How Do Hard Drives Work?

A short simple explanation of how spinning disks store and interpret binary data.

I think it's mind blowing that we as humans were able to figure all this shit out and put it together, AND get it to work. It's impressive.

I watched couple of videos about this subject, and you explained the subject far better then some professor here. Thank you.

You do a wonderful job of simplifying these concepts! I now have a solid understanding of things that were completely foreign to me just a few hours ago -- thank you!

I had seen the binary vid some time ago
But that time I hadn't checked out your other other videos.
Now that I have seen a number of them I just love your vids
The explanation gets stored in my brain so quickly
THANK YOU SO MUCH.
PLS DONT EVER STOP TEACHING ON YOUTUBE EVER
AND YOU MUST GIVE LESSONS TO SOME PEOPLE SO THAT THEY CAN ALSO TEACH LIKE THIS IN THE FUTER.

I've come around this after watching the video in which you explained the binary system and must say, as many approve too, that you do a great job at explaining. Im going to proceed watching the other explanatory videos, highly wanting to learn and understand more abour this topic in a clear way.

Going to school for IT and just found your channel today. Your videos are so easy to digest and have helped me understanding some complicated concepts from class. Thanks!

Being rather 'ancient' in human terms, I have been trying understand the workings of computers for over half a century now - without much success! Your lucid explanation, however, gave me an 'Aha' moment and, having subscribed, I look forward to learning much more from your beautifully presented tutorials. Thank you very much.🙏

i find it very fascinating how we’ve made such precise physical instruments that can store and read data constantly without damaging the disk or corrupting the data. still not the most reliable way of storing data at least in the very long term however i have read about glass storage devices called “5d optical data storage” that due to glass being an inert material and if stored properly can theoretically store data for billions of years and a single disk can store up to 360TB however data written is permanent

I am an eighty year old learner - this vid explanation helps bridge the age gap - very helpful - Thanks !

[dipunkumarpalia]

Never did I get more clear understanding on this topic, all thanks to you

[yeturiyashwanth]

Bro ur the best teacher. I am doing bachelors degree in computer science these videos u make help me to gain knowledge than my college provides me
Thank u a lot

[sophylong]

I'm amazed by the simple way you get to explain all this. Love it!

[ImmiTheKhan]

Finally, I found a person who would like to know what is happening under the hood and learn up. you are great master, please make more videos and you will sooner have a million subscribers. there is a dearth of teachers like you.

You know, you're one of the genius minded in the world .
You are making a difference.
Thank you very very much.
I hope that your dreams came true .

In a game called "The Powder Toy" I made a storage drive that can store 128 bytes of data.

Thanks a ton. Not many people can explain this in a easy way. Appreciate the hard work put in making these vedios.

One of the most informative videos I've ever seen.

I have two questions, potentially dumb ones but I'm still going to ask:

1. When you're taking about " positive or negative charge" on the magnet, we're talking about polarity here, right? Is this the same thing as calling the poles "south" or "north"?

2. How do the regions make sure their polarity or the electrical charge they've received does not cross over to their adjacent regions? I mean do they have some kind of potential "wall" to prevent accidental spillage of charge?

I'm 16 years old and curious about these freaking things....I haven't found any video regarding this topics...But finally found a legend channel H3Vtux...Bro you're really life for this content...I have just subscribed your channel....Still keep on making these contents brother....

I really understood these concepts which I didn't in many lectures in college
Thanks mate👍👍
