How to recover deleted information from hard disk. Saving to a remote server. Hard disk is detected but not working

If you accidentally delete the information you need from the computer's hard drive, this does not mean that you have completely lost it. Any file, even after formatting hard drivecan successfully recover. Especially if after its removal new information was not recorded on the hard disk. But even if time elapsed after deleting files, new files were recorded on the hard disk, chances for a successful recovery still remain. To restore the information you need a special program.

You will need

• - a computer running Windows;
• - Filerecovery application;
• - TuneUp Utilities program.

Instruction

Recover lost data will help the application Filerecovery. Find this program on the Internet, download and install it on your computer. After installation, run it. In the left part of the main menu of the program you will see all partitions and all hard drives that are installed on the computer. Mark the hard disk partition or directly the hard disk from which you want to recover information.

After the partition of the hard drive is marked, on the toolbar on the top select Quick scan. Starts the process of scanning a hard disk partition. Upon its completion, all found files in the form of a list will be displayed in the program window. Select the files with the left mouse button, and in any part of the window where the found files are displayed, click the right mouse button. Will appear context menuin which click on the Recover command. All files will be restored.

If you need, for example, to restore not a large number of files, but only one, then this method is better for you. Download the program TuneUp Utilities from the Internet. There are its free trivial versions. Install and run the program. In the main menu, select the tab "Repair Problems", and then - "Recover deleted files." Further in the window, mark the partition of the disk from which data will be restored.

In the next window, in the “Search criteria” line, enter the file name (approximate) and click “Next”. Wait for the process to search for files with the selected name. If the file is found, it will be displayed in the program window. Click on it right click mouse, then select "Restore". The file will be restored to its original folder. If the original folder has been deleted, then you have to choose which folder to restore the file to.

Many of the users of computer technology have come across (and will face) the fact that they may need to recover data from a hard disk. It is enough to imagine a situation where a user is working on a computer and trying to gain access to documents or some important files stored on a hard disk, but, to his surprise, he discovers that the necessary data does not open.

Such a situation may arise as a result of HDD breakage. The reasons for the failure of the drive can be many, and to decide whether it is possible to recover deleted data and how to do it, you will have to try a little. I must say right away that there is no need to panic ahead of time, because many problems are solved on their own. There are several ways to recover data that you can try yourself before contacting the wizards.

Loss of information may be associated with a number of factors, but 3 of them are considered the most common.

• First, sometimes the user accidentally deletes an important folder, cleans the recycle bin, or even formats a hard disk by mistake.
• Secondly, the problem may be related to the software. In this case, you can try to restore the files in any way.
• Third, the cause of the data loss may be related to the problem with the hard disk itself. Given the complexity of modern drives, it is not surprising that something can go wrong somewhere. If the HDD suffers from some kind of system or hardware error, then an ordinary user is unlikely to solve the problem on his own. In this case, it is best to contact a special service, where they restore files from the disk. However, there are a number of errors that you can try to solve on your own.

Data recovery using special programs

Now we will analyze how to recover data from a hard disk using various software and utilities. If you lose data, you need to act as quickly as possible. If the drive is connected to a working system, then with every second the chances of its recovery decrease.

The operating system constantly writes and reads data from the hard disk, regardless of whether the user is at the computer or not. Usually, a remote directory is perceived by the system as free space, because of which it can overwrite this area, reducing the chances of recovering information.

Procedure

You must shut down the computer to which the damaged disk is connected. After that, the archive of files will be safe from overwriting, so that it can be cloned and try to recover data from an exact copy. There are several cloning methods. Then you will need to use the program to restore information. For this purpose, many various applications   and some of them are free.

Recuva is good program   recovery deleted fileswhich does not require investments. The program for recovering files from an external hard drive, known as Zero Assumption Recovery, is suitable for those who are willing to spend money on a good application.

Data Recovery for Hardware Failures

How to recover deleted files from hard disk? Search for remaining information using software   - it is very convenient. But what if the erased disk is not even detected operating system? Sometimes it also happens that the computer sees the folders and files, but freezes when trying to access them. In the worst case, the disc may be completely disabled, as a result of which it will not even spin. It is necessary to study the main components of the drive and try to understand which of its components could break. Different breakdowns can be accompanied by different symptoms:

A PCB is a chip that attaches to the bottom of a disk (usually it is green). Here is the main controller (equivalent to a processor on motherboard) along with other electronic items. This interface converts binary code into information that a computer is capable of understanding.

