Diagnostics and hard drive recovery program. Hard disk recovery. Where to download HDD regenerator

Recovery problem hard disk and the information that was stored on it - one of the most relevant on this moment time. Due to the seriousness of the issue, it is advisable to always have a tool on hand that could troubleshoot the drive. It can be as a complex program for HDD recovery and a utility that can diagnose a specific functionality of the disk.

HDD Regenerator - program for recovering broken sectors of hard disk and create recovery bootable disks. Its main advantages include a simple interface without unnecessary problems, the ability to monitor the state of the HDD, as well as support for different file systems. And the disadvantages are that official version the product costs almost $ 90 and the fact that using this program it is impossible to recover information after formatting the hard drive. It removes only bad sectors and then only at the logical level.

R-Studio is a versatile program that is perfect for both recovering a hard drive after formatting and recovering damaged partitions. It works with a large number of file systems and is one of the most effective programs for recovering lost data. Also, its advantages can be attributed intuitively clear interface... Well, the main disadvantage is that R-Studio, like HDD Regenerator, is paid.

The program compares favorably with other counterparts due to the interface in the style of Windows Explorer, which allows its users to easily and quickly cope with the problem. Same Starus Partition Recovery has the ability to preview files before restoring them and has a built-in Hex editor, which will come in handy for advanced users. The price of such convenience is 2,399 rubles, which is also the main disadvantage of the program.

Acronis Disk Director

Another paid one, but very convenient and effective program to recover the hard drive after damage. It has extensive functionality and allows the user to do whatever he wants with the hard disk - from recovering damaged information to optimization. Fast, powerful, paid.

Free program for diagnostics and recovery of hard disk partitions. Its main task is low-level testing of the HDD and assessing its performance. The main disadvantages are that the program is no longer supported by the developer and has an overloaded interface that will be difficult for an inexperienced user to cope with.

With the help of most of the considered programs, you can easily manage hard disk partitions, recover lost and deleted data, and also carry out diagnostics. HDD operation... Unfortunately, almost all of them are paid, but they have trial versions or demo modes. Therefore, you can try and evaluate the work of all programs, and then choose the one that you like the most.

If you accidentally delete files, format the disk, or errors in work hard disk you need to remember:

It will not be possible to recover data by means of the OS itself, so we use third-party hard drive recovery programs;
We try, if possible, not to use the disk from which we need to recover data at all.

Deleting files and emptying the recycle bin does not directly delete data on the hard drive. The reason for this is a rather lengthy process. complete removal... Therefore, in order to speed up the deletion of files, such "invisible storage" of documents was invented. If another document is written in place of the deleted document, it will already be irrevocably deleted. Therefore, whenever possible, of course, we do not perform any operations of copying, deleting or moving data.

We are looking for a program that suits our requirements.

Now we are just going to deal with the third point.

It should also be noted that disk recovery is a rather lengthy operation. So be patient. During recovery, it is not recommended to perform any actions with files on the disk (copy, delete, move). Such actions can only spoil everything. If your OS is installed on a disk that you want to recover, then the best option would be to write the program to a USB flash drive or disk and boot through them, and not through Windows.

In this article, I would like to give a list of programs for recovering data from a hard drive. These programs can be said to be universal and are suitable for data recovery not only with hard drives, but also with SSD, SD memory cards and USB flash drives.

Appointment

Hetman Partition Recovery is the flagship product. The innovative algorithm used by the company makes it possible to find and recover almost all files in full in the vast majority of cases.

Recovers any files deleted from a hard or USB drive, memory card or any other media, regardless of memory size and manufacturer. The software will successfully recover the data lost since personal computers, laptops, digital cameras and other gadgets. Low-level internal content search algorithms will return documents in the most difficult cases.

Recovers information from formatted, deleted partitions or disks after changing the file system from FAT to NTFS (and vice versa). Hetman Partition Recovery finds and analyzes any data saved on the disk. Even if the file tables are empty or completely absent, the utility will restore the lost by applying algorithms for finding information by the signatures of the beginning and end of the document.

