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!
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. :) :)
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!
@@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.
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
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
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.
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.
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.
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: th-cam.com/video/J9P4UadRdNA/w-d-xo.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??
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!!"
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!
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 ?
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)
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.
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.
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 Video !. I have a pair of bad HDD and I wonder how to make them spin and also make the actuator moves back and forth, my intention is to put it on a display without the cover without connecting to a computer just power, and then see the disk spin and the actuator moves . thanks
They said the heads don't touch the surface of the disc while spinning because the air friction slightly lift it up but at 5:35 I can hear noise when it reaches the scratch area which means the heads are in contact with the disc while reading data.
1) The cover is off, as the guy said (one of the few smart things he said in this video) it might mess up the air flow which is required for the heads to fly above the platters - at an extremely small distance though. 2) The deep scratches alter the platters' surface, creating irregularities which look small with the naked eye but are enormous compared with the heads' size and the distance at which they normally fly over the platters - just imagine a Formula 1 car driving on a volcanic landscape...
Quick question. My heads look good. the platters have no rings or signs of damage. when I turn it on the heads start to move into the reading position and half way there they stop and pull back and a beep is made. i repeats this about 5 times and then turns its self off. any help? please and thank you!!!
Danielle Becerra he just told you in this video to NOT turn your disk on when the lid is off :/ how do you know they was in that position when it was on? you kind of screwed this one up :(
+Thomas Matikainen That it's a bad idea to turn it on with the lid off doesn't mean that the contents are necessarily destroyed in the process - merely that the risk is greater.
A serious data recovery company will charge an extra fee just to thoroughly and carefully clean the platters in a case like this, when the cover has already been removed in a dusty environment... Attempting a recovery with dusty platters is a recipe for disaster.
I have the same problem... I purchased a 4tb Seagate external drive, I then proceeded to transfer 20 years of data from 4 smaller external hard drives, totalling around 3tb, onto it. I formatted each one as I finished & used them for other things.. About a week later I was vacuuming, caught the external drives power lead under a table, this caused the drive to fall 2" onto its side & it immediately emitted a nasty screaming/grinding/rotating noise, in the same way that one is.. I strongly suspect my platters now look exactly the same as your one.. I will open it at some point to see, I`ve been avoiding it as I`m kinda hoping it will miraculously fix itself, even though I`m 99% sure its now permanently dead. The moral of the story is, always back things up at least twice... I also think I`ll be wrapping my external drives in a couple of layers of bubblewrap in future, just in case..
Indeed that was kinda foolish, to have the opportunity to make a proper backup (having the data on one device only is _not_ a backup), and yet use the older HDDs to hord moar data, probably less worthwhile than those 3TB... You could have recovered part of the older data from those still working drives, depending on how much new data had been written on them since. The damaged HDD could still be partially recovered by a professional data recovery company, if you haven't made a foolish attempt to open it in dusty environment and screw it up for good, but of course it would cost a lotta money, about a whore's day (depending on where you are located it might even be worth ten days of a whore's work, or a kidney).
Nice job guys, do 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??
Not sure I understand why the data would be unrecoverable. The ring would only represent only one track, right? Unless it's track #0 where the directory and allocation data is stored, but even then you would still have recoverable data.
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?
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.
Drives can be stood up. The one in my PS4 has been for a long time because I have the console on a vertical stand. I've been having issues with desktop drive though. When I woke up, my desktop was on and making a loud clicking sound. I wish I could've recorded it but it stopped when I went to record it. The drive's been working weird too, I occasionally will get messages claiming I'm out of storage space on it when there's almost 20 GB left. Even for downloads it said this a couple times
esc1010 lol I just bought one but I haven't transfered windows to it yet. I need to record the sound. It's weird but it almost sounds like normal operation, just louder than normal. It might actually be the hard drive defragging since i had that set up to go automatically which was probably what woke my PC up for no reason. I haven't heard it do it since I got it to stop waking up from sleep on its own
of course they can be stood up, there are many servers which install drives vertically. the problem with getting a standing external drive is that they're usually easy to topple over, and once they topple your data is gonna get fried. even I have a standing external drive, which I keep behind my monitor out of the reach of anyone, though I may end up eventually making it lay on its back just to be safe.