Platter is one or more thin round plates. On conventional consumer HDD, they rotate around its axis at a speed of from 5900 to 7200 r / min. This is the item on which the data is stored. It is made of glass or various alloys and is covered with a magnetic layer, so that it can store up to 4 TB of information.

Head Assembly are special heads for reading and writing data. Interestingly, in the course of their work, they are not in contact with the surface of the plate. These heads are located slightly above the disk surface. As a rule, each plate has 2 such devices. Large HDD with 3 plates equipped with 6 heads. Such devices can fail as a result of a shock or a strong shake. As a result, they cease to hover over the plates and enter into direct physical contact with them, which is why information on the hard disk begins to erase at a speed of several thousand revolutions per minute.

Firmware is built-in HDD software, which is an operating mini-system that provides access to data storage. Most of this firmware is stored on the plates. A relatively small fraction gets the chip, which is necessary to start the drive. The firmware may fail, causing the data to become inaccessible.

Unfortunately, hard disk firmware is not similar to analogs for smartphones and tablets, so they cannot be updated or rolled back to previous version. Each HDD model has its own unique modules and parameters. Programmers sometimes joke that every hard disk is complex.

What to do if the disk does not rotate

How to recover information from a hard disk if it does not rotate. This is the case when the user has a good chance of recovering deleted files. But in this case, you will need some effort and time. If the disc does not make any sound when connected to power, then with a 99% probability the problem lies in the PCB. For older models of drives, it was possible to find a suitable chip from another drive in order to make a replacement. On new drives, technology and architecture have changed. Now each HDD contains a unique microcode. In modern conditions, the replacement of the PCB has almost no chance of success and can be dangerous for the remaining data.

There are 2 possible causes of a microcircuit failure: the TVS diode (fuse) has failed due to a short circuit, or some other vital component has suffered. Boards on drives often have 2 TVS, which protect the drive from power surges. Usually 1 of them is designed for 5 V, and 2 - for 12 V. If the user accidentally connects the wrong power adapter to the hard drive, or a power surge occurs, then the diode may fail. If the TVS suffered as a result of the short circuit, and the remaining components of the chip are in perfect order, then removing the diode will be enough to restore the performance of the HDD.

The status of the diode can be checked with a multimeter. If the device shows 0 Ohms or something, then TVS has really closed. Diode failure can be accompanied by a noticeable smell of burning and visual changes similar to burns. It must be borne in mind that after removing the diode, the drive will remain defenseless, so the power source must be uninterrupted and reliable.

If the TVs do not smell burnt and show the correct numbers when measuring, then the problem lies in the PCB itself. In this case, the need to replace the chip. Most chips have an 8-pin ROM chip that contains the unique firmware needed to run the drive. The replacement will work only if the element is transferred from the old PCB to the new one. Some hard drives (especially Western Digitals) do not have such an 8-pin chip. Instead, the firmware is stored in the main controller, which is almost impossible to disconnect.

If you want to replace the IC chip, then it must be suitable. You can find professionals who are engaged in similar operations. Some of them even offer replacement ROM, eliminating the user from the hassle associated with a soldering iron. If the PCB is the only damaged component, and all other elements are in order, then after the replacement, the disk should work again. Another element of the chip that needs to be checked is contacts. Over time, they can corrode, but are easily cleaned with gum.

What to do if the drive emits clicks or freezes

How to recover files from hard disk? Strange sounds are a serious problem with reading and writing heads. If these devices break, then they begin to spoil the plates with information. In any case, this is a job that only professionals can do. The drive must be opened in a special laboratory and the damaged head must be replaced in order to get to the deleted data. If the disc emits clicks, it is better to turn it off and leave it alone, in order to send it to a special company engaged in repairing drives. It is not recommended to turn on the HDD with such a breakdown, since its condition may deteriorate further.

How to recover files on your hard drive? A freeze means that the disk has started to demagnetize. It appears a large number of "bad" sectors, which the drive tries unsuccessfully to read, because of what eventually freezes. Typically, this problem occurs over time, and it can only be solved with the help of professional data recovery equipment, called the Hard Imager. If you examine a hard disk using SMART technology, then you will notice a large number of redistributed sectors to confirm your suspicions. You can save scan results and send them to experts who will be engaged in recovery.

