All information that exists today can be stored on special devices called a hard drive or hard drive. Their choice is great, and the capacity allows you to store thousands of photos, films, games, documents and other files necessary for the user. However, like any complex device, the hard drive may fail, which will require troubleshooting and subsequent corrections.
Only complications of faulty equipment will be resolved. If you don’t know which part of the laptop: what the laptop does. If you do not know how to disassemble a laptop, use the instructions: How to break a laptop. But how to determine what is wrong? If the error stops displaying, we just discovered the component that caused this problem. For example, a new RAM located in one older laptop will work reliably, but the same RAM in the second laptop will not disappear, although the manufacturer says that it is compatible.
Repair external hard drives
External drives have gained popularity due to their compactness - a person can carry a huge amount of information with him. Such devices are reliable, but they are not insured against breakdowns. If the failure is not associated with mechanical damage, then you can repair the external hard drive yourself.
Just different combinations of hardware can lead to a different result. Therefore, if the memory is not functioning properly, when it does not work on the same laptop, it will be wrong. In another combination of components, it can work reliably.
Most quick search missing components that are often only visible occasionally. After making changes to the laptop assembly we need long time watch the laptop so we can take a hit. If you do not have other functional components for testing, ask someone in your circle of knowledge, for example, to give you a try on your laptop for testing.
Repairing a hard drive after a fall or other physical influences is difficult to carry out at home.
- Opening of the block of magnetic heads will be required, which can only be carried out in a clean, sterile room. Any dust is harmful to the magnetic inside of the device.
- Repair after mechanical damage requires specific knowledge and tools to find a broken element and replace it. The most rational solution is to contact a service center.
A bit easier to handle software crashes , which, according to statistics, bother users of external hard drives even more often than defects obtained from physical influences. Frequent cases affect incorrect completion work.
It is clear that it will be much more difficult to find other functional components for testing than, for example, in computer assemblies, because, unfortunately, for laptops, unfortunately, there are many different standards. We can easily capture only hDD, RAM and power adapter, as there are only a few basic standards for these components.
It is also possible to use diagnostic tools and check the status of a component using these devices. This is no longer an effective solution, but if we do not have other components for testing, these diagnostic tools can help us identify the defective component.
We begin the diagnosis and repair by checking the health of the USB cable, which connects the drive to a PC, TV, etc. You can connect the cable to another device and see if it is working.
If a laptop or PC determines the connected external hard drive, but working with it is accompanied by freezes, crashes, errors, then it’s nice to check it for viruses, some of which are quite capable of disrupting the hard drive.
If the laptop cannot repair the laptop, the last possible solution becomes clear: we will take it away or send it to the computer service that is provided for these repairs. If it's an old laptop, sometimes it's better to buy a new one. A hard drive is not hardware that boasts great resistance to potential drops and bumps.
What if a fall and subsequent damage occurs? A mechanical hard drive inside hides a bunch of moving parts that can easily be torn or damaged if dropped or shaken. This is mainly due to the fact that they are not hidden inside the computer case, so users often fall during switching and transmission.
The next step - formatting. Be sure to spend a full, not fast. There are a lot of programs for this procedure: Acronis Disk Director, HDD Low Level Format, etc.
Formatting can be started through command line, "Disk Management" or "My Computer".
A fall can cause mechanical damage to the recording layer on which the data is stored, except that it does not break the read head and does not damage the rotating motor. If the drive behaves differently after a failure, or if it does not work completely, seek technical assistance.
This error will suddenly appear, and the disk will begin to click on it regularly. Without expert diagnosis in the laboratory, it is almost impossible to distinguish from a case of surface damage. A defect can only occur on one of all heads. Data recovery involves the use of a functional bunch of heads, but due to the possibility of surface damage, careful analysis is required. Recovery itself is 100% successful. There is no special protection against this failure, it is a typical failure predictable with a certain probability.
The main thing is to choose in the settings file system NTFS.
If the computer sees an external hard drive, but it is impossible to extract information from it, then it is good to determine which part of it is badly damaged and which files can be extracted and restored. Programs are suitable for this. Recuva, Partition recovery other. By launching one of them, you will see a list of files that can be returned, and “beaten” information can simply be deleted by returning the hard drive to its previous working capacity.
Freeze Damage
For hard drives The most risky moment is the beginning or landing of headings. The second most common defect is damage to stopping the parking position of the heads when all heads are pulled out of the shoulder. The disc starts to click, and the rest of the hinges and loose heads can damage the surface. Data recovery is successful in the described cases, but technically very demanding.
This cannot be done without special tools. There is no special protection, except compliance with the prescribed operating temperature and intervention at the first difficulty - the longer time required to start the drive. Make sure you do not turn on the drive and / or the entire computer after detecting and displaying symptoms so as not to cause more damage.
Do-it-yourself laptop hard drive repair
First of all, pay attention to extraneous sounds in the hard drive when you turn on the laptop. It can be clicks, tapping, accompanied by a slowdown and freezing. There are many reasons: from the banal ingress of dirt and dust to damage to the drive, jamming or misalignment of the spindle.
Data Recovery - Order Form
If signs of damage are found, write them down as best as possible and contact professionals who will be happy to advise and recommend what to do next. On the page. Their professionalism is highly valued in our country. You made us very happy! For me it was very nice, the data was very important for me. Thank you, you have all the golden hands. Thank you for returning my hard drive.
- Today we have saved external drive.