+Hugo Stiglitz that's good, keeping it behind the TV prevents anyone from accidentally toppling it over. now just beware of enemies. ive had a hard drive go like that, a friend was copying stuff to his laptop and he got up without realising that the HDD was connected and my hard drive toppled over and voila 1tb data gone. took it to a recovery center they said they could get 10 data off probably for 1000 dollars.
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
A WD5000AAKS came in a Fantom external harddrive I purchased. Will I be able to get the data off it as a bare drive connected to a USB to SATA adaptor without the electronics of Fantom enclosure?
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 < J.C.
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!
My hard drive sort of clicks and doesn't recognize, so I opened it up and the platter looks super clean and fine. However, the end of the thing (IDK the name, I think you call them disks) that goes over the platter is cracked at the head. I assume this is very very bad and that means it's over.. The head of the "disk" the very pointy part on the end, is like cracked and almost bent.
What are these dents seen at 0:25 on the side of the HDD caused from? I just received a HDD that has these dents and am not sure if I should return it.
I also have a wd 1tb that felt( 50 60 cm ) and works but it was in box and buble rap allso hit lateral as i was trying to stop it whith my leg from hiting the flor side into a foset filed bag
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.
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
Even if you get the identical parts with all the matching specs ... you still can't replace the head since new drives are all pre-calibrated at the factory with specific settings in the firmware... & it's different for each and every single drive.
Hugo Trujillo I read an article about it... was a while ago so I can't link it. Anyway, the method used to work with older drives.. but now new drives that have like 1 tb on a single platter are many times more dense & the calibration needed is equally more precise.. so even the smallest misalignment will throw the head off... & each drive has differences at this level of precision.. hence requiring a different calibration.
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.
@@tee2567man you’re completely delusional, after a head crash you can easily recover the data, you only wont be able to recover the data on the small portion of the platter where the head smashed, guys at ontrack do that on a daily basis
Two identical Seagate 2.5-inch SATA2 HDs (kept in reserve storage for about five years) now demonstrate the same noise-- a faint, two-per-second beep, but no click. Almost as though the motor is switched on, encounters stiction, and is immediately switched off to avoid motor damage. Immediately afterward, the startup cycle repeats. There is no discernible break between cycles, only continuous two-per-second beeping. Presuming stiction is the problem, here are two questions. (1) Since opening the drives (with no data on them) is a death-sentence, do you know of any other way to dislodge heads attached to the platter surface by "stiction"? Since there is no data of value involved, I am willing to do anything short of causing a head crash, gouging the platter recording surface. (2) The modern HD head is supposed to park itself automatically on power--down. One of these virgin drives was briefly tested on delivery, and then shut down in an orderly fashion, with no bumping or motion for at least 15 seconds. Under such circumstances, the head should have parked itself, and not have been in contact with the platter surface, at all. The other drive was never unpacked, but its should have been issued by the factory with its head in parked position, as well. So, how could stiction have occurred?
If "stiction" is the issue and these drives are of the type that park their heads on a special zone of the platters designed for landing (vs offload drive types), then in theory, you can dislodge them using external force. You will need to identify which direction the head stack assembly swings and where in the drive the heads land. Most likely it parks near the center of the platter (small radius). You can then, with the drive powered down, apply a small force in the direction that will cause the head stack to over center. By contrast, you do not want to apply a force in the opposite direction as that will cause the heads to rotate out into the data area. Given the assumptions I have made, if the right force is applied in the right direction, the heads will be jarred loose allowing the drive to spinup next time it is powered up. Keep in mind, this is very risky, but theoretically possible.
