A hard drive is an essential part of a computer, because if another component breaks down, it can be replaced painlessly, and changing a hard drive that stores important information is problematic. Upon exiting building hard All data on it can disappear without a trace. Therefore, when a hard drive crashes, many are interested in: “How to restore hDD?».
But what if this information is damaged or is no longer available?
The drive must be diagnosed to determine the reason for which it was not possible to detect. It could be a cable, or it could be a head wreck. The answer can be for many reasons. Special equipment, which is very expensive and requires a highly qualified specialist to use it effectively, is required in most of these types of data recovery cases.
These are real-life descriptions of the requests we receive daily through our online quotation form. The computer does not recognize the hard drive. . Do you ever need to reformat your disk or partition when programs continue to crash or other strange problems occur on your system? However, something discontent caused by reformatting will force you to seek data recovery after reformatting, especially for people who know little about the computer. Well don't worry software data recovery designed to recover data after reformatting with hard drive, will greatly help in solving problems associated with the reformation of disks.
As a rule, before a breakdown, the hard drive either makes strange sounds, or is not detected by the operating system. There are 3 main problems:
- BIOS does not see the hard drive. Most likely, the drive electronics is out of order. If it contains the necessary information, then you can contact the service center, where it can be transferred to another medium.
- There was a noise during the work of the hard drive. If the disk is still functioning, then urgently need to transfer all the necessary information to other media, such as DVD or flash drive. This problem is associated with a malfunction in the drive of the drive, it is easier and cheaper to buy a new hard drive than to give it for repair.
- does not see Windows. With such failures, it is almost always possible to restore full disk performance. This can be done using special programs that can perform information recovery on the hard drive.
In case of possible malfunctions, it is best to take the drive to the workshop, because specialists know how to restore the hard drive. Of course, you can try to bring your hard drive back to life. To do this, it is necessary to disassemble it using a star-shaped screwdriver, carefully open it. After that, arm yourself with alcohol, rubber and cotton and wipe all the contacts. Sometimes this helps and allows you to restore the media.
Did the data really go after reformatting?
Absolutely, the feeling of using a computer is very exciting after reformatting. However, some people have avoided losing valuable and important data about their personal and business life during. Some others who suffer from data loss after reformatting believe that they cannot recover data after reformatting and feel despair.
High-level formatting is sometimes performed on the working disk to delete the contents of the hard disk. This is commonly called "reformatting." This leads to an empty disk in the operating system, which makes existing content inaccessible by conventional methods without destroying the content.
Some users are interested in: “Is it possible to perform recovery hard data disc after accidental formatting? ". Of course you can, but for this you need special programe.g. Hetman Partition Recovery. Using it, you can return information that was on the hard disk before deletion or formatting. The program is able to restore not only 80-90% lost information, but also the folder tree on your hard drive.
This way you can recover data after reformatting. Notes. To guarantee high-quality data recovery, do not do anything on the drive from which you want to recover if overwriting the data you want to recover.
Live Recovery Reformatting Tutorial
Steps to recover data after reformatting
If you lost a partition, select Lost Disks and Scan to continue the recovery process. This frequently asked question about repair options cannot be answered with a simple offer, because for repair hard drives It requires a lot of know-how, expensive technical equipment and, above all, knowledge.Simple enough and understandable, but let's take a closer look at how to recover a hard drive after formatting it. After starting the program you will need to select logical drivefrom which you deleted the files. If you need to restore the hard drive after formatting, you need to select a physical disk.
If the media is large enough, then the analysis may take long time, so for better use the search function deleted partitions. There are two ways to recover information:
Modern hard disks differ slightly from the original models in their architecture. Since then, this has not changed much over the years. To date, data is stored in magnetic form on magnetic disks inside the hard drive enclosure. The so-called read / write unit is still responsible for writing data, and the internal and external electronics of the hard drive handle the processing of these signals.
Mechanically Damaged Hard Drives
To return to the original question, we would like to explain with an example what is possible and what is not. In this case, the highly sensitive surfaces of the magnetic disk data medium and the read / write unit itself are affected. Under normal operating conditions, the read and write heads fly over the air cushion above the surface of the data carrier and do not touch it directly. If, however, a direct contact of the two components occurs, then they speak of a “head scratch”.
- Full analysis physical media. In this way, you can recover data after deleting, formatting, disk corruption, re-creating logical partitions. Such an analysis takes a long time.
- Quick scan. This method is suitable for people who want to recover recently deleted files. The scan time of the hard drive in this mode will take less than a minute.
After the analysis is complete, the program will indicate the number of folders and files found. Then open them in Windows Explorer. All information found will be marked with a red cross. You can start a file search by size, name and creation date. You can save files at various carriers, including CDs, servers, flash drives.