If you still want to carry out this operation yourself, while at the same time risking to exacerbate the problem and destroy the remaining data, you can try to use Hard Imager yourself. But it must be borne in mind that such software works through the BIOS. An alternative is the free dd_rescue application that runs on Linux. It can skip all bad sectors on an external disk and save the remaining information.

What to do if the disc beeps when turned on

A sound like a squeak means that the HDD is trying to unwind, but cannot. The problem can only be caused by serious mechanical damage. Most common possible reason - This is a phenomenon called "stiction" (stickiness). When the disc is not used, its heads can be located in the center or on the edge. As mentioned above, these devices do not touch the plates, but hover over them. Sometimes the head may take the wrong position, because of which the disk stops rotating. Because of the extremely smooth surface of the plates and heads, they can literally stick to each other. The disk must be opened in the laboratory, where the defective items must be replaced with new ones.

Another reason could be the breakdown of the engine - a mechanism that spins the plates with information. It may jam if the hard drive gets hit. Such a failure is quite rare, except for Seagate discs, in which the engine is extremely fragile. There are 2 ways to solve this problem, but in both cases, professional intervention will be needed. You can replace the engine, or vice versa - remove the plates with the heads and install them on another mechanism.

What to do if the hard disk is not detected

As a rule, this indicates a problem with the firmware. A few years ago, this error was widespread with Seagate products. Many disks with the SD15 firmware version suffered from internal system failures. This error caused a large number of hard drive crashes. In those days, such failures could have been eliminated on their own, but modern HDDs, as a rule, require the intervention of professionals.

Summarize

So, in some cases, you may need a program to recover data. Sometimes the loss of information may be due to the fact that the user accidentally deleted it. If the disk does not show any signs of life at all, then the problem is in the PCB chip. In the case when the drive emits unusual sounds and generally behaves strangely, you need to pass it on to the professionals who will recover the information on the hard disk. Any attempts self search   missing information are risky. If the recovered disk really stored vital data, then it is better to spend a certain amount of money and give the HDD to the recovery service.

In each case, the cost of data recovery is calculated individually. The master will be able to tell the final price only after diagnosing the faulty device. Usually the cost depends on:

• the nature of the fault;
• reasons for the disappearance of data;
• the time spent by the master on information recovery;
• need to replace components.

The site contains approximate prices that will help you understand how much money will be needed to recover lost files.

Free diagnostics

The center offers customers free diagnostics of devices. If this is possible, then it is held in the presence of the client and takes no more than half an hour. At the end of the wizard can accurately determine the nature of the problem, the timing and cost of data recovery. If everything suits you, the specialist will start working. To order a service you need:

• leave a request on the site;
• talk with a specialist and tell him about your problem;
• agree with the master about the time by which you will be comfortable to take it.

Payment of data recovery services is carried out after the fact. If the result is absent or does not suit you, then you can not pay.

Trust the professionals

Very often, the data recovery center is addressed to the client, whose carriers have already passed through the hands of private masters. Unqualified intervention not only does not give any results, but also significantly complicates the work of specialists. There are situations that due to incorrect actions of pseudo-skilled workers, data recovery becomes impossible.

If you do not want to lose your data, then contact a reliable specialist. Do not experiment with suspicious software from the Internet. This, as a rule, is not only not beneficial, but also complicates the recovery of information. Attempts of independent manipulations can lead to irretrievable loss of data!

Confidentiality of information

Not only personal information is stored on digital media, but also commercial secret files. Therefore, the issue of confidentiality is very relevant. Computer service ensures the secrecy of your data. In the process of restoration of files, the possibility of their direct viewing is excluded. All information is read sector-by-sector. The integrity of the files is not checked manually, but by machine structural analysis.

One of the main brain centers of each computer can be considered a hard disk. Thanks to him, we can memorize information and store it, regardless of its nature. But, like any other mechanical device, the hard drive is subject to wear and the risk of other negative impacts: viruses, hackers, power surges, hardware failures, user errors, which certainly leads to loss of information stored on the computer. And then many users may be faced with the question: how to recover data from a hard disk? Next, we will consider several ways to do this, they can be used in different situations, and also use them as additions to each other.

How to recover data from hard disk?

The simplest type of data recovery is to access a backup copy of files. However, this is possible only if they were previously created, as well as in the absence of significant failures in the drive. Once some data loss has been detected, you must turn off the computer from the network. In general, it is worth relying on a special automatic program in the matter of creating backup copies. If they were not created in advance, then you should not despair at all. When deleting data on disk sectors, information about files is saved, and if they are not overwritten, the data can be restored by creating a full copy of the disk and using a special Live CD utility. It is important to note that at the moment the most common method of data recovery is the use of various kinds of software, but this method can hardly be called the most effective. Utilities are not always able to recover data efficiently and correctly. This is especially difficult given to the user who has little experience with them. Sometimes with the help of such programs can only be applied after which it will be impossible to correct the situation.

