The problem with his method is that each time he tried a small magnet, he did not check the hard drive for data corruption. The hard drive only reads once you load up something not stored in the RAM yet, but on the hard drive. By doing a reboot after the car magnet test, he was actually testing the hard drive while he had not been doing that before.
@@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
@@dont-want-no-wrench Nah. "All information has been gone" meaning even the servo data and stuff needed for the drive is gone. the drive doesnt even detect thats why it showed no hard disk
+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.
In the first part of the video, when he holds the magnets near the hdd and expects something to show on the screen is bogus. once the OS is loaded into memory you could actually remove the HDD completely and the desktop would not be affected until you try to actually do something like click on something. If he actually tried to reboot after holding that large hand held magnet near the HDD I am pretty sure there would be a problem.
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.
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.
The first few tests didn't seem like they were done properly. He should have put some pictures and documents on the hard drive and checked them after every test to see if the drive was failing.
dear british guy, if you don't command your pc to read-write any data you wont notice anything wrong with the drive just by sitting there idling while playing with your magnet, everything you see onscreen is already on ram, try doing that and then browse through a folder full of pictures or something, only then you COULD see corrupted files

+Joseph K (JoeDKat) I assume that you're sighing because it's so *rare* (and reassuring!) to see the *correct* term used (reorientated), instead of the usual, incorrect term, i.e. "reoriented"...?
Would have been interesting to see where the line between messing up the data and not was, instead of leaping past it. The experiment was also sullied by the laptop striking the magnet, as impact forces of that nature can influence the effectiveness of a magnetic force being applied.
Maybe I'm mistaken but you would not be able to tell that the Hard Drive was erased until you tried to load something into memory (RAM). Meaning that the Hard Drive could have failed on the first test, but we would not know because he some how just expected it to have a pop up. The only reason that the final magnet seemed to work was that he turned off the laptop and thus dumped the RAM. Then when it tried to load Windows back into RAM it could not find anything on the disk.
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
Actually, taking the HDD out and using a magnet around 120-150 on the gauss scale in a circular pattern, will erase the HDD. The trick is to have a magnet below that is stationary and one above moving in a side to side or circular pattern. You can also re-use the HDD providing no real damage was done. The trick to their safety is the coating process used to coat the internal disc. It's almost glued onto the spinning disc.
Here's the issue w/ his little magnet that "didn't work": it was powerful enough, the operating system was just stored in RAM and nothing on the operating system was changing at that time. For instance, if you were to open Program A before the magnet, that information would be stored in RAM. If you were to place the magnet and open Program B, it most likely would not work as the data would not be in RAM and would have been erased from the hard drive.
They should have tested the hard drive for damaged files after every test, as the magnet could have damaged other files on the pc that he wasn't currently using.
***** 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.
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.
Oh wow, it doesn't boot up after a magnet hit it yet it still runs while a magnet is hitting it? someone didn't bother actually doing any real work did they? -.- OS is stored in RAM when running.. not HDD... so no sir, it would NOT just "instantly" stop working and fail -.- Now if you got it near the RAM sticks, it 'might' but most have electricity running through them, soooo it'd negate any actual effects
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.
***** 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
I remember when I was in 4th grade we had an Apple IIe in our classroom. Some kid who didn't know any better was holding a relatively small magnet when he went to have his computer time. He was a couple of feet away but the screen went bright green and the computer just blinked off. The teacher saw the magnet and freaked out. Luckily it fired up and went back to working like normal right afterward.
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.
this reminds me of Breaking Bad...when they had to erase a laptop's memory because it had a recording of Walter and Jesse breaking into the place....they used a giant magnet inside a truck lol
back in 6th grade my friend had a dsi, and I was into Bakugan; the magnets in the bakugan were strong enough to make his DS restart if I put it over the left side of the lower half of it
leaving just a weak magnet close to your harddrive for longer periods of time does indeed corrupt information, it doesn't have to be instant as said in the video