This translates into increased noise hard drive, usually a loud click or flicker is heard. A defective read / write block is still the least evil, because it can be replaced or replaced. Keep in mind that opening a hard drive should always occur in a suitable environment. The inside of the module’s hard drive is so sensitive due to its sensitivity that even the smallest penetrating dust particles can cause complete data loss. Hard repair The drive is no longer possible.
With 10 years of experience, we can solve 95% of all cases. As a rule, you should take into account that the opening and the corresponding equipment should be performed in a clean room, because after the surface of the data carrier is damaged too much, repair and successful restoration of data are no longer advisable for experts.
Now you know how to recover a hard drive after formatting and how to recover deleted files from a computer. With the help of a simple program, you can restore data not only on the hard drive, but also on any physical medium.
In previous articles, we talked about recovering deleted files from damaged media, formatted or inaccessible drives. Today we will try to find solutions to problems associated with damage to the most sensitive part of the hard drive; that part that contains information all about the carrier, its volumes and their configuration.
The most common causes of defective hard drives
We strongly recommend that you do not attempt to repair the hard drive yourself. As already explained, a hard disk is a very complex storage medium that reacts very sensitive to disturbing influences. In the event of a motor malfunction, the read heads of the hard disk can no longer move. In this case, the hard drive should be immediately disconnected, as this may lead to further damage to the drive.
You can find out how this can be prevented. Deleted data can be recovered frequently. Whether it’s sensitive bank details, business documents or scandalous photographs that can be used to blackmail you, of course, you don’t want anyone to receive this personal data at your fingertips.
Corrupt boot records and partition tables
All data on the hard disk is written in a specific logical order. Most operating systemsincluding Windows, Linux, and Mac OS will initialize the physical drive by creating one or more logical drives, known as volumes or partitions. Simply put, each hard drive is divided into logical partitions during formatting. After formatting the partitions, the OS creates an empty file system, which, in turn, will contain entries pointing to real files stored somewhere on the disk.
Fortunately, you can safely delete your old data. Here you can find out how it works! Data deleted from this hard drive can be recovered. If you delete a file from such a disk, the file will only delete the file. Until the file is overwritten in the future, people will be able to check the hard drive and recover deleted files.
Empty external hard drives
For many years, computer users had to use third-party software to clean their mechanical hard drives before they dropped them. When you start the process, you can select "Erase disk completely." After that, you have a new system without any recoverable files. Deleted Files could theoretically be recovered from your hard drive. Perform full formatting external hard drive to securely destroy deleted files.
The first thing the operating system does when structuring a physical hard disk is to look for system records containing information about logical volumes or partitions. Moreover, different operating systems can use different formats (for example, MBR partition tables in Windows, or GUID Partition Table in Mac OS X), and in order to structure partitions as “volume letters”, the system should be able to read this information.
Disable the "formatting option" for full formatting - quick formatting does not completely delete files from your hard drive. Repeat this process for each hard drive that you want to erase. Clear free space. You can also use other disk cleanup tools.
Check your work: try restoring files
A full cleanup is safer as it ensures that everything will be deleted on your hard drive before installing a new system from scratch. Make sure you perform a “low scan” - it will take longer, but you will find more deleted data.
Use encryption to protect your data.
If you are worried that someone might recover your deleted data. Encryption protects all your data, both current and deleted. June price reduction. A disk on which all data has been encrypted and deleted should not show anything about you.But what if this information is damaged or is no longer available?
All information about logical volumes or partitions located on a physical hard disk is stored in several initial sectors. This means that due to damage to just a few small sectors, the entire hard drive inevitably becomes inaccessible. The causes of damage to highly sensitive systems of disk structures can be different, but the result is always the same: the need to "repair" inaccessible media.
Destroy your hard drives
There is another way to protect your data. Instead, these hard drives melt or shred. You can pay for demagnetization magnetic hard disks - thus, the magnetic field is destroyed and, therefore, all data. Or you can destroy them with a hammer to save money.
This decision should not be a habit, as it is a waste of still usable equipment. On the other hand, if you have a company and want to exchange hard drives with customer data, it is better to destroy them, and not risk falling into the wrong hands.
Recovering disks with an inaccessible partition table
So, relatively small damage can lead to big trouble, and the storage device will be completely inaccessible. However, despite all the troubles, the situation may be resolved in your favor. If the Master Boot Record or GUID partition tables on your hard disk are only partially damaged (or erased), the rest of the data remains safe in its original places. Provided that there are no other damages, using the right technique and using the right tools, you can hope for full recovery data with almost 100% success.
