I like that you’re honest. Most data recovery service dudes will act as if opening your hard drive will cause permanent damage just so you can call them for help and pay up.
These fucking data recovery dudes are mad pei , they let down all of your hopes and asking stupid questions and doesn't have guts to except the challenge , ones they heard about you did open your hard drive ,that's it " I am not touching it " world end up, life is under the thread , I am dying , I m blind , I say keep opening bloody hard disk ,you one day learns things.
can you be more specific? Sounds like by "data recovery service" you mean that guy in the video.
@@khurramsa5133 Why did you open your hard drive?
y’all delusional and cringe 🤣🤣🤣 guys at kroll ontrack could recover anything u just dont know shi bout data recovery
because in the shell is their treasury
the disk is now history, and you are the best history teacher ever. Thanks dude.
Fascinating to see how these devices work. They are more fragile than I thought. My WD drive is well out of warranty. I think I will crack open the case and see if the platters are intact since I have no idea what caused my drive failure. Thanks for the tech lesson!
I am sorry it couldn' t be repaired, but thank you for showing us the internal mechanics of the hard drive! That was really interesting!
It is possible to recover data from a hard drive with this type of damage. You won't get information that is on the damaged part... but all other areas are recoverable. You just have to have data recovery software that will ignore the read error that you will get when it gets to the end of the drive... Basically, since the heads are damaged, they would be replaced... You will see what you can get before the new ones get damaged, replace the heads again, and start reading again... As long as you get a set of heads that survive going over the damaged area.. you'll get everything on the inner part of the drive that isn't damaged. Which from your video is about 90%-95% of the data.
The alignment issues you are talking about are with the platters being aligned with each other.
When you replace the heads, you use paper to keep them from crashing on each other... you then remove the paper seperaters as you seat the heads on the HDD platters.
Which kind of software? Any recommendation, Welcome. Thanks
no if the controller can't pass the POST!, that kind of damage is a dead one. Atleast not using the original controllers, but a hacked one
no the damaged area would just damage the new set of heads put on the system, Also where it reads to seek and read track 0 is messed up, so it will never be able to become ready UNLESS u turn the head off that reads that platter unless all the platters have that damage.
In a case like this a live PCB swap could do the trick - see the presentation from Scott Moulton ad DefCon15.
This is so satisfying, i would watch this before going to bed.
The best explanation for this process I have seen so far!👍👍
Excellent video of what to do, and what NOT to do if attempting this type of repair.
How cool was to watch this vid... made with patience, care and taking us with you in the curiosity of checking every single piece... thank you for the trip, congrats for a great vid!
Thank you for the extensive video. It was indeed informative and fascinating.
So the noise coming from my computer is where I thought it was. Thanks for showing us this video.
Thanks for this vid. Gives me a better understanding of harddisks.
I am watching the third video of your hdd help and I am asking my self why I didn't open any. Thank you for inspiration and for lot of helpful informations! :)
Nice video with good explanation delivered with patience. I liked everything but liked most the bit where you made effort to improve camera focus so the heads became clearly visible.
The worked for me after two pc shops refused to open the unreadable hard drive. as soon as I opened the case and saw it wasn't in a parked position I figured it was stuck and rotated counterclockwise the disc while dragging the reader head back to parked position and that fixed it. Thanks for sharing!
Well, and then, what happened ? Could you recover everything ?
How long did it work properly after that quick and dirty fix ?
@@idiosyncrazy1980 For an even dirtier fix put the drive on its side and give it a bump into a table. Worked for me, got the drive going but I thought it would work again after that which it did not.
Appreciate what you took time to show us.
Very Informative....Thanks for your time !
THank you so much man! I don't know yet if this will work for me, but thanks for explaining what are REALLY the risks to open the HD... vs almost all experts as you said who just say "no ! don't try !!!! you gonna lose all!!"
very good information. i am a newbie and had no idea why my drive was making that exact noise
I really like the way you demonstrate, I subscribed to your channel right away..