i've done it before, with a magnet found in an RC car's motor, and i can say, it was less powerful than his second magnet, the reason it didn't do anything is because he was going too slow, you need to swipe it rather swiftly across the hard drive area, usually underneath is the best. and it will wipe it, I've tried, and I've succeed
+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.
HDD's have data stored in millions of sectors, it's possible to have sectors where program data and operating system files stored be left in tact while sectors containing personal files are corrupted (and vice versa) and he wasn't launching the start menu each time, it just happened to be up during the larger magnet test.
What could cause a box full of floppy disks and a hard drive to spontaneously be wiped overnight? My family lived a mile or 2 from a radio tower. Can those transmissions corrupt magnetic media? Speaking as a person whose work was wiped more than once as a kid.
Just because you don't immediately see any effects doesn't mean data isn't being corrupted! A real test would have to involve checking the drive for faults.
I dont think that the wipe out is caused by the magnet, rather, it is caused by the force of the laptop smashing against the electro magnet. I think it is caused by a head crash or bending of the head.
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.
Was he even using the hard drive while he was rubbing the surface of the laptop with the small magnets? As I understand, after POST, BIOS searches for the MBR and proceeds to load the OS into RAM. So, leaving the PC just idling at the desktop wouldn't tell us much about the moment when the actual damage began to occur since the OS isn't trying to access the HDD. There should've been a series of exhaustive drive tests for each and every magnet type used in this video. As it stands, the conclusion to which this video arrives to, seems very unreliable to me.
The OS is almost constantly reading and writing to the harddrive. It's called Swap Memory. But I'm almost 100% sure, that the computer had data damage from the second magnet. They didn't run any tests on the harddrive afterwards.
the dropping of the laptop doesn't seem fair to me, it could be the reader of the disk would have hit the surface of the disk, damaging it so bad it wouldn't operate, though that is my opinion, i sure do believe the magnet played a role too
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.
You need 2 Magnets, with different Poles. After that take in every hand one Magnet. One magnet from the bottom the other from Top. if the Magnets are react decrease the range between both Magnets after that increase fast the range between magnets. If you do it right, you will here a really tiny explosion. If the HDD cant be read you have succesfully performed a "EMPinch". Can also be done with powerful Firecrackers. Fire Detonations can also produce a Pinch.
you dont need that powerful ! i ones droped 5 W speaker on harddrive and data was lost forever,since then every time i work with hard drives,i make sure that the area is safe
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.
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!
All my porn Is gone. This is not a joke. This is a serious issue and if he goes around spreading his propaganda. Well lets just say. Goodbye to everybodys porn.
I'm assuming you're just messing around, but if you're not, he was listening to see if he could hear the hard drive spinning. When the hard drive is powered on you will hear a slight humming type sound if it is in healthy shape. If you can't hear your hard drive spinning while it's powered on that's a good indication that it's dead.
+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.
You can pretty much unplug the hard drive from the computer once the OS has been loaded to the RAM, and the computer would not know the difference until you had to reboot, therefore he could have damaged the hard but would not have known this until he rebooted the computer. More then likely he damaged the hard drive with the smaller magnets. This guy doesn't know jack$hit about computers.
Because of the photo they took at the end - the data was striped, symmetrically, across the whole disk. A shock from when it dropped / got picked up would screw up a moving component, not the actual magnetic areas of the disks.
When i was little, my dad had one of those really big moniter/screen computer thing (the old type of desk computerthat isnt mobile). When you place a magnet on the screen and drag it across, the colors would be distorted and create pretty rainbows
Cake Gaming the OS is on the hard drive its also wiped, what I think you meant is the bios which is on the motherboard stored in rom or in flash memory
the smaller magnet might only damage a small part of the hard drive, the only real way to check the damage is to open every file on the computer. just because the computer turns on does not mean that the magnet had no effect it just means that the crucial files are still intact
Yes, I knew that. I helped a friend with his huge water truck. I asked him if there were any magnets anywhere around the truck, he said, "Hell yeah!, that's what we use to transfer water systems." I asked him if his truck was computer operated. He said yes. Problem solved. This huge truck had been in and out of working order, and they couldn't get their jobs done without it. And no he didn't pay me! LOL! I didn't do it for money. Just glad that he got his problem solved.

