This Janet Jackson BASSLINE breaks laptops

This Janet Jackson BASSLINE breaks laptops :-DD
(Warning: Do not listen to on an old laptop with a 5400rpm HD if the manufacturer hasn't applied the audio filter in their sound card driver...)
AVGresponding:
I think you mean 5400rpm (90Hz)? Presumably this also means 7200rpm drives would potentially be vulnerable to 120Hz resonance...
Halcyon:
I call bullshit.
EDIT: Sorry, I should clarify, yes, really loud noises and harsh vibrations can damage hard disks. That's nothing new. As for laptop speakers (or even typical desktop speakers) causing problems, I highly doubt it. Whilst spinning rust hard disk drives are precision instruments, they are pretty resilient, especially the 2.5" laptop drives. Not to mention laptop speakers simply wouldn't have anywhere near enough output capability to be able to damage anything. They would tear themselves apart long before they damage a hard disk.
Also, why single out laptops? There are several all-in-one desktop machines and car infotainment systems that used 2.5" drives with much bigger speaker drivers/woofers, yet, no signs of any issues there.
Finally, as a gay guy who listened/listens to a lot of Janet Jackson at volume, I've never killed a hard drive.
BrianHG:
From what I saw, I bet it was one particular drive type. I do not believe that the drive was mechanically damaged, definitely not enough vibration for that, the only thing I could think of is that there is a tone or note, most likely not even a bass one, but a high frequency one which resonated with the linear head servo tracking armature positioning feedback and class D drive tracking amplifier's circuitry.
I agree the volume isn't enough for a classical mechanical problem, however, a perfect fluke circumstance of drive design and how the head tracking linear servo which uses a class D positioning amp with feedback can be manipulated to oscillate like mad with the perfect tone in the few khz range. This might even trigger the emergency 'anit-shock' shutdown feature available on some drives. Or, the linear servo tracking amp's class D servo driver in this circumstance will momentarily draw too much current, or even short out. The low 80hz tone affecting the drive is BS unless you pump hundreds of watts of acoustic power right into the drive while writing data.

Presumably because of the close mechanical coupling involved in laptops and their speaker systems. I have doubts also, but it's theoretically feasible if your laptop and HDD is badly enough designed.
Given the rotational speed of the platter is a known factor, and given the incredibly small distances between bits/tracks on the platter, I expect resonances around that frequency and its harmonics are designed out. Still, designers and engineers are human too, and mistakes can be made :-//