Successfully recovers files deleted using the "Shift" + "Delete" key combination, deleted by a third-party software or lost as a result of emptying the Windows Recycle Bin. Work in the "Quick Analysis" process takes only a few seconds, in the "Deep Analysis" mode, the program examines the entire surface of the hard disk and returns all available information.

Recovers information destroyed or blocked as a result of virus attacks. Viruses, "Trojans" and other types malicious code may intentionally destroy information or make it inaccessible by modifying or deleting important system structures disk. The utility is equipped with a series of innovative algorithms that successfully extract information from infected hard drives.

Recovers information lost after system or hardware failures, physical damage, power outages, or driver errors. Often, errors in the system firmware of the disk ("Firmware") lead to the deletion of important documents.

A logical disk may be damaged or not accessible at all if a lengthy file copy operation is interrupted by an operating system crash or power failure. The utility successfully reads information from damaged, unreadable and inaccessible disks and opens access to lost or inaccessible files.

Possibilities

It is a versatile tool for a successful solution typical problems associated with deleting data, it supports both scratch disks and inaccessible and damaged logical partitions and returns information so that it does not become the reason for its loss.

File formats

Returns deleted files regardless of extension:

Text Microsoft documents and Open Office (DOC, DOCX, ODT, RTF, PDF, etc.);
Digital images (JPEG, PSD, EPS, TIFF, PNG, etc.);
Spreadsheets and presentations (XLS, XLSX, ODS, etc.);
Compressed archives (ZIP, RAR, etc.);
Video and audio recordings (AVI, DAT, MKV, MPG, VOB, MP3, etc.).

Recovers hard, external USB and SSD drives

Hetman Partition Recovery works with hard and external USB drives(interfaces IDE, ATA, SATA, SCSI, etc. are supported), as well as with any other devices, connected USB cable to the computer.

Supports memory cards (SD, MicroSD, SDHC, Compact Flash, Memory Stick, etc.) used in Mp3 players, tablets, cameras, mobile phones, smartphones, video recorders, GPS navigators.

Works with USB solid state drives from various manufacturers (A-Data, Corsair, Goodram, HP, Kingston, LaCie, PhotoFast, PNY, SanDisk, Silicon Power, TDK, Team, Toshiba, Transcend, Verbatim, etc.).

Ease of use

The recovery process is very simple and takes place in 3 stages. By answering simple questions from the built-in "Wizard", you will find deleted files in a few minutes. The interface resembles the standard Windows Explorer window, which displays both existing and deleted files and folders. Moving from folder to folder and viewing the contents of the found documents, you will quickly select and save the desired objects. Detailed documentation is fully translated into Russian.

Hard disk analysis methods

Master File Table

Documents are stored as sequences of bytes written to HDD one after the other or chaotically scattered over its surface. The logical disk driver keeps records of the sectors in which the information with the contents of the file is located in a special table. When deleting with "Shift" + "Delete" or emptying the "Recycle Bin", the operating system marks the sectors in this table as free and available for writing new objects. The utility analyzes the contents of such a table and opens access to remote files to the user.

Disk file system structure

System errors, virus attacks, physical damage, deletion or formatting logical drives lead to full or partial overwriting of the Master File Table and, as a result, the loss of important documents. The program finds file tables using all the preserved disk system information (partition tables and their fragments, master boot record), processes and extracts the contents and service attributes of lost files.

Disk signature analysis

Often the contents of a file are saved on disk in full, and information about where it is stored is overwritten with new files. Signature Analysis recovers files based on their contents. When it detects a specific sequence of bytes on the disk (eg, "49 49" or "4D 4D" for a TIFF file) indicating the beginning of the file, the program reads and displays its contents to the user. The utility is unique in that it combines all the above recovery algorithms. The result of the work exceeds the capabilities of most specialized laboratories.

Preview and HEX editor

Trial version allows you to analyze the storage medium and view the contents of files found for recovery. If the file is displayed in the area preview, then it will definitely be restored in full. In addition to previewing deleted images, documents, spreadsheets, multimedia files, compressed archives, the utility has a HEX editor. Using the HEX editor, you can see in which sectors the contents of the deleted file lie, and also view service information O logical drives or the entire physical medium.

