they have lost 40% of the disks in that whitespace. Well one guy started mapping out the lost drive physical location and realized that servers that were within a few feet of the fans had almost complete disk loss. Vibration is Hard Disk killer.

[@GothAlice]

Jarrod, spot on. Had one question come up about a loss of performance after adding a bunch of new disks to the arrays, I asked: what's the harmonic frequency of the spin rates between old drives versus the new? I love when interviewers ask real questions, and begin texting other engineers. And the look, "that… is unexpected" when the responses come back.

That cm of air acts as a nearly impenetrable boundary layer, applying millions of lbs of force, as the Boeing approaches the ground.

I have a large subwoofer, originally from my car, connected to my computer. On one occasion, I played music at nearly 70% of the subwoofer's maximum volume capacity, which resulted in a BSOD. The low frequency sound waves from the subwoofer vibrated the HDD (Hard Disk) so much that it got damaged. Thankfully I've had a backup of the drive. The solution to be able to use the subwoofer at high volumes with the pc, was an SSD.

@@andreasjoannai6441 Of course you can. But, again, the resonant frequency (specifically of NAND chips) falls into the higher end of the sound frequencies and outside the audible range of human hearing, way beyond subwoofer-related frequencies. The reading needles in a HDD are susceptible by lower up to middle frequencies. On the other hand, NAND chips would need a high frequency so strong that probably no current twitter-speakers can produce. Subwoofers are incapable of producing so high frequencies since their range is typically from around 20 Hz to 200 Hz. The upper limit of human hearing is often considered to be around 20,000 Hz (20 kHz), while beyond the range of human hearing, there are ultrasonic frequencies used in various applications such as medical imaging, industrial processes, and animal communication. These frequencies typically start from around 20,000 Hz and extend into the megahertz (MHz) range and these are the ones that can actually influence NAND chips, if strong enough.

[@monado550]

I cannot thank you enough for this video. A few years back I entertained my friends by showing them how my phone would lag and the screen refresh rate bug when shouting at it. I was never able to replicate it on newer models. Thank you for proving to me I am not some sort of genetic freak and that it was, in fact, normal tech behavior. As a matter of fact, screaming at anything will dampen its productivity.

[@nlk294]

When you think about it, it is incredible that this (or other vibrations) doesn't permanentely damage them although the head is just 3nm over the disk.

[@BrendanGregg]

no, I've spoken to hard drive manufacturers about it - load noises or vibrations are a well known problem for rotational disks. If you'd like to read more about it, look up "Effects of Data Center Vibration on Compute System Performance" by Julian Turner, USENIX, 2010.

@@Andika-uy5ir Then allow me to broaden my statement and include that citing sources is strictly limited to academics. Christ, man, it doesn't disprove my point at all. The average American isn't an academic. They're not looking to prove anything. And if they are, they're highly likely going to be guilty of searching only for material that proves their point. Confirmation bias and all that.

I encountered the same issue with servers I installed and maintained at a data center in LA where they had a smoke emergency due to an air conditioner starting a fan belt fire. The halon systems deployed. The frequencies that the halon emitted destroyed 22 of 44 hard disk drives in multiple servers. Upon lab analysis of the hard disk drives, they could see where the disk puck (a.k.a. disk head) impacted the platters. That must have been one loud explosion!

[@MaxLai_0104]

as a data centre, can confirm he was shouting

We have to update our datacenter guidelines. Thanks for the heads up, no shouting in datacenter from now on.

Funny thing. I can feel the hard drive working by putting my hand on the desk (or the computer case). Funny thing 2: If I tried shouting I think I would scare to death my very old neighbor. Yeah, that's motivation enough for me. A classic a-hole and their family too.
