Can Magnets Scramble Computers? | I Didn't Know That 

That's why I came here

Lmaoo, I was looking that scene up to show my brother and this video also popped up lol

Real life isn't as impressive ig

Bahahaha

massive*

+Killer2600 Agreed this guy is an idiot

+Killer2600 All mechanical drives have neodymium magnets in them to allow the voice coil that actuates the heads to work. You'd need a magnet much stronger than that to cause damage to the platters considering those magnets are right next to them. The easier method to wipe a drive besides using dangerously strong magnets would be to use a degaussing coil for several minutes.

GGigabiteM That has nothing to do with the scientific method of testing. In the video, we're trying to mess up a hard drive not wipe it beyond the point of NSA recovery so we only need to scramble a file or two and test and see if indeed we have done so. This entire video, up till the near end, there was no data integrity testing being done. Watching the screen as you pass a magnet over the hard drive tells you nothing about the data on the hard drive. A computer can run and display the desktop even if you pulled out the hard drive while the computer was on.

+Killer2600 Hahaha how about you try that with your hd that has your operating system installed on it

***** Thank you kind sure.

I completely agree, I was confused as to why he only rebooted it after the most powerful magnet.

@@valaxiar Probably because they either turned it off before the more powerful one or the more powerful one was simply strong enough to crash the system into being powered off

totally, poor experimentation technique. i would also like to have seen whether he could reformat that drive and still use it

Magnets!

Wire....

was waiting for this comment

yeah science!

I actually put a small magnet onto my laptop before cause I was curious, not a very smart thing to do as my laptop is a gaming laptop so it's worth some amount of money. Not exactly sure what the effects of the magnet was on my laptop but my laptop did turnoff by itself when I put it in around the same area he did. However there wasn't any damage to the laptop itself.

Windows needs the pagefile to work and that located on the harddrive, it would crash if it lost access to it.

The complete lack of knowledge of computers and physics here and in the comments section scares me.

Tom Cho Windows only uses the "paging file" as additional memory while it is "working". if you are just sitting on the Windows desktop not running any programs you cold completely remove the HDD if you had plenty of memory installed and you would not notice anything on the screen until you actually tried to do something. The problem would arise when you tried to reinstall it, it would crash then.

This is the most perceptive comment, good point!

Magnets, BITCH!

...fml I thought it was dropping the laptop that killed its hard drive

ahhaahhahah awesome

anjopag31 nope

Breaking bad yo

ha ha only reason im here

+JacobTheButtonMasher it would probably be dead on arrival

+Nash B I`d laugh at that diss, but it kinda hits a little too close to home. *glances at 1 year old busted external hardrive*

scratch that, it'd probably dead straight after its built.

Don't be silly, he wasn't checking to see if it was breathing. He was trying to see if the heart was still beating.

Or you could hand it over to TechRax

+♡iDon'tGiveAFuck♡ Yeah just have a refrigerator-sized electromagnet at home.

no I use it to download information from a computer to a USB then clear the hard drive with a neudinium magnet

Ozarkz ik

If you notice that clip was after he plug it in. Just seem the video editor put in it before.

Nope, a harddrive would've EASILY survived that Fall ;)

Tbf that laptop looks like a nokia so its probably not why it broke

Harddrive would've been intact.

***** Well that is true but you got to remember theirs sensitive hard drive controllers on the board. So if you wipe the controller boards micro controller then the hard drive would be about as useful as a brick.

***** yep

Yeah thats exatly why i am looking at this video right now. Wante to know if it is true

LOGANxFLUFFY Xcat It reminds me of some cartoon kid's movie I can't think of the title though.. the red magnet thing has this evil looking face on it and the.. yeah the brave little toaster, that's it. lol.. just remebered.

+LOGANxFLUFFY Xcat Oh good I'm glad it worked otherwise I was about to say Breaking Bad lied to me. The cops found Walt and Jesse in the lab on Gus' computer and they were arrested and Hank went into a depression cause Heisenberg was at dinner with him.

I was just about to say that lmao

rip cheese pizza

Windows would probably bluescreen if the hard drive failed.

I agree but id imagine they restarted it between the huge magnet and the small ones, maybe some data was corrupted but not enough to prevent booting into the OS

Full episode was longer and they were checking every time.

+Ryan C it was a joke breh relax.

Modern computers usually use SSD's, which will not be affected by magnets.

Wut, almost every single computer I know, has SSD. Even my $300 laptop has SSD, also my desktop has SSD and my external HDD has two 500gb SSD's in it. I would say it's not that expensive anymore, almost everyone has it.

I'm sure I have SSD's. Because I've bought every single laptop and desktop, built/upgraded them myself. The thing is that nobody is using HDD's nowadays. People are getting smarter and smarter, even some random grandma could replace their old HDD with SSD. Everyone I know, has been using SSD's for years. Not to mention that most of our tech companies give you options when you are buying a laptop computer. You can choose between SSD/HDD and how much RAM you need. When I was finishing my school, then I was working at some local store and let me tell you that - nobody wants HDD's anymore. I've been thinking about getting one SSD to my Raspberry Pi 3 as well, since there is no real point of attaching a noisy HDD anymore.

too bad a decent 1tb ssd costs 5 times more than a 1tb hdd

exactly, to test if the hard drive was damaged by the magnet he should of tried opening a fairly large file.

