why am I doing this aside from it being totally intoxicating well because these old server drives behind me are loaded with data that is so sensitive that I am legally obligated to destroy them since we're at it anyway I thought I'd show you guys the atrack Mobile Data Destruction system here complete with dealing magnet and hydraulic press when this thing's done with your drive you will not be getting anything off of it but lonus you might say what about an SSD oh that's got to hurt turns out it can do those too but lonus you might say think of the turtles or your staff I need hard drive couldn't I just erase them and sell them maybe at a nice discount the answer is yes but also more complicated than you might expect there are a lot of ways to erase data and they're not all created equal kind of like my Segway to our sponsor xplit level up your live streams with simple yet effective broadcasting and video production tools for use on platforms like twitch and YouTube check out xsplit at the link below and use code Linus for 9% off your first purchase or subscription nice a quick search of eBay will reveal tons of listings for used magnetic hard drives so clearly plenty of folks out there are taking the wipe and resell approach but as you probably already know just hitting delete and emptying the recycle bin is not a secure method of erasing data and even a format doesn't necessarily make everything on a storage device unrecoverable just check out the results of of using test disc on an SD card full of deleted text files if you don't believe me so to prepare a drive for sale you need to do things right pun intended because the simplest method of doing that is to write zeros over the entire disc then you want to go back and read it to ensure that there's nothing but zeros to be found it's quite effective at preventing someone with a simple piece of free software from recovering all of your as recipes but what if you're a bank or hospital or the CIA well the answer there is it depends in the past Nells could conceivably use a technique called magnetic force microscopy to pull data off of a drive that had already been overwritten the idea behind it was that not every right operation on a particular bit of storage would be lined up with exact precision on the disc we're going to have a couple of papers in the description linked down below it's super interesting stuff and this potential attack Vector led to a series of data deletion standards that would call for between three and three dozen passes riding over the drive alternately filling it with zeros then ones then random characters or even predefined patterns with modern hard drives like these ones however the components and the tolerances have shrunk so much that the possibility of fragments being left behind that could be read is basically zero so new standards like nist 888 have come along which now say that four storage devices containing magnetic media a single overwrite pass with a fixed pattern such as binary zeros typically hinders recovery of data even if state-of-the-art laboratory equipment is used to attempt it so you're probably thinking if anyone with a computer could could do that at home why is this machine still necessary well the issue is doing it at scale you see with great capacity comes great right times so even drives that have built-in ATA secur race commands which should be anything made after about 2001 can take hours or even an overnight operation to fully clear and if you're that hypothetical bank or three-letter agency you could have hundreds or even thousands of drives to sanitize and dispose of nobody got time for that I mean even if you were willing to pay some Junior IT Tech to wipe drives all day every day buddy better have the appropriate clearance to handle it and even if they do something is eventually going to slip through the cracks like like that one time when my former employer didn't wipe their employee records yeah yeah good times I mean that was bad enough but hey look imagine if the data slipping through the cracks was I don't know a list of your nation's covert intelligence sources in North Korea or something that is where the Mobile Data Destruction system comes in it's fast enough to process Mount hard drive here that's another fun dad joke in about an hour and the first stage is the deusser and this bad boy is no joke we all know that hard drive storage is magnetic but what a lot of people don't realize is that this is perfectly safe you would need a much stronger magnet than anything you'd find on a screwdriver to do anything to a modern drive and there are a lot of different ways to skin this cat but this particular unit builds up an electrical charge in its capacitors then discharges the energy as one big highfrequency electromagnetic pulse so long as that pulse is stronger than the hard drive's coercivity that is its resistance to Magnetic change the pulse will randomize the polarity of all the little magnetic bits wiping out the data permanently and this is really important the drive doesn't need to be functional for the deaser to be effective you guys ready this bad boy puts out a field of about 10,000 gaus which is about double the coercivity of both conventional and shingled hard drives there it goes meaning that aside from the data itself being gone all the tracks on the platters will be destroyed and anecdotally we've heard that it can even shift around internal components or demagnetize the permanent magnets in the drive it's kind of the uh nuke it from orbit option it still looks perfectly normal but this drive is now completely unusable