Hard disk recovery security

Any operations with files (for example, creating, editing, viewing and saving) lead to changes in the records of file tables and to full or partial rewriting of the content deleted files... In the case of working with a "broken" disk, every minute of work can lead to the failure of the entire medium and the irrecoverable loss of a part of the data. Hetman Partition Recovery is designed to meet all the security requirements for a professional hard drive tool. The hard disk scan is performed in read-only mode. The utility supports the creation and subsequent recovery of data from virtual image, which significantly reduces the running time of the failed disk.

Saving results

For most users, the hard drives of computers and laptops are filled with valuable information: family photos, work documents, etc. During the process of saving the recovered data, you cannot use the disk from which the files were deleted. This will completely or partially overwrite the lost files.

Hard drive problems are very common, and many users do not know what to do in such situations. And every program for repair hard the drive is designed to take specific actions depending on the type of failure. Further it is proposed to familiarize yourself with some types of crashes and by software to eliminate them.

Checking and repairing your hard drive: Windows programs and tools

Before using such a tool, you need to find out the nature of the failure. Among the main types, the following can be noted:

violation of the structure of the file system;
damage to the surface of the hard drive;
software errors;
loss of information due to failures or formatting.

Do not underestimate the funds presented in operating rooms Windows systems... Repair program for hard Windows disk 7 or any other system is called ScanDisk and, in the simplest case, is called from the section properties menu, where the scan start button is used on the service tab.

In this case, you need to specify the automatic correction of bad sectors, and if you wish, you can also use the surface check.

However, using a similar applet (chkdsk) called from command line(cmd) running as an administrator in the Run console looks much preferable. Additional attributes must be entered for this tool. Among the most commonly used, one can single out a check with a space-separated combination of / f / r and / x / f / r. If system components are damaged, you can use the sfc / scannow command.

The best applications for the treatment of hard drive and data recovery

In order not to engage in the above procedures, many users use and third party utilities, among which the following can be singled out separately:

HDD Regenerator.
Viktoria.
R.Saver.
Acronis Recovery Expert.
Hetman Partition Recovery, etc.

Immediately, we note that applications like Recuva, designed to recover deleted files or missing information from damaged HDDs, will not be considered only because of their absolute inefficiency.

HDD Regenerator

HDD Regenerator is a relatively recently developed program for diagnosing and repairing a hard drive, designed not for recovering lost information, but for finding problems associated with physical damage hard drives or software glitches.

According to its creators, the operation is based on the principle of magnetization reversal of the HDD surface, which allows for a complete restoration of the hard drive's performance. It works in DOS mode, which causes some problems for users to use, however, in some cases it shows good results when no other tool helps.

Viktoria

According to most professionals, the Viktoria hard disk repair program from Belarusian developers is the best in its field and allows you to eliminate many software problems associated with the file system, the appearance of bad sectors, etc.

It can be run in two versions: in DOS mode emulation and as a standard Windows application. However, as noted, it is better to use the first method, since checking in this mode is more effective, not to mention the elimination of crashes and errors (such as the difference in startup standard tool Windows).

R.Saver

R.Saver hard drive repair software is designed to recover deleted or lost information. Its use is justified because the utility is able to find files, among which there may be important system components, even after formatting a disk or logical partition, completely reconstructing the file system.

Scanning, however, takes a lot of time, but the application finds files that the user may not even know about. And in most cases, it is the application of this program that is the best option even for removable USB HDD, flash drives and memory cards of any standard.

Acronis Recovery Expert

This hard disk repair program is mainly used when the structure of the file system is broken and even allows you to create bootable media for those cases when it becomes impossible to start the OS from the hard drive.

At the same time, the application has support huge amount file systems and large hard drives.

Hetman Partition Recovery

Although this utility is positioned as a means of recovering information if it is lost after formatting or in case of software failures, it can nevertheless be used to find problems with the HDD.

The main advantage of the application is that it can be launched both in manual mode and using a special "Wizard", which makes it possible to automate the processes of analysis (scanning) and data recovery.

