They're not completely obsolete, they do have a huge role where large amounts of data are needed to be stored, but not frequently accessed, so like on a lot of servers
Back in 2001 I was a mechanical engineer at Iomega in Utah. We explored using this exact Hitachi drive as a platform for removable drives (in place of the Zip drive). The idea was to have Hitachi supply the guts (motor and platter) and we would incorporate that into an enclosure that mated up to the host which contained the arm, heads, magnets, ramp and so on. The challenge was the mechanical interface - how to prevent any speck of dust from entering the enclosure while the drive was mounting. In the process we took apart a lot of these drives. We also looked at adding a micro laser burner on the head and built some prototypes but they were way too finicky to manufacture. (We called that the OZ project: Optical Zip) One of the things that are not apparent is the "fly" hight of the head which is less than a micron. The bottom of the head has a zirconium layer (very hard) and the media has a DLC (diamond-like coating) in case the head skates a bit. To me the magnetic drive is a marvel.
You see how smart and fast technology is becoming and soon gonna defeat all human capabilities like thinking that pin was moving so fast it gave me that vibe
Basically NEVER DO THIS! And if you do, only with a drive that you don't care about the data. I wonder if once this drive inevitably breaks down, if some data could still be salvaged, but I wouldn't expect much.
yes, however data recovery stores will often have a clean room or box that the drive is less likely to get dirty in. The only reason to open a drive is in a worst case scenario where small physical repairs are necessary in order to attempt to get the drive to work again long enough to get any important data off. If you get a drive repaired, do not use it as it most likely will fail within a few days or weeks.
This was so interesting! I have only ever read books and seen picture diagrams of how platter hdds work! I never knew you could safely open up an hdd and plug it in (of course it would be a disposable hdd just for learning purposes). So interesting!! My geek side has been activated 😄
Spinning can only happen with DC current because it moves in one direction only. But the city power you used is AC which oscillates at a frequency of around 50/60 Hz which causes a switching in the magnetic field and basically results in a push-pull effect and results in a net zero force and does'nt cause the spinning of the spinner.
The greatest thing about SSDs is the fact that you dont risk destroying it by opening it And also better read and write times And also more compact And also more energy efficient And also silent

I opened a HDD one time because I thought it would be cool to replace the metal cover with a custom clear perspex one. It had RGB too of course and I was really happy with how cool it looked. That was until I wanted to see it in motion and plugged it back in. Despite my best efforts to keep it debris free there was some crud on a platter and the arm instantly ruined it. I took it out and threw it in the bin straight away. Moral of the story is don't ever open a HDD. It really did look cool though.
people, don't open your drives if you want them to run afterwards
@USSF - United States Space Force you will get dust in it and it will break at some soon point

SOLID STATE HARD DRIVE... i hate my life
A SSHD is a complete different product.
Shut up, nerd
@@horaryzappy I was calling the other guy a nerd
@@horaryzappy I'm just playing
@@horaryzappy Why so angry my dude?
Why can I listen to this guy for hours and not get bored
These are the stuff they should've been teaching us in school, man!!
you took me back when I went to Duke U for a network engineering program and I had the professor do this very same thing :) that was fun
This is giving me vibe of world end by technology
How?
You see how smart and fast technology is becoming and soon gonna defeat all human capabilities like thinking that pin was moving so fast it gave me that vibe
@@swapnilpatil7326 yea but hard drive were here forever
@@swapnilpatil7326 the pin is sure moving so fast but the fastness in computer is shit
It's the computer's processing power. Not the hard drive.
20 years of working with computers and I never thought about this at all. That is so fucking cool. Thank you for making this video.
Wouldn't exposure to the elements corrupt the drive? Such as the introduction of dust particles and whatnot.
Yeah and then this video won't be possible to make
its much like opening up a corpse, cant get it back to the way it was, but it is informative at least
Basically NEVER DO THIS! And if you do, only with a drive that you don't care about the data.
I wonder if once this drive inevitably breaks down, if some data could still be salvaged, but I wouldn't expect much.
yes, it will break it down in the long run. I'm guessing the creator didn't care about this drive.
yes, however data recovery stores will often have a clean room or box that the drive is less likely to get dirty in. The only reason to open a drive is in a worst case scenario where small physical repairs are necessary in order to attempt to get the drive to work again long enough to get any important data off. If you get a drive repaired, do not use it as it most likely will fail within a few days or weeks.
I mean you could be faster than the speed of light and yet there's an ssd still faster than you.
Is this an Asian joke

