magnet in harddrive| geek_tylosand | March 25, 2008, 2:34 pm | #1 | | Magnet in harddrive I thought it would be fun to try extract the rare earth magnet from a harddrive however I dont have any faulty harddrives to pull apart so i figured i'd just buy one off trademe.
Are all the magnets in harddrives the same or do harddrives with bigger capacities have more stronger magnets? |

Any magnet in close proximity to a hard drive will destroy all data on that drive. | | geek_swivel | March 25, 2008, 2:56 pm | #3 | | Pass Not sure, will be keen to know | | geek_swivel | March 25, 2008, 2:56 pm | #4 | | Oldman Hard drives have a magnet in them | | geek_chapadao | March 25, 2008, 3:15 pm | #5 | | Maybe you could go to a computer repair shop or somethin in your area? These magnets are cool lol I pulled some out of a couple drives, they have 2 in each and are sooooo strong. They will stick together through your hand. or hold several sheets of cardboard to the fridge | | geek_ross1970 | March 25, 2008, 3:28 pm | #6 | | They are neodinium magnets ( yip also known as rare earth ). There are some cool clips on Youtube using them for, amongst other things, making simple electric motors using a AA bat, one neodinium magnet and a piece of wire. | | geek_ross1970 | March 25, 2008, 3:59 pm | #7 | | Here's one... http://tinyurl.com/ypcqjs | | geek_pc_nut | March 25, 2008, 4:12 pm | #8 | | Re#2 true magnets will mess with the coating on most magnetic disks etc however it would take a magnet strong enough to pull iron out of your blood to erase any hard disk and the magnet that moves the head mechanism is comparatively miles away and wouldnt affect the data | | geek_mrfxit | March 25, 2008, 4:53 pm | #9 | | Magnets from sub woofers Are pretty good. It's the magnet from the center cone. You can stick small note books to the nails in your walls with those little buggers | | geek__sexylady_ | March 25, 2008, 5:07 pm | #10 | | Lol i have about 800 platters here that we & friends have pulled from various HDD's over the years, are going to make things out of them, we have also got a few maganets as well, very handy little bugga's (wish we had kept more of the maganets though! | | geek_mrfxit | March 25, 2008, 5:52 pm | #11 | | LOL Sexy . . . what are "maganets" Got a crate of hdd's listed at the moment. | | geek_xpdnz | March 25, 2008, 6:40 pm | #12 | | Lol @ #2 All floppy and hard drives have magnets, hence the term "magnetic storage" :) | | geek__sexylady_ | March 25, 2008, 6:49 pm | #13 | | Hehehe Mrfxit i have decided to rename everything to how my fingers WANT to type things not how they SHOULD be typed... sick of re-reading the crap i type for future reference Maganets = Magnet, jsut = just etc. | | geek_mrfxit | March 25, 2008, 7:05 pm | #14 | | LOL Sexy, yae tahts teh wya xpdnz, the 5.25 floppy drives have some pretty good magnets in them. | | geek_gyrogearloose | March 25, 2008, 7:53 pm | #15 | | #12 - magnetic storage is so-called because the data is being stored on the media by virtue of the magnetic orientation of some part of the media. The magnets inside the disk drives being described above are part of the head positioning mechanism. The actual data is written to these disks using an electromagnet. Core memory, being another example of magnetic memory, has no permanent magnet because there is no read/write head to position. | | geek_0800xford | March 26, 2008, 2:32 pm | #16 | | .... i dismembered a hard drive a couple of weeks ago for the magnets, 'dangerous' stuff ;) | | geek_bitsy_boffin | March 26, 2008, 2:37 pm | #17 | | ... Just watch your fingers when playing with hard drive magnets, pinching skin between them when they snap togethor is not pleasant :-) | | geek_0800xford | March 26, 2008, 2:40 pm | #18 | | .... i agree! ha ha | | geek_spj2 | March 26, 2008, 2:44 pm | #19 | | #6 i think you mean neodymium but yea. http://en.wikipedia.org/wiki/Neodymium | | geek_ross1970 | March 26, 2008, 3:16 pm | #20 | | Yeah thats the one, neondenimon. | | geek_gblack | March 26, 2008, 9:26 pm | #21 | | Bigfoot hardrive they are a classic - the magnets are huge compared with the ones from a 3.5" HDD. Clamping two together, most people could not pull them apart.. and yes, its fun have them clamped either side of your hand but they can bite you ;-) | | geek_tylosand | March 28, 2008, 9:19 pm | #22 | | .... hah I must say the platters look pretty cool, and the magnets are so powerful, I thought it was initially attached to another harddrive part that was made of steel but figures out it was just attached, Funny this was when I tried to open it the screws I found out were the Torx type , I only managed to get 1/3 out by using a - screw, I proceeded to try and pry it open with a screwdriver but that didnt work either. In the end what i did was use wirecutters to completely cut off the metal casing from the parts of the case that had screws attached, lol Kind of a reverse process from taking the screws out. Taking everything but the screws out. | | geek__sexylady_ | March 28, 2008, 9:26 pm | #23 | | Lol yes the platters are cool my partner used to make lamp stands and shades out of the bigfoot platters, have not got any of those left but still have hundreds out of the 3.5" drives | | Leave your comment: | |