Outcomes

These are not all programs capable of performing maintenance on hard drives, but only a few of the most popular ones. But even brief acquaintance with them allows any user to understand the principles of their operation and scope. If you recommend a universal solution, at the first stage of the repair, you need to use the system tools (if possible), HDD Regenerator or Viktoria, and for the subsequent recovery of information - R.Saver or other software products.

In this article, we will tell you about recovering bad sectors of a hard drive and the reasons for their appearance. Step by step instructions help you prepare for this procedure and cope with it yourself.

What are broken sectors

Let's take a quick look at the structure of the hard drive. It consists of several individual discs, above which there are magnetic heads designed for reading and writing information. When storing data, the heads magnetize certain areas of the disk, divided into tracks and smaller components - sectors. It is in them that the units of information are stored. If the sector becomes unavailable for reading, it is called "broken".

Several signs indicate the appearance of such a problem:

squeaks, rattling, tapping when the disc is working;
heating of the HDD surface (in a normal state, this should not happen);
frequent errors when working and starting the operating system.

Typical Causes

The main reasons for the appearance of broken segments of the hard drive are:

Also, malfunctions of the hard drive may appear due to mechanical damage. They are often caused by dropping the hard disk or computer, damaging the magnetic surface (for example, during transportation). Non-working parts also appear due to factory defects. In this case, they may not appear immediately, but "fall down" over time, rapidly increasing their number to a critical level.

Important! If you suspect mechanical damage or marriage, you should immediately contact a specialist or exchange the hard drive under warranty.

Recovering bad HDD sectors using Victoria

If the appearance of broken segments is associated with software failures, then they can be restored using specialized software... One of such programs for recovering bad hdd sectors is Victoria. The utility is available in two versions - for Windows and DOS. The most effective recovery will be through DOS, since when the OS is running, some sectors may be busy, which means they are not available for scanning.

Victoria HDD - diagnostic program

Scanning

To get started, we need to do a little preparation. First, you will need a disc with a program image recorded on it, or bootable USB drive... If everyone can cope with recording an image, then it can be difficult to create a USB flash drive.

Let's dwell on this step in more detail:

Note! The program takes up very little space, so after installing it, the drive can be used to store other information. In order not to accidentally delete the files necessary for the utility to work, it is recommended to allocate a separate folder for them.

Let's start the scanning process:

Here we need the item "Reallocated sector count", which displays the number of fragments in the reserve zone, as well as "Current pending sectors" where the parts that cannot be read are displayed. If their number is not very high, then the disk should be recovered.

Hard drive recovery

Let's see exactly how this process takes place. Problem segments can be roughly divided into two types. The first ones are not readable due to the mismatch of the information stored in them and its checksums.

This error occurs during a power outage when new data has already been written and the checksums remain old. They simply cease to be recognized and are restored quite easily - by formatting them and writing the correct amounts.

The second type occurs as a result of mechanical damage. In this case, recovery is more difficult, but still possible. The resumption of the performance of such parts is carried out through the use of reserve areas that are on each hard drive.

We begin to recover each of these types of errors.

Video: HDD - "curing" bad sectors

First, let's try to fix the bad sectors by erasing the information stored in them:

press F4 and get to the check menu;
in the menu for selecting operations with unreadable sectors, specify "BB: Erase 256 sect" and press "Enter".

A lengthy process of scanning and restoring bad sectors of the HDD will start. If the program finds a bad sector, it will try to erase it, thereby correcting the error. If a mechanical defect is present, an error will be reported. In any case, you need to wait until the check is complete and then separately fix the sectors with physical faults.

For this:

Now the restore operation will work on a different principle, trying not to erase bad sectors, but to replace them with space from the spare area.

Important! If there are a lot of such sectors, then the spare space may run out. This will be reported by special message, and further recovery will become impossible.

After successfully recovering bad sectors on the hard disk, it is recommended to perform a full check of the file system for errors.

This can be done using CHKDSK utilities or in the following way:

Photo: checking the disk for errors

Attention! In order for the system not only to find, but also to fix the problems, before starting the scan, select "Automatically fix system errors".

The methods described above will help you easily cope with non-critical cases of the appearance of problem sectors, find and fix them. Accurately following our instructions, any user can do it on their own, even without having a computer education. Hope that this information was useful to you.