Thanks for posting. Just for folks to be aware, if you intend to open a HDD, you need to do it in a clean environment. Airborne dust is sufficient to cause problems when it settles on the platter. Finger prints on the platter are a disaster. Cover your hair and clothing, wear neoprene (or touch sensitive) gloves. Generally parts (such as heads) are not interchangeable. If there is annular scoring as in this example, other tracks/ sectors may be readable. If he scoring is a spiral, that crosses all data tracks and renders the drive scrap metal. You need good light and the steady hands of a surgeon. :) :)
Thank you so much, absolutely fascinating, . Now I can reasonably know what the hard drive on my laptop would have looked like after it crashed some years ago. That too clicked.
Cheers
Amazing info! Thank you very much!
I have a ~7 yr old Seagate Barracuda 360GB hard disk, that fell sick few months ago (dunno how, never fell down or something). Luckily, i got a new WD 1TB on time and transferred 98% data safely to the new hdd. I was not able to run it for more than 20-30 mins (temps going 45C+ then BSOD) till 2 days ago when i discovered that it is making one clicking sound then fails to be detected at startup.
I just backed up my data before the hdd died totally.
That's because you're Batman!
Arvin Ardakani
Well, you know.. being billionaire, having batcomputer, and being batman... still have to face common problems :S
Mine is making that same clicking noise too. I was able to recover some data from it but it seems my photos are lost.
@@trulygrateful7217 Ah! :(
Informative video..
Good job..
Keep it up and continue for learners..
Thanks..
Jzakallah..
Actually, the read heads are somewhat easy to replace. They have sort of a springy head so the reader can be repelled by the individual magnetic pulls. That springiness also allows for flexibility between platter thicknesses. and that thing about the formatting, all read heads I've seen are the same, they all same amount of turns in the copper coil, and no chip. This means the only electronics in it is the ribbon wire, coil, and heads. The chip that controls the movement is either on a board inside the enclosure, or on the outer board.
To make a long story short, just unplug the reader, unscrew the plastic guide thing that keeps the heads from going too far from the platter, remove the top neodymium magnet, and remove the read heads.
Installation: Unless you plan to save the platters, you don't have to worry about scratching them when removing the heads, just don't let it touch the ones in the new drive. To install them, just do the same thing to remove the damaged heads, then slide the new ones into the plastic guide and screw it down and it should be good to go. Just don't forget to put the magnet back and plug the read head in to the board.
Edit: Nvm, I guess there's more to it then that: czcams.com/video/J9P4UadRdNA/video.html
Well, I was mostly right.
have a disk with me to know what happened to it and it no longer works and I want to fix it in the strongest coefficient where it is, I want what is inside it, it is very important to me, Can you show me the strongest coefficient for it
Wow, that's awesome. I'm thinking of doing this myself so I have got questions. Will it work if I swap the head using the same model, size, first 3 digits of serial number and same firmware version?
If it will work, can I use hddsuperclone to clone the hard drive or I still have to use PC3000??
It's always interesting to know the expert's opinion.
Yes, but you did not hear one in this video ! :^p
I recently discovered your channel to see if I could possible save what I thought was a stuck head on my 2TB HDD and I was confident in opening the drive and unjamming the heads until I found out that all three of my platters had 3-5 rings of very deep scratches...moral of the story: remove your HDDs before transporting a PC
nah, if you shut down the PC the heads should go into the "parking space", where small vibrations are not going to damage them.
I have a Samsung 2.5" HDD, it literally flew and fell on hard floor (turned off), and then... it still worked flawlessly, and was still working last time I checked... But when turned on, even a light shock can mean goodbye for good.
the best thing is to use an ssd i have 4 hdds in my Alienware 17 r2 i have 1x(512gb m.2) and 2 (256gb m.2) and 1 (4tb hdd for steam. all my personal stuff is on a few 128gb sand disk usb drives. my pics and over important docs are on DVDs nobody uses them but they are the best my be slow at reading but will never fail unless you scratch them
I have taken the lid off of a working hard drive and used it that way. It will work. Probably not very long. But I was able to read files etc. Not recommended for data recovery, but fun to see it work.
After 6 days of scanning hdd wd red 2tb that fell of the table now I hear clicking noise... gonna buy new one to try this. Thank you
Wow. This is very informing. Thanks.
