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!

the disk is now history, and you are the best history teacher ever. Thanks dude.

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!

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.

This is so satisfying, i would watch this before going to bed.

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! :)

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!!"

So the noise coming from my computer is where I thought it was. Thanks for showing us this video.

Thank you for the extensive video. It was indeed informative and fascinating.

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!

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!

very good information. i am a newbie and had no idea why my drive was making that exact noise

Appreciate what you took time to show us.

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.

Yes, but you did not hear one in this video ! :^p

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)

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. :) :)

I really like the way you demonstrate, I subscribed to your channel right away..

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: kzread.info/dash/bejne/fG2ElrealLXKfqQ.html Well, I was mostly right.

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??

Informative video.. Good job.. Keep it up and continue for learners.. Thanks.. Jzakallah..

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

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

An excellent tutorial of how to destroy a hard disk that still was recoverable.

Great video ! I had to open my disc and the good news is that the plate seems to be ok but unfortunately i saw one small piece of the heads, as you have said i do not believe it will be possible to replace the heads to read the plates, but what do i need to do to recover mi data? do I have to remove the plates and put them on another same model drive? is there any other way? thanks in advance.

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.

You should put the screw on the pivot of the moving arm that support the heads.

That grinding noise made me make a squished face!

I put HD magnets on the bottom of my engine oil filter to catch any metal particles if any are floating around.

Thanks for sharing - although I am late to the party. I have a the Western Digital Caviar Green Power 500GB External Hard Disk Drive": It crashed in the year 2525 [ha got carried away in reference to a song] - it actually crashed in 2015! A local shop tech told me that the only way I could recover my data is by obtaining a identical enclosure controller board to read the data? I still have my WD 500GB external hard - I removed the case, but I didn't disassemble the drive itself. I guess I could give it a try again because my toolbox has improved - I own a Thermaltake - BlacX Duet Hard Drive Enclosure Docking Station - Black. any advice?

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.

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.

Very interesting! Great job.

Surely a head replacement would have helped get some data off the disc though? The head had scratched the disc yes so that data is gone obviously. However the head was also visibly damaged so replacing it (assuming the damage isn't on an important part of initialisation) should surely work in recovering some data? Or does any scratch to any part of any disc make it completely unreadable ?

You are funny! I liked that!😁

The hard drive motor can be used as a stationary grinder. Done that several times.

I'm wondering why you did not try to recover any data? I had the exact same HDD shown here. It stopped reading any data. So I opened it the same as you. No visual damage was there, but I did make the mistake of turning it on to see if it spins. It did, and the heads went crazy. I put it back together and was able to recover 90% of the data. Somehow opening it let it work again for enough time to copy/paste data to another drive.

lol.. "the hard says something is horribly wrong here and ill just turn myself off" I enjoyed this.

Hi Abraham. You sound like RUSSIAN. FOREVER YOUNG. Thanks that you show on the humankind the real.

What do you do if the hard drive does nothing at all? No sound whatsoever? It just doesn't work. Thank you for great information!

Enjoyed watching it taken apart but it appeared to me that you could still retrieve a large part of the data that wasn't scratched. Isn't the large unscratched sections still recorded data? Or is the only data on the disc the smaller outer section from where the scratch occured? I'm just curious if there is a way to recover SOME or the undamaged data, and if not, should we hang on to our platters or hard drives incase technology comes up with a way to do so. Thanks for the learning lesson on damage and disassembly.

Way after anyone probably cares given SSDs but the answer is a big "Well..." The fact is there are companies that do computer forensics and have the equipment to do this. It is astronomically expensive and what you get out of it is going to usually be underwhelming. A few things complicate it aside from what is mentioned in the video. Big one is that as this head was swinging back and forth desperately trying to find the FAT or whatever, it was also sandpapering the surface of the disc. While it might look undamaged there are probably unreadable sections scratched all over each track. Some types of files like images may be at least partially recoverable.

You got a lot to learn about hdd. it is very sensitive material doesnt like to be opened.

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.

Mine was clicking, scratching and beeping. Attempted to reset the head placement but it didn't need that as the heads were in place. Looking at the top platter #1 of 3, I see that there are at least 9 scored rings around the top platter going down about 1 inch to the center from outside edge. There are a few metal shavings on the platter too. When I look at the heads. I can see that there is a bent one. Looking at the other heads I one of them looks like a preying mantis at the side waiting for it's prey. It's literally 5 mm off the heads and touching the bottom of the HDD case. Needless to say I'm not very optimistic in getting this fixed!

as long as the platter is not terribly tempered with like you did in the video...theres alswyas some data that can be saved

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.
