Screwdriver for disassembling a hard drive. How to remove a screw from a hard drive? Option No1. Phillips slot
1. Assign a drive letter, the system will not see a drive without a letter.
2. A program like Acronis will help you.
3. You can find the boot partition magic, and use it to work with partitions.
It’s easier to “password” user accounts of the operating system (but keep in mind that in Windows OS you can simply “reset” it). And a password for the entire disk can be set using special. software for data encryption (DriveCrypt, for example).
I don’t know what it is, but go to the root of this disk with a “third-party file manager” that shows hidden and system files, Far for example, and delete everything there, or at least look at what files are there. and best of all, copy everything you need from there and format it.
Mmmmmm, let me see...
I have 80 (at work) and it’s calling
and at home the note is from 60, that’s also enough
PySy And it’s not good to brag. Didn't your mom teach you? :)
What do jumpers have to do with it if the disk doesn’t even “buzz”? That is, the plates do not spin. And this cannot be cured with jumpers.
Or the disk is completely dead. Or, if you’re sooooo lucky, the power protection worked. And this can be cured in the workshop.

Until it is possible... when formatting, you select which of the disks you want to Format...
If you look on the Internet, there are a lot of programs that can solve this problem. Most of them are paid (shareware in native language), but this does not mean that even a paid program will not harm the performance of your unit. It is highly not recommended to use programs of this type, they do not provide any guarantee, especially those that will install protection at the level of the boot sector of the hard drive - you will also lose the primary one (supposedly)...
If your hard drive fails, you can take it apart for parts. But such a procedure requires certain skills. To properly disassemble a hard drive, it is important to know a few useful rules.
If you want to repair your hard drive, then know that you cannot open it at home. During assembly of the hard drive, a vacuum is specially created inside the box, thanks to which the device can operate for a long time. If you pull out a hard drive, it will become unusable after a few seconds of exposure to air. Therefore, you can disassemble the device only if you are completely sure that it is faulty. Before removing the hard drive, turn off the computer and unplug the wire from the outlet. If you are using a desktop computer, remove the side panels from the system unit. There are six bolts on the back of the cover. Unscrew them to remove the hard drive without unnecessary obstacles. Disconnect all wires and cables that are connected to the hard drive. Do this very carefully so as not to damage the wires. After this, you can begin to unscrew the hard drive mounting bolts. If you want to remove the hard drive that is in the laptop, first completely disconnect it from the power supply, close the lid and turn it over. Remove the battery from the computer. There is a special latch on the laptop body. Grab it with one hand, and with the other, press up on the back of the computer. Proceed carefully - to ensure that nothing breaks, apply even force. Then the cover will give way and you can remove it from the body.
Now you know how to disassemble a hard drive into small parts. Try to act slowly and carefully - then you will not damage anything and remove the necessary elements safe and sound.
External hard drives from any manufacturer, including Western Digital, are convenient due to their mobility. If you purchased the hard drive and the case for it separately, then you should not have any questions during assembly and disassembly. However, in the case of “ready-made” external hard drives from the manufacturer, the case often lacks the necessary bolts and fasteners, therefore, the case cannot be disassembled.
You will need
- - screwdriver.
Instructions
Carefully inspect the hard case disk. Remove protective rubber bands, if any. Prepare a couple of plastic cards (that are not afraid to break) and a flat-head screwdriver. As a rule, hard drive models may differ slightly in assembly, so prepare a couple of screwdrivers of different diameters.
Carefully insert the corner of the plastic card into the slot on the case. Move the card slightly until the entire edge of the card fits into the slot. Now press lightly on the card to widen the gap. Repeat this procedure for the other side of the case. If necessary, insert two cards at the same time to loosen the fastening on opposite sides.
Expand the gap until you hear a slight click - at this moment the internal latches hidden in the case will open. Unlock the latches on all sides. Now you can remove the plastic cards. Try to perform these procedures carefully, as you can damage the entire body, as well as the insides.
Open the housing using a screwdriver. Remove the hard drive after disconnecting the fan (if equipped) and the controller connectors. If you didn't break the latches, then the hard drive can be easily put back together.