Thank you very much. Learned something from you :D
thanks for this video, man. very helpful.
thank you for nice show
Learning a lot from yours in particular, thank you ^_^
most drives can be forced to read specific tracks with specialized interfaces and software, usually provided thru the manufacturer. this can allow retrieval of partial data from non damaged areas, but only if the heads are undamaged. if heads are non functional, some services have success by actually removing the disc platters and mounting them into a new case with good heads, much like a manufacturing process. inspection at microscope levels to determine suitability is essential before choosing what to do, as even minute surface defects will ruin subsequent heads that attempt access to those areas. most recover is a multistep process, first to enable reliable mechanical operation, then read as much data into an external image file, and finally parse the recovered image file for data structure and useable data.
with many systems, the fragmentation of files is extensive and often very time consuming makingit difficult to recover individual consecutive data (however, even partial data can be useful)
Yes true. Some small percentage of the data is gone, but chances are you can restore most of it in a lab. At least 80%.
how?
@@jerichoular7837 probably only an MRI, very expensive process
@@JerrodJohnsonD lol
Thank you for such an information
Very interesting and detailed. Thank you.
Very educational, thank you.
Great job on the video! You explained this very well thank you!
The Platters make wonderful wind chimes
IKR such a clear silver ring!!!
At least you can get the very strong magnets! I have many of them myself!!!
OMG..Yeahh..
I liked this tear down!!!
after a head crash, I would expect the head(s) to be "junk", so I would not expect them to work, even on undamaged parts of the disk; in the old days, with ferromagnetic coating, one could easily see the "furrow" that was ploughed by the head, and examining the head would also show the magnetic material clogging and/or having scratched up the head(s); good explanation, great video! BTW, I don't think you have to align "bits" on the surfaces, they would automagically align when the disks are reformatted (deep, including timing tracks); a bigger problem IMO would be (re)balancing the disks on the spindle, to avoid "wobble" when they turn at high speed? probably the falling over caused ALL of the "top" heads to "bounce" off the surface, and start pushing up material
thank you for advice and this video
That grinding noise made me make a squished face!
My several LaCie d2 / Quadras have NEVER fallen over!
The base plate foot thing is wider than the drive housing!
Drives always kept in a safe environment!
Since 2007 <

Yep, the MyBooks do tend to get knocked over and this is a great video to describe what happens inside them when this happens.
I much prefer the 2.5" externals anyway.
you have to use a high contrast background to help your camera focus something black and white for instance with crisp edges
I always save the magnets. they are super strong :)
Word?😎
same
Extremely educational
An excellent tutorial of how to destroy a hard disk that still was recoverable.
Yep we are screwed great way to put it man!!
12:34 you need to pull out that stopper (shape like a small black rod between the disk and the yellow stuff) so that the reader can pull out.
The heads look like a great keychain holder once its out.
You are funny! I liked that!😁
you are a legend... thankyou sooo much, i recovered my DATA, oh the excitement, it was all pictures and memories of my children... i'm super super excited, thanks heaps for this video
How could _this_ video help you recover data in any way ? O_o
Informative Thanks
exactly what I needed!
thank you for this work
This vid is so satisfying
Amazing fix THANKS!
Very interesting! Great job.
well nice for you video thank you so much
You should put the screw on the pivot of the moving arm that support the heads.
my drive had this same damage. i sent it to data recovery and are able to recovered most of my data.
Where are recovering your data
I put HD magnets on the bottom of my engine oil filter to catch any metal particles if any are floating around.
thank you for the video
Great video! I wonder those geniuses who disliked this video what found wrong with it.
Cuz they didn't expect to get that much views. Good video
"This is sandpaper..." hahaha nice word to describe it.
Hi Abraham. You sound like RUSSIAN. FOREVER YOUNG. Thanks that you show on the humankind the real.
Good job!
Nice cleanroom
You can't "force" the drive into the read position! Data recovery centres CAN recover data from such drives and it is likely they could have recovered the data off this drive, prior to dismantling.(obviously there will be some data that cannot be recovered where the heads have crashed into the platter). It does depend on the ability to use the original head (or if they can install new r/w heads). Recovery centres have specialised software to step the heads and control which track is read. The data DOES NOT have to align vertically between platters. There is some form of alignment based purely on the relationship between the heads and how they are mounted on the drive, but this has nothing to do with VERTICAL data alignment.