I have an external drive on a mac that's not reading the files, you can hear the disc spinning, it also says drive has ejected on the screen, although i hadn't disconnected it , i really want to save whats on the drive

Hello Abraham,I had my external hard drive peeping. I opened it after watching your videos and took the head away from the platter. I closed it and tried it, but still peeps 4 or 5 times and it does not start or make any sound. Then it goes quite. It does not show on my computer and there is a message that comes out not recognized. Could you help me please?
nice video, i have a question, to start i am not new and computers and setting up systems, the new system i set up has 1 4tb, 1 6tb, (1 8tb 3 10tb,helium filled ) i get a sound from one don't know which one it sound is like ( b...b...b...b ..b) like the drives head is moving, but no disk activity as for moving files, all drives smart look good not bug or faults, only as the case is on the desk i hear this or i would never as in the bast the case is on the floor. would this be a normal sound and is there a web page i can go to that have a list of hard drive sounds.
How do you know by the sound that the head is not stuck on the plate? Or a spindle won't spin? How do you decide to replace the panel..... The noise sounds the same to me :-/

What is the average cost of data recovery? Also, what is the best place, with the best price, to fix my WD external 500GB drive? My drive was dropped. It clicks, like it wants to run, but it won't. Please advise.
My Freecom 500gb only dropped from foot high onto soft carpet and is broken. I took it apart and there are few light ring scratches on the disk. I took look at the head and is wire like old gramophone player needle that is causing the scratches. Looks like no hope right now of ever recovering data.
Hi...What if my portable hard disk makes continuous clicking noise while it still can flash up my folders unfortunately cannot read or open any files at all.

By the way my hard disk became faulty because of premature removal from USB. Hope you can help.
I wonder if someone could give me some advice, bought a new 2tb hard drive fitted it a year ago, used it as a storage dump for media. A few days ago, it made some really loud grinding sounds. Later when I checked my drives, the E drive was gone on windows, but I could see it in disk management. The 2tb volume of the drive then read as 3.68 GB, when trying to fix the problem, it came up as ‘i/o device error’. Tried CMD to see if I could work the problem and got ‘Cannot Open Volume for Direct Access’ on that. The drive was only half full which surprised me re volume, nothing I have tried worked. When I use device manager, it says the drive is working properly when it patently isn’t. Would this suggest that the drive is dead? Any help would be appreciated.

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.

@@trulygrateful7217 Ah! :(
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: th-cam.com/video/J9P4UadRdNA/w-d-xo.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??
Excellent video of what to do, and what NOT to do if attempting this type of repair.
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
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.
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!
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 ?
Thank you for the extensive video. It was indeed informative and fascinating.
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)
Appreciate what you took time to show us.
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
It's always interesting to know the expert's opinion.
Yes, but you did not hear one in this video ! :^p
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.
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.
very good information. i am a newbie and had no idea why my drive was making that exact noise
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.
what if you turn the disk upside down and reassembly it, could it read the data?
Thanks for this vid. Gives me a better understanding of harddisks.
An excellent tutorial of how to destroy a hard disk that still was recoverable.
The best explanation for this process I have seen so far!👍👍
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 Video !. I have a pair of bad HDD and I wonder how to make them spin and also make the actuator moves back and forth, my intention is to put it on a display without the cover without connecting to a computer just power, and then see the disk spin and the actuator moves . thanks
They said the heads don't touch the surface of the disc while spinning because the air friction slightly lift it up but at 5:35 I can hear noise when it reaches the scratch area which means the heads are in contact with the disc while reading data.
1) The cover is off, as the guy said (one of the few smart things he said in this video) it might mess up the air flow which is required for the heads to fly above the platters - at an extremely small distance though.
2) The deep scratches alter the platters' surface, creating irregularities which look small with the naked eye but are enormous compared with the heads' size and the distance at which they normally fly over the platters - just imagine a Formula 1 car driving on a volcanic landscape...
Quick question. My heads look good. the platters have no rings or signs of damage. when I turn it on the heads start to move into the reading position and half way there they stop and pull back and a beep is made. i repeats this about 5 times and then turns its self off. any help? please and thank you!!!
Danielle Becerra he just told you in this video to NOT turn your disk on when the lid is off :/ how do you know they was in that position when it was on? you kind of screwed this one up :(
+Danielle Becerra may be the control, board
+Thomas Matikainen That it's a bad idea to turn it on with the lid off doesn't mean that the contents are necessarily destroyed in the process - merely that the risk is greater.