Hello John :D
this reminds me of Breaking Bad...when they had to erase a laptop's memory because it had a recording of Walter and Jesse breaking into the place....they used a giant magnet inside a truck lol
Well, that was not an electron microscopy picture. That was actually a magnetic force microscopy (MFM) picture.
actually the medium DID scramble it but you have to reboot for changes to take effect
back in 6th grade my friend had a dsi, and I was into Bakugan; the magnets in the bakugan were strong enough to make his DS restart if I put it over the left side of the lower half of it
he has steam :D 1:53

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.
leaving just a weak magnet close to your harddrive for longer periods of time does indeed corrupt information, it doesn't have to be instant as said in the video
Woo... I don't even want to dare swallowing 2 magnets...
Yer ded, returning with the English trans in a few months
lily-liver Shit, I would have never thought of that. Disturbing way to die, perhaps. Has anyone suicided by swallowing magnets..?
+lily-liver unless you got close to any steel object
+Seiko Shinohara Just.. stay away from nooses ;n;
I watched this on my television 6 years ago, now its on YT 7 years old video omg how time flies
But the magnet wouldn't effect your RAM and therefore what's on the screen until you changed what's in the RAM.
Did you guys use an old enough computer here???? That drop alone could have killed it.
Good thing I've got an SSD on my laptop so not even magnets can wipe all of my encrypted hentai.
Encrypted hentai is best hentai
That fucking profile picture fits that comment
Why use an acid and a hammer, when a good electric spark can do the job?
i've done it before, with a magnet found in an RC car's motor, and i can say, it was less powerful than his second magnet, the reason it didn't do anything is because he was going too slow, you need to swipe it rather swiftly across the hard drive area, usually underneath is the best. and it will wipe it, I've tried, and I've succeed
Why didn't he use neodymium magnets
+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
The other weaker magnets may have corrupted some files but not enough to bring the whole system down instantly so I'd still want to be cautious.
its ok it was running windows XP anyways
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
V E R TX i feel bad

HDD's have data stored in millions of sectors, it's possible to have sectors where program data and operating system files stored be left in tact while sectors containing personal files are corrupted (and vice versa) and he wasn't launching the start menu each time, it just happened to be up during the larger magnet test.
What could cause a box full of floppy disks and a hard drive to spontaneously be wiped overnight? My family lived a mile or 2 from a radio tower. Can those transmissions corrupt magnetic media? Speaking as a person whose work was wiped more than once as a kid.
Maybe
Just because you don't immediately see any effects doesn't mean data isn't being corrupted! A real test would have to involve checking the drive for faults.
Neodynium magnets do not need to be car sized to fuck your computer.
True, they are also cheaper than the last magnet used.
Good idea jessy 😄
LOL
I dont think that the wipe out is caused by the magnet, rather, it is caused by the force of the laptop smashing against the electro magnet. I think it is caused by a head crash or bending of the head.
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.
I remember my firsts computer classes [20+ years ago] and how we still use floppy disks. The first thing we learn is to not approach magnets to them.
Was he even using the hard drive while he was rubbing the surface of the laptop with the small magnets? As I understand, after POST, BIOS searches for the MBR and proceeds to load the OS into RAM. So, leaving the PC just idling at the desktop wouldn't tell us much about the moment when the actual damage began to occur since the OS isn't trying to access the HDD. There should've been a series of exhaustive drive tests for each and every magnet type used in this video. As it stands, the conclusion to which this video arrives to, seems very unreliable to me.
ya but the ram needs the hardrive to do anything
That laptop looks really OP! It's so modern
He got rid of all his porn
rip cheese pizza
The OS is almost constantly reading and writing to the harddrive. It's called Swap Memory.
But I'm almost 100% sure, that the computer had data damage from the second magnet. They didn't run any tests on the harddrive afterwards.
I want to watch a video that answers the question in 3 sec: yes or no
+Alex Mallen that's why I'm looking at the comments in stead of the video
I do the same thing
Reorientated. Brilliant.