- We would like to thank the experts who completed this work.
If the laptop stops seeing the hard drive, then you can try to determine the cause of the malfunction and fix it yourself. To do this, there is an instruction, given which it is necessary to sequentially perform each item:
- Remove the hard drive from the laptop case.
- Next, unscrew the controller board - you need a screwdriver "sprocket". Remember that thereby you lose the guarantee. In some HDD models, the elements are located on the outside and can be seen without further action.
- Carefully inspect the board for damage. Often due to overheating on the microcircuits, swelling or carbon deposits are formed. You can also use a magnifying glass and examine the places of soldering connectors: even one fallen off leg can seriously disrupt the operation of the entire device. If you find such signs, then you can calm down - the repair will not be delayed. It is enough to find the article or name of the board on the Internet that is suitable for your hard disk. Then purchase it and replace it.
- Do not forget that the dust on the contacts can also cause the failure of the hard drive or disrupt the flow of signals coming from motherboard and vice versa. Purge or clean the inputs and loops of the hard drive. An ordinary eraser, alcohol and cotton buds are suitable for cleaning the circuit board. Try not to fill the contacts - otherwise the drive will stop working at all.
- In case of a positive result of cleaning the loops and controller board, it is recommended to defragment the hard disk and registry.
Disk Data Recovery - Common Types of Failures
It also describes in more detail some specific problems and disk corruption. For hard drives, electronic and mechanical parts are mostly defective. Despite the fact that in autumn there are different solutions for shawls, classic discs are still susceptible to shocks. Therefore, it is more reasonable to manipulate them during operation. This is a problem, especially for netbooks and laptops. With the advent of high-capacity drives, a paradoxical cause of defects also appears: a small amount of stored data.
DIY hard drive repair video
There are a lot of videos on the Internet that demonstrate several ways to troubleshoot a hard drive. They are mainly related to disassembling the hard drive enclosure and cleaning board elements. This is due to the fact that almost 90% of hard drive crashes occur due to oxidation of electrical contacts.
Do not repair a damaged drive at home.
In practice, we encounter disk failures, which have a small defective surface, but in places where important data is stored. By simply deleting accidentally deleted data through some of the available programs, people at home tend to cope, but with more complex errors it is hardly advisable to intervene in the "do it yourself". Especially if lost data is important and it is really interesting to recover. In this case, often irresponsible internal interference in these media is irreversible.
Identify locations requiring eliminate oxide and dirt not difficult. These contact paths look darkened. To get started, carefully walk the eraser until a bright shine appears. Be sure to clear the group of contacts going to the drive (usually 3 of them). Next, we take alcohol and an old toothbrush - with their help, we additionally wash the contact paths.
Backup, avoid rescue problems
At the same time, this could be a common disorder that professionals can play with. No data will be saved anymore. For example, if you turn off your computer in the standard way, it will write to disk, and you can, for example, overwrite the places where the deleted data was saved. Also avoid further work with disk data through various programs, if physical damage occurs, try to prevent excessive impacts and sudden movements of the disk. When readers accidentally go through the disk plates, they will be scratched and damaged. do not try to disassemble a disk in a home environment using self-help, change the electronics of a disk, etc. the rest of the data on the disks is constantly submerged or, for example, you subtract the storage structure. Solving such additional damage is also a nut for professionals. If you find a problem, immediately disconnect the drive from the power source. . In a stream of cheap drives and high power, people often forget about back up data.
Now you need to protect the elements of the board from further oxidation. In principle, you can even cover silicone grease. It does not pass current, but protects against corrosion. However, it is best to treat the contacts with special aerosol agents. For example, Kontakt 60. When using a laptop for office or home use, we recommend performing such cleaning of the hard drive boards at least 1 time per year.
Currently, hundreds of films and TV shows, thousands of music albums or hundreds of thousands of photographs can be played on discs, but this data may not be available. Just one unpleasant crushing of funds during operation. if you have backup copy, probably no. But who honestly supports the data today? After this time, it is recommended that you save the disk to an archive or make another disk and regularly archive important data. Firstly, it was possible to bypass this part of the password-related overhead data found and deleted. Rescue was quite difficult, as it is one of the most hard disk hardware drives. Now we have learned to dive deeper into the service data. We discovered other mechanisms for how it works on these drives. A perfect knowledge of the internal mechanisms and the whole principle of the functioning of the disk is crucial in these cases of data recovery. Data recovery now takes less time, and for some troubleshooting tips, we have also increased the likelihood of data recovery from disk. Now we have accelerated the process of rescuing data from them.
- We can decrypt the password-saving algorithm.
- Therefore, we read the password directly.
If the described tips and methods for repairing a hard drive with your own hands did not help to fix the problem, then the best option is to contact a specialized center. The main thing is not to get involved in self-troubleshooting, and in no case do not listen to recommendations on various forums about what will help the heating of the hard drive or its stay in the microwave. This will only harm the device and take your time.
Go to the next page where you can find out everything. Over the past 50 years, special drives have undergone numerous changes in physical size, storage, cost and performance. Until the 90s, disks were not installed inside the computer.
Data backup. . See if this is in My Computer. If not, follow the step. Look at the external drive in the disk management window. The disk management window will open. Check the external drive in this window. In this window you can find your disk, even if it is not recognized, because there is no partition. If you cannot find the disk in the disk management window, you can go to step 4. Step 3: If it is not recognized by the connection to another or does not appear in the disk management window, an external disk problem may occur.
