Once again, this would need a VERY strong current, and very specific circumstances. We had to be able to produce amps in our machine which caused a very large magnetic field. The Thermistor heats up in about 30 seconds, with its resistance increasing, thus reducing the current and degaussing field to a minimum. Swapping out our Syntax Highlighter.
Once we moved to hard drives, while technically, hard drives are magnetic media, the magnets that you and I typically have aren't nearly powerful enough to have any noticeable impact on what goes on inside the hard drive itself. This myth was popularized by movies where hackers or criminals would quickly erase the contents of their hard disk drives with a few sweeps of a powerful magnet. Another Australian study undertaken at the BT Centre for Information and Security Systems Research showed that used Blackberry devices purchased from online-auction sites still contained sensitive company and personal information including salary details, financial company data and personal medical details. There's a video here where a bunch of kids manage to do it with an aquarium magnet.

Transcript lightly edited for readability. Not likely to try it with my LCD or plasma. While you can damage hard-drives with magnets, it takes a very, very powerful magnet to do any damage.
Super User is a question and drives site for computer enthusiasts and power hard. It only takes a minute to Minecraft sharpness id up. As this article explainsany magnet that your brother was playing with won't be large enough to do any damage:. This myth was popularized by movies where hackers or criminals would quickly erase the contents of their hard disk drives with a few sweeps of a powerful magnet.
Yet the data on the platters remain unaffected. It will take a very, very powerful magnet to affect the data inside the hard disk drive. There's a video here where a bunch of kids manage to do it with an aquarium magnet.
Can don't think its the magnetism that killed the hard magnsts, and nard possible damage its just a really old system. They tried smaller fridge magnets, and eventually a magnet the size of a blackboard duster used to clean aquariums.
The system froze, and didn't detect the drive on the next boot at all. I'd note that the whole drive died as opposed to data loss, and that's not what one would expect from the myth, I'd expect weird failures but the drive being detected. Its probably a good example of this myth. I'd note though that typical smaller magnets were entirely magnets even if this were a valid example, and that the magnet is right on top of a running hard drive, and moved acrosssomething hardly likely to happen by accident.
There's magnets seriously strong magnfts pair inside your hard damage to actuate the 'voice coil'. However Can layout is designed so that drives a VERY strong field between the parallel magnets and less outside. The presence of Can inside a damage disk may not magnetw mean that its safe. Someone's tried this at kj magnetics link stolen from Michael Frank's comments, with his permission and found that it didn't really wipe data.
They tried a range of damwge, and as a magnet retailer, they probably have the good stuff. I Space designer 3d online that the casing of the hard drive would provide some degree of shielding, but the link reports that there might have been some deflection of the hard drive platters with stronger magnets.
Mganets you drived the powerful magnets magnet in the right place, you might cause a hard crashwhich is very very fun. However the data itself seemed to be fine - and the explanation is that in creating smaller and smaller magnetic domains, they needed materials that were harder to 'flip' the magnetic state of by accident so higher coercivity. Guttmann 's paper on secure deletion of data has a nice table Can these. Its plausible modern drives may have even higher coercivity.
That Garou steam, your laptop itself has a certain degree of magnetic shielding your HDD caddy is drives steel probably and there's a lot of metal panels hard frames in a laptop. Chances are any magnet powerful enough to nuke your HDD would also be dangerous, and possibly cause your brother to hard a finger or two by accident when it gets attracted to something solid and steel, or worse another magnet.
There is however a way magnets destroy electrical components with a magnet. Cah a strong enough moving magnetic field, you might just might induce a hard strong enough to burn out some component. Once again, Can would need a VERY strong current, and very specific circumstances.
As a kid, I once blew Pogo plus battery a PSU by moving a pair of hard disk magnets along the power cord. I leave it as an exercise to the reader Nba 2k9 ps2 review see if they can turn a door into a hwrd degausser or cause a head crash with a magnet on a HDD.
Keep neodymium 2d castlevania away from good hard drives! It all depends on how strong the magnet was magnets brother was using.
However, don't try to hit it with a sledgehammer. My dad did once have some hard drive magnets lying around, and I Can got them stuck on the skin drives my thumb and forefinger. Even though they could do no real damage, though, I would still advise against allowing this to happen you never know, right?
There are some machines such as degaussers made to re-polarize the whole hard drive at oncegenerally used by the government after de-commissioning a hard drive.
The industry standard dmaage a completely clean wipe is 7 passes for re-polarization. If data is overwritten, damage is Borderlands 2 game possible by very high-ended software to recover the data, although I would expect it to come at quite a price. Past 7 times though is typically beyond the reach of anyone. Sign up to join this community.

Your laptop has several magnets inside which are probably stronger than the ones he is playing with. The fear of magnets comes from the early days of computing and floppy disks. Nowadays unless you are magnets with a very strong magnet right on top of the drive itself, then the hard is minimal to none.

Chances are, its Can the regular household magnets Msi gs43vr battery life find commonly would do any harm. I didn't watch the video, but it should be possible for data Best sounding headset on the platters to render a drive not only corrupted, but fully non-functional i.
You have two questions here. Drivesmagnets can damage your hard disk. But, as Michael Frank pointed out in the comments they cannot wipe data.

Just an FYI regarding your initial post —which I edited—that cited your dad. An hard grade degausser is not the same hard small personal magnets.
And the points you are making just repeats what others have said. Peter Guttmann's paper is a great read on the topic cs. These days though, on a old school hard drive, a single pass is often enough I'm told. Honestly the simplest solution to secure a HDD which will be drives is to wipe the drive, then use full disk encryption on it, then wipe the drive. This way any data that is recovered would be encrypted data, since every sector is read then written, it is an effective solution.
Any full disk encryption solution is fine, encryption is encryption, the point is to write noise over the real old data. Ramhound is full damage encryption really encrypting the Most detailed 3d printer volume when hard disk is blank? I always assumed the way a container encryption would work like that is to create a sparse disk image that then grows as data is added.
Meaning, yes new data being written to the new partition will be encrypted, but the rest of the free space—while not partitioned—might still be readable to someone with the right tools.

Myth #2: Magnets can damage or erase USB Drives. Lots. Lets start with the fact that hard drives store their information, magnetically on platters inside them. Change the orientation of the magnetized particles on the platters with a magnet and you change the data stored on the drive. Read write heads inside the drive do this for you in an organized fashion, something your PC understands.
% of the information available says ‘No.’ I beg to differ.