If you are concerned about how to recover data from a hard disk in case it was lost due to a malfunction in terms of hardware, then only mechanical manual intervention will be required. Such a procedure may be useful in case of damage to the disk surface. This part consists of a thin layer of crystals, some of which may crumble with time. The magnetic layer is sometimes damaged due to the incorrect operation of the drive head. All these devices need to be repaired for data recovery, as well as to prevent their further loss. This is a difficult and painstaking work.

Recovering data is a more complicated procedure in case of damage by spyware or malware. With such an attack, you must immediately create backup copyand also stop working with the computer. The data can then be restored by referring to the file table. Information on the hard drive may be under threat due to errors in its boot sector. Sometimes, because of this, the computer does not even recognize. But even here there is an easy way to recover: you will need to boot the computer from another medium, after which access to the information will be open. You can even recover deleted photos.

Often the loss of information is associated with damage to the file system itself. In this case, you will identify the problem by incomprehensible characters appearing on the screen when you try to open the file. And here it is important not to write anything to disk. Data may be permanently lost due to any information entered.

Answering the question of how to recover data from a hard disk, it is worth noting that it is more correct to try to prevent any losses and related problems than to seek a solution.

Quite often, PC users are faced with an unpleasant situation when you need to recover the missing data from the hard disk, which was erased by mistake or accident. The system marks such data with “zero”, after which other information can be written on top of them. When writing other data, when the user fills up the free disk space, the original files will be lost forever.

What not to do, and what is better to do:

• In no case do not install the program and do not save files to the disk on which the lost files were located - this will increase the chances of their successful recovery.
• For further work it is recommended to use external drive.

You can contact the experts to extract the data, but their work is usually too expensive. To make the recovery yourself is also quite realistic.

How to recover data

There are special programs that allow you to restore all necessary files. For the most part, they are suitable not only for working with computer disks, but also for external media.

It is likely that information will only be partially restored, but this will have to be put up with. To get the best result from the data recovery program, you should install it on an external disk, run it from there and follow the instructions.

In this article, we will look at the process of recovering files from a flash drive using a free, but very effective R.Saver program (official site), which can:

• recover deleted files;
• reconstruct damaged file systems;
• recover data after formatting;
• recover files by signatures.

At the end there will be a list of other programs with which you can try to recover your lost data.

We will check how R.Saver recovers files after standard deletion from storage media. To do this, take an ordinary USB-stick with file system   NTFS, create a separate folder on it, save several different files into it, and then delete them.

Next, download the archive with the program, extract the files (extract the files to the wrong partition from which to restore), and run the r.saver.exe file. The tool is portable, works without installation.

In the main window of the program we call the context menu and select “Search for lost files”.

In the next window, click "No", because we deleted the files manually, and not by formatting.

We are waiting for the scanning process to complete.

After scanning we will see remote folder, and inside it are our files.

Determine the storage location, click "Select".

That's all. Files have been successfully restored and saved to local disk   computer.

Other programs to recover deleted information

Recuva

One of the most promising products. The program is free, Russified and does not cause difficulties in mastering. Recuva will find the deleted files from the computer or on external media and immediately restore them. After downloading and installing it on a computer or external drive, do the following:

• After starting the recovery wizard, mark all data that should be restored;
• Mark the section or folder where the lost data was;
• After this, the scanning of the selected folders and the search for deleted files begins. Longer time, but showing better results, will be a function of in-depth scanning;
• Then Recuva will output the data that was lost from the hard drive or external media. For external media, the sequence of actions will be the same as for the hard disk;
• The program highlights all the data found in different colors. Greens - which were completely removed, yellows - which were partially restored, red - that remained deleted with the loss of all information.

At the final stage, you need to mark the folder where all files will be saved.

R-Studio

Paid but professional program. In demo mode allows you to recover files no larger than 256 KB. Recover all accidentally lost or missing from formatting or virus attack data from the hard drive or from removable media. In the list of supported appear all popular windows versions. Practical interface and advanced functionality with additional features   will please the most demanding users. The algorithm of action after downloading will be the following.