Proceed with caution as any sign of damage to the external hard case disk, even a small scratch will constitute mechanical damage and you will void the warranty on the device. You should not disassemble the external hard drive unless absolutely necessary. As practice shows, most disassembled hard drives do not work when reassembled, because various dust gets inside, or the bolts are simply not tightened correctly. Try to use unnecessary parts for disassembly.
Having dared to repair a hard disk, many novice users do not understand what they can do with the disk if they open it at home. When assembling a hard disk During production, a vacuum is created inside the box, which allows it to work for a long time. The hard drive becomes unusable after a few seconds of exposure to air. Experienced personal computer users disassemble the hard drive case disk only with full confidence in the non-working state of the hard disk.
You will need
- Hard drive, screwdriver “+”, hexagon.
Instructions
Hard disassembly disk start by dismantling the control board. The control board is a regular circuit board onto which a set of parts is soldered, including modern memory chips. Depending on the type of hard disk, for dismantling you will need either a screwdriver or a hexagon. Remove the 3 main screws, then remove the hard drive control board. disk.
Under the control board there is a hard drive cover disk, under which the entire hard drive device is located disk, which you've probably seen many times in photos taken by other users of broken hard drives. Remove the 7 screws, then remove the hard drive cover disk. The main task of dismantling the hard disk finished. If you are disassembling a hard drive for the parts that are inside, then proceed further.
All other parts: filter, heads and disks can be disassembled with a screwdriver. Be careful when disassembling the rigid head mechanism disk– they are equipped with powerful magnets, you can get your finger pinched. After you remove the “pancakes” of the hard disk, you can make sure that their surface is easily scratched by any object. The number of heads in a hard drive is twice as large as the number of “pancakes”. Therefore, if your hard drive had 4 “pancakes”, therefore, the number of heads will be equal to 8.
When some hardware problems appear with a hard drive, if you have the proper experience, it makes sense to inspect the device yourself, without resorting to the help of specialists. Also, those people who just want to gain knowledge related to assembly and the general view from the inside resort to disassembling disks on their own. Typically, non-working or unnecessary HDDs are used for this purpose.
First, I would like to warn beginners who want to try to fix the hard drive themselves if any problems arise, for example, a knock under the cover. Incorrect and careless actions can easily damage the drive and lead to permanent damage and loss of all data stored on it. Therefore, you should not take risks, wanting to save money on the services of professionals. If possible, make backup copies of all important information.
Do not allow debris to get on the hard drive plate. Even a small speck of dust is larger than the flight height of the disk head. Dust, hair, fingerprints or other obstacles to the movement of the read head on the plate can damage the device, and your data will be lost beyond recovery. Perform the analysis in a clean and sterile environment, wearing special gloves.
A standard hard drive from a computer or laptop looks like this:
The back is usually the back of the controller that is held on by torx screws. These same screws are also on the front of the case. In some cases, an additional screw may be hidden under the factory sticker, so after unscrewing the visible screws, open the cover very smoothly, without sudden movements.
Under the cover there will be those components of the hard drive that are responsible for writing and reading data: the head and the disk platters themselves.
Depending on the volume of the device and its price category, there may be several disks and heads: from one to four. Each such plate is put on the motor spindle, arranged according to the “storey” principle and separated from the other plate by a sleeve and a bulkhead. There can be twice as many heads as disks because each platter has both sides for writing and reading.
The disks rotate due to the operation of the motor, which is controlled by the controller through a loop. The principle of operation of the head is simple: it rotates along the disk without touching it and reads the magnetized areas. Accordingly, all interaction of these parts of the disk is based on the principle of an electromagnet.
The head has a coil on the back where the current flows. This coil is located in the middle of two permanent magnets. The strength of the electric current affects the strength of the electromagnetic field, as a result of which the bar chooses one or another angle of inclination. This design depends on a separate controller.
The controller contains the following elements:
In this article we told you how to disassemble a hard drive and what parts it consists of. This information will help you understand the principle of operation of the HDD, as well as possible problems that arise during operation of the device. We remind you once again that the information is for informational purposes only and shows how to disassemble an unusable drive. If your disk is functioning normally, then you cannot disassemble it yourself - there is a high risk of damaging it.