A serious data recovery company will charge an extra fee just to thoroughly and carefully clean the platters in a case like this, when the cover has already been removed in a dusty environment... Attempting a recovery with dusty platters is a recipe for disaster.
I have the same problem... I purchased a 4tb Seagate external drive, I then proceeded to transfer 20 years of data from 4 smaller external hard drives, totalling around 3tb, onto it. I formatted each one as I finished & used them for other things.. About a week later I was vacuuming, caught the external drives power lead under a table, this caused the drive to fall 2" onto its side & it immediately emitted a nasty screaming/grinding/rotating noise, in the same way that one is..
I strongly suspect my platters now look exactly the same as your one.. I will open it at some point to see, I`ve been avoiding it as I`m kinda hoping it will miraculously fix itself, even though I`m 99% sure its now permanently dead.
The moral of the story is, always back things up at least twice...
I also think I`ll be wrapping my external drives in a couple of layers of bubblewrap in future, just in case..
Indeed that was kinda foolish, to have the opportunity to make a proper backup (having the data on one device only is _not_ a backup), and yet use the older HDDs to hord moar data, probably less worthwhile than those 3TB... You could have recovered part of the older data from those still working drives, depending on how much new data had been written on them since. The damaged HDD could still be partially recovered by a professional data recovery company, if you haven't made a foolish attempt to open it in dusty environment and screw it up for good, but of course it would cost a lotta money, about a whore's day (depending on where you are located it might even be worth ten days of a whore's work, or a kidney).
Informative video..
Good job..
Keep it up and continue for learners..
Thanks..

What if I accidentally scratched the disk with the star screwdriver?
what have i to do if my hard drive is clicking and when it clicks the Pc didn't finds it?.... please help me my hard drive is a toshiba 720gb
Nice job guys, do 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??
Kya aap damage platter s data recovery kar sakte hai???
Not sure I understand why the data would be unrecoverable. The ring would only represent only one track, right? Unless it's track #0 where the directory and allocation data is stored, but even then you would still have recoverable data.
At least you can get the very strong magnets! I have many of them myself!!!
OMG..Yeahh..
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?
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.
Drives can be stood up. The one in my PS4 has been for a long time because I have the console on a vertical stand.
I've been having issues with desktop drive though. When I woke up, my desktop was on and making a loud clicking sound. I wish I could've recorded it but it stopped when I went to record it. The drive's been working weird too, I occasionally will get messages claiming I'm out of storage space on it when there's almost 20 GB left. Even for downloads it said this a couple times
"loud clicking sound"
back your shit up and buy a new drive asap
esc1010 lol I just bought one but I haven't transfered windows to it yet.
I need to record the sound. It's weird but it almost sounds like normal operation, just louder than normal. It might actually be the hard drive defragging since i had that set up to go automatically which was probably what woke my PC up for no reason.
I haven't heard it do it since I got it to stop waking up from sleep on its own
of course they can be stood up, there are many servers which install drives vertically. the problem with getting a standing external drive is that they're usually easy to topple over, and once they topple your data is gonna get fried. even I have a standing external drive, which I keep behind my monitor out of the reach of anyone, though I may end up eventually making it lay on its back just to be safe.
Dhruv1223 I also have an external standing vertically behind a TV. Cable doesn't quite reach the input so I stood it up to get some extra slack
+Hugo Stiglitz that's good, keeping it behind the TV prevents anyone from accidentally toppling it over. now just beware of enemies. ive had a hard drive go like that, a friend was copying stuff to his laptop and he got up without realising that the HDD was connected and my hard drive toppled over and voila 1tb data gone. took it to a recovery center they said they could get 10 data off probably for 1000 dollars.
2:20 3:10 3:32 4:00 8:44 10:40 11:45 12:05 12:44 I added the timestamps
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
A WD5000AAKS came in a Fantom external harddrive I purchased. Will I be able to get the data off it as a bare drive connected to a USB to SATA adaptor without the electronics of Fantom enclosure?
my drive had this same damage. i sent it to data recovery and are able to recovered most of my data.