before some years, it was my favorite show on tv
the dropping of the laptop doesn't seem fair to me, it could be the reader of the disk would have hit the surface of the disk, damaging it so bad it wouldn't operate, though that is my opinion, i sure do believe the magnet played a role too
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.
You need 2 Magnets, with different Poles. After that take in every hand one Magnet.
One magnet from the bottom the other from Top. if the Magnets are react decrease the range between both Magnets after that increase fast the range between magnets. If you do it right, you will here a really tiny explosion. If the HDD cant be read you have succesfully performed a "EMPinch". Can also be done with powerful Firecrackers. Fire Detonations can also produce a Pinch.
you dont need that powerful ! i ones droped 5 W speaker on harddrive and data was lost forever,since then every time i work with hard drives,i make sure that the area is safe
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!
Why does the laptop have steam on it?*pause on **1:58**, you will see it on the START BAR*
This video is fake. I tried it and now I have no computer.
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;)
All my porn Is gone. This is not a joke. This is a serious issue and if he goes around spreading his propaganda. Well lets just say. Goodbye to everybodys porn.
+ANDROUMAC1 its*
***** I cant buy anything with a nickel. Raise the price.
How did you manage to comment then:)?
Imagine fighting robots with swords made of magnets.
when you download porn and you can't delete it
hello son
***** oh shi- I mean hi dad I swear I didn't watch porn
WTF XD
I heard what you're talking about ( ͡° ͜ʖ ͡°)
Who downloads em these days?
I'm assuming you're just messing around, but if you're not, he was listening to see if he could hear the hard drive spinning. When the hard drive is powered on you will hear a slight humming type sound if it is in healthy shape. If you can't hear your hard drive spinning while it's powered on that's a good indication that it's dead.
Would it have the sane effect on a SSD?
+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.
Stinger Bee Cool!

More ideas on how to get rid of hard drives
You can pretty much unplug the hard drive from the computer once the OS has been loaded to the RAM, and the computer would not know the difference until you had to reboot, therefore he could have damaged the hard but would not have known this until he rebooted the computer. More then likely he damaged the hard drive with the smaller magnets. This guy doesn't know jack$hit about computers.
hi 12
im Damian, nice to meet you
Exactly
I remember Walter in breaking bad had a dial which went up past 250
We've all seen breaking bad
Because of the photo they took at the end - the data was striped, symmetrically, across the whole disk. A shock from when it dropped / got picked up would screw up a moving component, not the actual magnetic areas of the disks.
lets do this against robots
Now people know how to get away from incriminating internet searches.
This reminds me of jessie and heissenberg breaking bad.
yes lol
ok from now on ill go to a scrapyard when i want to format my harddrive thanks natgeo
Dam it! I have tousands of those electromacnets in my back iard!
What's an iard?

Andrei Tache
Oh you meant 'Yard' :p
yes,that's what I meant =)
Yup,better note that... already broke twelve laptops =P
When i was little, my dad had one of those really big moniter/screen computer thing (the old type of desk computerthat isnt mobile). When you place a magnet on the screen and drag it across, the colors would be distorted and create pretty rainbows
SSDs oh yeah
It might have wiped the drive but the OS still works, which means it's not dead.
Cake Gaming the OS is on the hard drive its also wiped, what I think you meant is the bios which is on the motherboard stored in rom or in flash memory
lol he has steam
the smaller magnet might only damage a small part of the hard drive, the only real way to check the damage is to open every file on the computer. just because the computer turns on does not mean that the magnet had no effect it just means that the crucial files are still intact
Breaking bad?
This is the moment where jesse said magnet
XD
Fucking magnets, how do they work,
Look that song up on UA-cam
damnit icp
water air fire earth fuckin magnets how do they work
Well, considering that you opened the hard drive, pretty much muffed it up in the first place.
Finally I can get all the porn virus out of my pc
+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.
He went from a strength of pebble to couple of rocks to a massive boulder to crush the hard drive.
Well this was stupid.
Danke für die Warnung!
Yes, I knew that. I helped a friend with his huge water truck. I asked him if there were any magnets anywhere around the truck, he said, "Hell yeah!, that's what we use to transfer water systems." I asked him if his truck was computer operated. He said yes. Problem solved. This huge truck had been in and out of working order, and they couldn't get their jobs done without it. And no he didn't pay me! LOL! I didn't do it for money. Just glad that he got his problem solved.