This photo report will be a good addition. Firstly, the article did not include all the photographs, but here is the complete set with a description. Secondly, when preparing this report, and especially when compiling descriptions of the photographs, I remembered many points and details that were not in the article. These details relate directly to the design of the hard drive and will be of interest to those who are interested in disassembling the hard drive or repairing hard drives.
Original “hard”, front side (top) 
The hard drive is assembled with star screws; you need a special screwdriver with a star cross-section, in this case hexagonal. 
Our test subject has the most popular interface for connecting hard drives - SATA (although for our experiments this does not matter). 
A hard drive after it was in the hands of a small child. Result: the motor power cable is broken, mechanical damage to the board. Result: the hard drive is 100% damaged. 
As it turned out, under the factory sticker the manufacturer placed additional fasteners - another star screw (it took me a long time to figure out why the cover could not be removed). 
Finally the cover is off! Indescribable beauty. It looks like some kind of ultra-modern record player. Everything glitters and sparkles. It’s even a pity to pick further (the author’s face is reflected in the reflection). 
I took pictures from different angles so that everything could be seen in detail. By the way, I forgot to say in the article, but now I saw: on the lower left side of the case there is a special pocket where a bag of silica gel is placed to maintain the humidity level inside the hard drive case. 
Another general plan for clarity. 
A rod with writing (reading) heads. The rod is mounted on a bushing. Its tail is hidden under a powerful permanent magnet. Below is another similar magnet. Thus, the “tail” of the rod is in the magnetic field of two permanent magnets. 
Here it is - the upper permanent magnet. An ordinary metal plate, but very highly magnetized. By the way, I have already thought of a use for it. When you disassemble equipment that has small screws (laptop, tablet), it is convenient to use such a magnet to pull them out of the channel after unscrewing them (for this, the tip of a screwdriver is usually magnetized, but it happens that it is not magnetized). Perhaps sometime later I’ll write an article on “how to magnetize a screwdriver.” 
The tail of the rod is a coil to which electric current is supplied, that is, an electromagnet. When the fields of the electromagnetic coil and permanent magnets interact, the rod begins to move. Depending on the voltage and intensity of its supply (frequency), the rod deflects at different speeds to a certain angle. 
Contact plate connecting the rod with the heads and the controller on the main board. A rather complex device, since one loop completely controls the movement of the rod, transfers data from disks to memory (when reading), from memory to heads (when writing), as well as other control commands (for example, erasing information or transferring its individual parts ). If you also take into account that there are as many as four write (read) heads... in general, a complex data transmission and control system. 
This photo shows that one of the disks has been removed from the spindle. Below it is another disk. Each of the disks is separated from the other by a metal ring, as well as an aluminum bulkhead, which is correctly called a “separator”. A separator (separator) is a rather interesting engineering solution designed to distribute and balance the air flows that occur when the disks rotate. 
One of the disks removed from the hard drive and fastening from the spindle (fitted tightly over the disks and tightened with screws on six sides). 
Aluminum separator. The discs inside rotate at a huge speed of several thousand revolutions per minute, depending on the model and manufacturer. In this case, strong air currents arise that prevent the write/read heads from touching the disks (the reading/writing process occurs at a distance of several nm). The separator is designed to balance air flows to improve aerodynamics. The design of the heads and separator is specifically designed to take these air flows into account. 
Hard drive with disks removed from the spindle. 
The cable that powers and controls the hard drive motor has been mercilessly torn out. From this we can conclude that this hard drive can no longer be restored. 
A rod with heads and a cable with a contact plate removed from the axis. 
Barbell in profile. You can clearly see that it has four heads at the end. One of the control controllers is located directly on the boom. 
The control unit board is the brain of the hard drive. Here are all the mechanical control controllers, a microprocessor, a memory cache, a ROM chip with all the device parameters stitched into it, starting from the manufacturer, batch number, date and ending with technical parameters... 
Two permanent magnets, between which the “tail” of the rod with heads moves. I don’t know why I took a photo, just for the sake of it.