Hi.
My needle/head goes back and forth and it looks like the disc doesn't spin at full speed. I can't read the harddrive on my PC. Any ideas? Regards
Maybe swap controller board (pcb) with one from donor drive of same manufacture and factory.
How about replacing the head instead of trying to swap the platters?
Is it possible to install the disc in another driver, JUST the disc
Yes but U have to be very careful
Oh okay, I'll keep that in mind and yeah thanks
Noticed the head and players, question would it be possible to replace ( the same) players upside down as it appears only one side damaged??????
It's gonna damage the other side as well... lol
Buff the damage out with a dremel or successively finer grades of wet'n'dry.

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.
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!
My hard drive sort of clicks and doesn't recognize, so I opened it up and the platter looks super clean and fine. However, the end of the thing (IDK the name, I think you call them disks) that goes over the platter is cracked at the head. I assume this is very very bad and that means it's over.. The head of the "disk" the very pointy part on the end, is like cracked and almost bent.
What are these dents seen at 0:25 on the side of the HDD caused from? I just received a HDD that has these dents and am not sure if I should return it.
I also have a wd 1tb that felt( 50 60 cm ) and works but it was in box and buble rap allso hit lateral as i was trying to stop it whith my leg from hiting the flor side into a foset filed bag
I always save the magnets. they are super strong :)
Word?😎
same
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.
My drive looks very similar to this except the circle is toward the center. Is my data completely lost?
Question: if you put one of those disks in a dvd player, could it read it?
Yeah
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
Even if you get the identical parts with all the matching specs ... you still can't replace the head since new drives are all pre-calibrated at the factory with specific settings in the firmware... & it's different for each and every single drive.
+Advection357 who told you that?
Hugo Trujillo I read an article about it... was a while ago so I can't link it. Anyway, the method used to work with older drives.. but now new drives that have like 1 tb on a single platter are many times more dense & the calibration needed is equally more precise.. so even the smallest misalignment will throw the head off... & each drive has differences at this level of precision.. hence requiring a different calibration.
Please talk about the tools used so we can do this ourselves.
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.
@@tee2567man you’re completely delusional, after a head crash you can easily recover the data, you only wont be able to recover the data on the small portion of the platter where the head smashed, guys at ontrack do that on a daily basis
What size screws are those?. I have a clicking external seagate I want to take a look at.
What kind of screw driver do you use? How is it called?
Two identical Seagate 2.5-inch SATA2 HDs (kept in reserve storage for about five years) now demonstrate the same noise-- a faint, two-per-second beep, but no click. Almost as though the motor is switched on, encounters stiction, and is immediately switched off to avoid motor damage. Immediately afterward, the startup cycle repeats. There is no discernible break between cycles, only continuous two-per-second beeping.
Presuming stiction is the problem, here are two questions.
(1) Since opening the drives (with no data on them) is a death-sentence, do you know of any other way to dislodge heads attached to the platter surface by "stiction"? Since there is no data of value involved, I am willing to do anything short of causing a head crash, gouging the platter recording surface.
(2) The modern HD head is supposed to park itself automatically on power--down. One of these virgin drives was briefly tested on delivery, and then shut down in an orderly fashion, with no bumping or motion for at least 15 seconds. Under such circumstances, the head should have parked itself, and not have been in contact with the platter surface, at all. The other drive was never unpacked, but its should have been issued by the factory with its head in parked position, as well. So, how could stiction have occurred?
If "stiction" is the issue and these drives are of the type that park their heads on a special zone of the platters designed for landing (vs offload drive types), then in theory, you can dislodge them using external force. You will need to identify which direction the head stack assembly swings and where in the drive the heads land. Most likely it parks near the center of the platter (small radius). You can then, with the drive powered down, apply a small force in the direction that will cause the head stack to over center. By contrast, you do not want to apply a force in the opposite direction as that will cause the heads to rotate out into the data area. Given the assumptions I have made, if the right force is applied in the right direction, the heads will be jarred loose allowing the drive to spinup next time it is powered up. Keep in mind, this is very risky, but theoretically possible.
what are you using to take out that center at 11 mins , it looks like your turning it clockwise to undo the screws,, I can not undo mine.