I like the way the storage modules are placed inside of your ssd... 3:10

This was so interesting! I have only ever read books and seen picture diagrams of how platter hdds work! I never knew you could safely open up an hdd and plug it in (of course it would be a disposable hdd just for learning purposes). So interesting!! My geek side has been activated 😄
only some HDDs work though, some require the arm to be affixed to the lid as well.
I'm a straight guy, but i felt his voice in my spine. I don't listen to any, but this is the best ASMR i've heard. I'm glad this was recommended
As a kid, I had a blast collecting broken Hard Drives and dismantling them to take the disks and the magnets. I still have them today lmao
Yeah the magnets are so strong
i’ve took one apart and spinning the motor with the platers is so fun
me: tries opening folder on my computer
hard drive: intense movement intensifies
It's almost like a piece of art the way it's designed.
7:22 damn, that's one fragmented drive.
lmao
Wow I now have alot more respect fore my hard drive, even tho it's slow af I know it's trying it's best.
As an experienced computer engineer, I can confirm that that is indeed a hard drive.
ok
Spinning can only happen with DC current because it moves in one direction only. But the city power you used is AC which oscillates at a frequency of around 50/60 Hz which causes a switching in the magnetic field and basically results in a push-pull effect and results in a net zero force and does'nt cause the spinning of the spinner.
That's how an AC motor works. But a computer has a power supply to convert 110 AC to 12v and 5v DC power. Hard drives have DC stepper motors in them.
@@vsvenson Oh
@@vsvenson im pretty sure its a brushless motor. Steppers are slow af

thats just called surgery
that's looks pretty alien and abstract tbh
Amazing how fast and acurate it operates. And still last for years.
Wow thats crazy how precise that has to be ..no wonder hard drives fail so often....technology is crazy nowadays
Great video. Even after having been using computers for decades I always wanted to do this but never did.
When u were showing it at 0:24 the data feed is on the left... the smaller one.
Nice video though. That's cool
I pointed that out to myself. Glad to know I’m not the only one who knew the right order, hehe.
Thanks for your comment, I got really confused between what I already knew and this one.
This is actually a pretty down-to-earth and informative video
I'm amazed that you can read data off that thing while cracked open! Hard drives truly are black magic
The greatest thing about SSDs is the fact that you dont risk destroying it by opening it
And also better read and write times
And also more compact
And also more energy efficient
And also silent
And also pricey
And also have limited writes
And also can loose data if left unplugged for too long
And also data recovery is very hard

How about, stfu with this meme 🤷♂️
stfu pls

What if we all decided to stfu for no apparent reason
When I was little I used to love tearing apart dead hard drives. Taking a screwdriver and disassembling it was so much fun for my adhd brain
this comment is a time capsule to be recommended to the next generation of humanity today jun 12 of 2020 and im currently on enhanced community quarantine or ECQ as some people like to call it bye
Holy shit the arm looks so insane moving at such speeds
haha the arm go brrrr
When we dive deep into old techs its always amaze you.. Look the speed of the r/w head. With the precision
I opened a HDD one time because I thought it would be cool to replace the metal cover with a custom clear perspex one. It had RGB too of course and I was really happy with how cool it looked. That was until I wanted to see it in motion and plugged it back in. Despite my best efforts to keep it debris free there was some crud on a platter and the arm instantly ruined it. I took it out and threw it in the bin straight away. Moral of the story is don't ever open a HDD. It really did look cool though.
@Informatico We live and we learn haha
@Informatico it's not vacuum, just packed in a very clean environment
I wish someone made 1 hour ASMR of this running..
That was actually really cool to see it run! Very well made video!
I really wanted to see what would happen if he scratched the platter
it glitches and the laptop wants to kill you
Most likely all the data might be corrupt and explode
@@NoOneAlive_ not sure about the explosion but the data might be corrupted , since the platter is made of a bunch of little magnets
Data corruption. It would be nearly impossible to retrieve the data after that.
@@maskedredstonerproz well i mean if one of the platters where to be weakened by a chip or something at the speed its spinning it could explode