Today's high capacity drives (usually) have logical allocations. This means the drive to the "end user" may be described for example as 2048 tracks and two r/w heads, while in practice, the physical device may have hardware that uses two platters and four heads. The computer requests the drive to write on track 1056, but the hard drive "logically" locates the appropriate track that "represents" track number 1056. This track could be on the second platter, read and written by head three. The computer does not need to know this logical allocation, this is handled by the embedded software on the hard drive.
Praise the lord and all mystic creatures! Not everybody (including the incompetent car mechanics in the video) is out of his mind. Fills me with hope for humanity.
I can not understand why it's not obvious to everybody that 99.9% of the data on the drive was fine BEFORE that """""expert""""" violantly destroyed it while spitting out nonsense about sky being blue, motor rotates and knife doing scratchy noises. DJ Hard Disk in da house.
@@eugenkeller exactly LOL
these noobs who dont know anything about data recovery talk bout head crashes like its the worst thing but guy at ontrack could recover 99% of data so easy even in bad hc cases
I watched a guy do it with scotch taping the drives together as he moved them over to the new drive and he got it to work.
I saw the same vid. The guy made it clear that the platters must stay aligned and that his lab had special equipment to do it. He said the Scotch Tape would not work with many other drives because of clearance problems.
Buff the damage out with a dremel or successively finer grades of wet'n'dry.
+GaryChap lets hope nobody actually believes this xD
No idiot
Halen Martini HE IS KIDDING.
regarding Halen Martini, sarcasm is high level of humour, it has a limited audience, is not for everyone
Onc cannot sense sarcasm without _at leaset_ a *slight* hint that it is sarcasm. The OP did *Not* hint at sarcasm.
Interesting clean room you have and disassembly of the HDD platter. I didn't know you don't have to use gloves...
"you are screwed" - LMAO
8:04 sound like an old telephone ringing. Those turnable dials
the reason its scraping or making that sound when you're turning the disk with it powered off and the head is on the disk, is that when its powered up the air creates a path inbetween the head and the disk which makes it kind of float. kinda like an air hockey table.
I had the same problem with my 1.2TB seagate. I did lose stuff, but you just have to move on. I had two rings like that, one on the outside, and one in the inside.
I just want to make a little correction that HDD is a western digital caviar green.They are used in USB devices and regular PC's i have one of these Hard drives.
Please talk about the tools used so we can do this ourselves.
Hi Abraham,
I just few videos on how to repair laptop's internal hard drives , sounds like you're the best person who can slove my issue.
Can you help me with my laptop issue ?
Thanks.
Maine khub magnet jama kiye hain hdd khol khol ke... Ab bade chotey aatey ...pehle kaphi badey hotey the... Lekin hotey badey powerful hain. Do ko jod dogey toh itni aasani se hilenge nahin. Haan alag karna muskil ho jayega unko. 😀
Good video.
Glue on some felt and you have nice drink coasters!
Thanku very much sir
Thanks for saying the truth
This is why most folks should be getting SSDs, they are not 100% indestructible (You shouldn't be really throwing a SSD like a Frisbee LOL but they could 95% take a drop and still run like a champ.
lol.. "the hard says something is horribly wrong here and ill just turn myself off" I enjoyed this.
At 8:26 he says spinning it "Counter Clockwise" while he is spinning it Clockwise
Nice video
With what you just did to the thing, I'll need to hire a Decepticon to retrieve the data.
The heads were probably destroyed when it scratched the drive. The heads would servo would just search across the media for a reference point - but with no heads, that was impossible. With a replaced head set, you could have possibly gotten some data. If you magnified 80k x you'd still be unable to see the actual head. What you zoomed in on were probably like pre-amps that the heads use to amplify the electron state. NO CHANCE those heads could work once they've hit each other.
You got a lot to learn about hdd. it is very sensitive material doesnt like to be opened.
Not sure if platter replacement is completely impossible, hard drive always uses one head at once and i guess it compensates misalignment and eccentricity a little during rotation. But it's just my guess. I believe tracks are too dense to be able to make hard drive perfect mechanically.
Nice
The hard drive motor can be used as a stationary grinder. Done that several times.
as long as the platter is not terribly tempered with like you did in the video...theres alswyas some data that can be saved