windows 7 is stored in the hdd your ram is random acess memory and everything is deleted when you shut down the computer

windows 7 is 'installed' to the hdd. when the computer does its "POST", its checking to make sure all hardware is functioning properly. if the "POST" completes, it then looks at the HDD for its 'master boot record' (using 'master boot record' as an example, since most 'windows' installations are done on an NTFS partitioned hard drive usually under 1TB in size). The master boot record tells the hardware where the OS is installed, and beings to LOAD IT INTO RAM. this is why when you go into Task Manager upon the system freshly booting, and see that roughly 20% of your RAM is currently in use. This is also the reason why windows has 'minimum system requirements' for installation of the OS. It needs a certain amount of RAM so it can be loaded into it. A hard drive is simply a 'storage location' for your data. While RAM, although still considered a type of 'storage', is used by running code/applications which are needed to operate/perform any given task. Meaning, your OS has to be loaded into RAM in order to function. When you are moving your mouse around, its location is stored in RAM. when you're watching a video with VLC player or Windows Media Player, the file is either fully, or partially loaded into RAM. Anything that is 'active' or 'open' on your computer, is stored in RAM for quick access and ability to be changed. This is why you should never really just 'press and hold' the powerbutton on a computer to turn it off.. because you're not giving the computer a chance to save what is in RAM onto a HDD for permanent storage.

the ram is only things that are running so not all of the os is in the ram

***** I'm not 100% sure on how SSDs exactly work. but i have a feeling they wouldn't be affected either. From what I've understood, they physically change states, not just electrically. That's why they wear out after so many read/write cycles. Every time you 'write' to the drive, you're electrically changing a cell, and each time the cell is changed, its physically damaged an extremely small amount. which is how it 'stores' the data. but again, i'm not 100% sure, never really took the time to read up with SSDs

That fucking profile picture fits that comment

Why use an acid and a hammer, when a good electric spark can do the job?

True, they are also cheaper than the last magnet used.

uhh no it wasn't

yes it was running xp...

Capperith it was running 98. thats a dell latitude, i fucking own one running 98

I got so excited about that so i came to comment about it and then i found your comment. Blast you.

Ha Ha. Funny = )

There is no steam icon. Wtf you talkin bout robertas.

+CookiesNMilkFilms doesn't have the same effect on television as a giant magnet

+the stalking biscuit i dropped four neodynium magnets on top of the spot where the harddrive is on my school computer once, the screen went crazy and it rekt my harddrive, pro tip, dont do it.

ababaaba i believe that, but stupid people get more impressed by BIG stuff, like, this magnet is giant, so it must be very powerful!

+ababaaba lol I did the same to my dads computer

"you breathing, HDD?" Ha, I thought the same!

he was checking if it was spinning.

since HDDs function consist of various moving parts, they can show several audible simptoms including whining noises, clicking noises, erratic or no spin at all of which can help determine the cause and level of the damage.

This comment is fake. I looked at it and my computer immediately wiped it's own hard-drive. (insert both comments being semi-trolls here. c;)

Hello John :D

you do realize that if you drop something on your hard drive its internal mechanics may be damaged rendering the drive unusable? in no way would a 5W speaker magnet be able to erase anything off a hard drive.. you need a very powerful magnet to achieve degaussing i very much doubt that even the electro magnet in this video is enough to permanently delete all data on the hard drive they never even checked for data retention, they just checked if the hard drive worked which of course it didn't after having its internal mechanics screwed with by the magnet and being dropped on the floor what they'd have to do is disassemble the hard drive in a clean room and insert the platters into a new drive casing in order to check for data retention

the older hard drives were so much more susceptible to this, as since the amount of data it could hold was smaller, but it was spread all the way along the same size surface, if not larger, that meant the magnetic particles were much more powerful due to the groups of them being larger, thus being more attracted to magnets and probably making it possible to wipe the drive with nothing more than a worn out fridge magnet.

Keh0ol Excuse me, but since the early 90's, it is required by law for a hard drive to be able to withstand 3 G's of force at absolute bare minimum before things start breaking. This one suffered just under a single G of impact, so you could still install a operating system on it after you reformat it with another computer.

try it and let me know,seems like 2010 or older D: have not yet heard the laws....

my brother already has...his whole laptop suffered 4.5 G's of impact and survived with only minor cosmetic damage! This laptop is too small to have any sort of harddrive protection, either!

yes lol

O̥ͦn̥ͦ b̥ͦe̥ͦd̥ͦ o̥ͦr̥ͦ d̥ͦo̥ͦe̥ͦs̥ͦ

doesn't the laptop have to be turn on for that to happen?

Tom Cho in most cases, yes. But as you can see from the video, the laptop hit the magnet at very high speeds which may cause the driver head to physically bend causing the laptop to be unable to be turned on.

By lw requirement, a laptop harddrive is required to be able to withstand the force of at least 3 G's, and has been that way ever since the early, early 90's. In this case, at absolute worst case scenario, it probably only hit the ground at just under 1 G. Even then, some harddrives only claim to be able to withstand this minimum force, but can take up to double the requirement needed.

dropped my laptop of the coffee table, about a foot high, had to replace my harddrive xD

frunlakiso2 That would shake the drive up enough if the laptop weighed more than 5 pounds and landed around the harddrive area.

hi 12

im Damian, nice to meet you

Exactly

+Senpai Films No, it would not. Solid state drives do not use magnetic traces. They use NAND chips. Basically a SSD is a high capacity, high speed flash drive.

water air fire earth fuckin magnets how do they work

+Ricky Salazar gg

And destroy the basic programs your computer needs to preform the simplest tasks in the process, thus rendering your computer utterly worthless.

I would describe using a magnet to wipe a hard drive as more of a 'start nuclear war" approach then a "scorched earth' one.

Danke für die Warnung!

I can do it with a screw driver

I can do this with a nokia

Valdis Volgemuts 👍

i can do it with my mind

pretty sure you can do these without system32, let me fix that for you...