which raises a question why do we need the rest of this getup here well modern privacy and data protection laws require a more systematic approach and the mdds is more than just a dealer and a Crusher on a cart let me show you guys the workflow we start by scanning in the serial number of our drive then placing it here to take a before picture atrack is working on an AI module that will just read the serial number from the picture but that's not ready yet then it pops into the deusser we've already hit this drive once but doing it again isn't going tot it any more than it already is run right now it's charging up its capacitors then it's going to take all that power and I don't know if you'd call that an electromagnetic pop or thunk does anyone around here got a pacemaker no oh good probably should have checked that before we started but everyone's still standing I think we're all right atra says that we should only measure about five of this units 10,000 gaus directly above the unit where the shielding is weakest that could potentially impact older pacemakers but that's within the occupational safety limits for short exposure so should be fine after the thud we wait for the Raspberry Pi controller to pop up once this readout says success the data is gone but this next step is still important for a few reasons one it gives us an obvious visual indicator that uh this thing ain't going to work no more two the more extreme data protection standards do still call for physical construction and number three this is the most important it's super fun to watch oh you doing okay buddy it didn't go it's not it's in there the right way I don't want to not follow the instructions did I put it upside down or something matter destruction fail open door oh this is a helium drive this is a sealed drive we spoke with at Rack about the difficulty that we had crushing these beefier unibody hard drives and it turns out the crusher in our cart was modified if IED to run on 110v Power and as a result doesn't have quite the same oomph of the production units at Rack picked up a few of these drives to double check and their production unit made short work of them once the drive is crushed we shake any loose bits out into the drawer down here throw it back under the camera for an after picture and all of that gets logged to atra's redundant Cloud servers and then you can print off a certificate of Destruction for your local records kind of wonder what else we could crush in this thing that would make a great Floatplane exclusive maybe uh yeah we'll have the social team do that lg. g/f flat plane coming soon that aside I can practically hear you guys saying L is what about ssds don't worry we're going to get to that but first we need to at least mention new magnetic hard drive Technologies like heat assisted magnetic recording or hammer in a nutshell these Cutting Edge drives achieve much greater storage density by using platter materials with much higher coercivity as you can imagine from when we were talking about about the deusser this helps to prevent accidental flips to nearby bits when they're exposed to the right head but it presents some other challenges like well how do you intentionally write to the bit you're actually targeting it's super cool in less than a nond they heat the target bit up with a laser to around 450° C which reduces the coercivity then they it and rapidly cool it back down to lock in the data at this time we're not aware of a deusser that is capable of clearing a hammer drive yet but we're told that they are in the works so for now a drive Shredder might be your best bet for Hammer at Rack told us they're working on a shredder attachment for this unit and if you guys are into this stuff I would love to get our hands on it and show it to you now let's finally talk about ssds and all your other non-magnetic storage the deuser isn't going to do Jack squat to these either and overriding them might not be Totally Secure either if the drive uses automatic wear leveling which pretty much any modern consumer SSD would as with hammer drives then that leaves you with secure Ras which at least is refreshingly quick on an SSD and if properly implemented should be good enough for anyone to resell the drive without worrying about recovery but in cases where you have to be 100% sure that nothing's getting through the cracks our Crusher has a cool little accessory that not only crushes the drives but also ensures damage to each and every memory chip on the board that's scary looking let's give it a try all we got to do is pull out the hard drive attachments okay put this bad boy in here H yeah something like that seems legit you want to see a 2 and 1/2 in or an m.2 yes all right right well let's start with one of the I mean not the heck it could probably do both here we go sayara buddy oh oh there we go did we get all the chips let's see let's see oh wow I mean the whole board came in half that's probably a good sign Nan chip dead nand chip in half other more different Nan chip that's not quite half but that's definitely some fraction the controller survived but there's no data on there last n chip definitely dead now how about this boy oh okay well there's one n chip I think it's dead obviously we are talking thousands of dollars in the hardware alone not to mention the software and integration work around this whole process and the Redundant servers around the

that regulations is regulations at least until we can change them and I do get it even if I don't like it oh there's one more thing we should touch on let's talk about seds or self- encrypting drives