I have an external drive on a mac that's not reading the files, you can hear the disc spinning, it also says drive has ejected on the screen, although i hadn't disconnected it , i really want to save whats on the drive
Can't you just replace the read/write heads? What about the data beyond the scratched area? Is that data not retrievable?
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
Hello Abraham,I had my external hard drive peeping. I opened it after watching your videos and took the head away from the platter. I closed it and tried it, but still peeps 4 or 5 times and it does not start or make any sound. Then it goes quite. It does not show on my computer and there is a message that comes out not recognized. Could you help me please?
nice video, i have a question, to start i am not new and computers and setting up systems,
the new system i set up has 1 4tb, 1 6tb, (1 8tb 3 10tb,helium filled ) i get a sound from one don't know which one it sound is like ( b...b...b...b ..b) like the drives head is moving, but no disk activity as for moving files, all drives smart look good not bug or faults, only as the case is on the desk i hear this or i would never as in the bast the case is on the floor. would this be a normal sound and is there a web page i can go to that have a list of hard drive sounds.
Still possible retrieve data from this damaged surface if it really necessary.
can a bad head cause the hard drive not to power up with a transfer power supply cable?
What about replacing the drive motor? Mine just doesn't spin anymore.
You should put the screw on the pivot of the moving arm that support the heads.
What’s the name of the screw driver you are using please ? I have the same issue 😢😩
can you put oil in the bearings of the disk so it wont get stuck again?
How do you know by the sound that the head is not stuck on the plate? Or a spindle won't spin? How do you decide to replace the panel..... The noise sounds the same to me :-/
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.
isn't there any way of replacing platters or heads?
What is the average cost of data recovery? Also, what is the best place, with the best price, to fix my WD external 500GB drive? My drive was dropped. It clicks, like it wants to run, but it won't. Please advise.
Did this give you the dreaded In/out error, no bootable device found?
So if this would have fallen over while it WASN'T running, that'd have been less likely to cause issues, correct?
That little arm isn't going to the center and reading it, any help on that?
My Freecom 500gb only dropped from foot high onto soft carpet and is broken. I took it apart and there are few light ring scratches on the disk. I took look at the head and is wire like old gramophone player needle that is causing the scratches. Looks like no hope right now of ever recovering data.
what size torx was used to remove the platter ring at 10:37 on...i can seem to find on in my kit that fits?( same WD 500 gig drive it appears)
I put HD magnets on the bottom of my engine oil filter to catch any metal particles if any are floating around.
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!
My harddisk does the same thing at 5:35, can it be fixed?
So there is now way you can recover the data from those platter disks ? or is there a way ?

Hi...What if my portable hard disk makes continuous clicking noise while it still can flash up my folders unfortunately cannot read or open any files at all. Should I attempt your stunt to manually park the head which I think I should keep this attempt to the last when all else fails to help. By the way my hard disk became faulty because of premature removal from USB. Hope you can help.
I wonder if someone could give me some advice, bought a new 2tb hard drive fitted it a year ago, used it as a storage dump for media. A few days ago, it made some really loud grinding sounds. Later when I checked my drives, the E drive was gone on windows, but I could see it in disk management. The 2tb volume of the drive then read as 3.68 GB, when trying to fix the problem, it came up as ‘i/o device error’. Tried CMD to see if I could work the problem and got ‘Cannot Open Volume for Direct Access’ on that. The drive was only half full which surprised me re volume, nothing I have tried worked. When I use device manager, it says the drive is working properly when it patently isn’t. Would this suggest that the drive is dead? Any help would be appreciated.
Not true. Some small percentage of the data is gone, but chances are you can restore most of it in a lab. At least 80%.
Exactly, and he is just destroying customer data. If you cant repair, why screw it more? hand it to someone more experienced.