Receiving a part of the system from the error diagnosis notification does not mean that the disk has already worked. Complete failure may occur in a few minutes, both within a month or a year. But in any case, this means that you can no longer trust your data to such a drive. It is necessary to ensure the preservation of your data, create a backup copy or transfer files to another way of storing information. At the same time, with the safety of your data, you must take measures to change the hard drive.
However, this technology gives you an edge by warning of an imminent disk failure. In case of an error, it is recommended to immediately create a copy of important data, since the disk may fail at any time. But there are errors that no longer allow you to copy data. By default, the user will be prompted to use the File Recovery Wizard. By clicking the “Next” button, the program will prompt you to select the drive from which you will need to restore the files. After the scanning process is completed, you will be offered files for recovery. Select needed files and click the "Restore" button. Select one of the suggested file save modes. Do not save the recovered files to the failed disk.
- Download the program, install it and run it.
- Double click on damaged disk and select the type of analysis you want.
- We select “Full scan” and wait until the disk scanning process is completed.
The right approach
Before moving on to choosing a recovery tool, make sure that you have learned the basic principle of successful recovery. After all, the right approach in this matter is no less important than the use of the right tool. If you start to rush and try to “restore” the disk by formatting it and re-partitioning it, you will only complicate your task. Do not format the disk or redistribute it! Do not burn anything new to disk! Just leave it alone until you install the partition recovery tool, read the manual, and make sure you understand how to use it correctly.
As a result of scanning, detected disk errors can be fixed. This error can be resolved by improving the ventilation of the computer. First, check if your computer is equipped with adequate ventilation, and if all the fans are working properly. Select the drive you want to optimize and click Optimize.
The type of hard drive depends on the style of work on your computer, as well as on what purpose it is used. Please note when purchasing new disc. Each type has its advantages and disadvantages, which are not critical for some users and very important for others. The main ones are the speed of reading and writing data, the volume and tolerance of several records. The disk size is determined in accordance with the installation location of a particular computer or laptop. Interface. Power; Read and write speed; The size of the buffer or cache memory; Response period; resistance to damage.
- The size.
- The two main factors of disk shape are: 3.5 inches and 2.5 inches.
Partition Recovery Tools
Partition recovery: creating a virtual disk image
If your drive contains really valuable data and the media is badly damaged, for a safer recovery, you can back up the entire hard disk by creating a virtual disk image. The simplest partition recovery tools, alas, do not support this feature. Other, more advanced programs may even use a virtual disk image to further restore your data instead of the physical device itself.
So, if the disk contains a lot of valuable information, making a backup before starting the recovery process is a highly recommended step. However, if you are going to restore a disk whose contents are not of special value to you and can be easily replaced (for example, you restore a system hard drive without any documents, photo albums or other information that is difficult or impossible to recreate), then you can save by saving several hours of time by performing recovery directly from the physical disk.
Data recovery
The ultimate goal of recovering partitions is to restore all the data they contain. Therefore, do not try to repair a broken partition table if you are not completely sure of the safety of valuable data. Risk failed recovery and additional data corruption instead of saving it is too large.
To safely and efficiently recover data, use RS Partition Recovery. Run the recovery wizard and select the Deep Analysis mode. In the wizard’s request to select a disk partition or physical device for recovery, select the “ physical device", And then directly the hard drive itself, containing the damaged partition table.
The program will begin a detailed, continuous scan of the media. In order to identify the exact partition configuration of your hard drive, RS Partition Recovery uses heuristic methods and Content-Aware analysis. The tool searches for partitions by scanning the entire disk and trying to detect certain characteristic file signatures supported by the file system. RS Partition Recovery supports all file windows systems (FAT and NTFS), ensuring that all partitions formatted in these file systemswill be successfully recognized and restored.
After detecting the volumes, RS Partition Recovery will display them in the results window, which allows you to extract any information (files and folders) from each volume. The wizard prompts you to select a location to save the recovered files and folders. Make sure it has enough free space to save all files.
Partition Recovery
Repair of damaged or missing partition tables can be performed using a tool that is publicly available - TestDisk. Unlike RS Partition Recovery, this tool requires some additional knowledge and a good understanding of what you are doing and why. In short, the tool can be used to analyze the disk and try to recreate the original partition table.
Why then use RS Partition Recovery? Why not use TestDisk as the main tool to recover data from damaged media.
The fact is that these partition recovery tools perform completely different functions. RS Partition Recovery restores the valuable information contained in files and folders, in documents and photographs. If other actions and recovery procedures fail, using RS Partition Recovery you can always get a copy of all the valuable information. You simply save it on another (healthy) medium, and in this way you will achieve your main goal in a couple of hours.
TestDisk, by contrast, does not work with any files on the disk. Instead, he tries to fix the original partition table, restore the missing partitions, boot sectors and file tables from backups on the original disc. That is, the purpose of this tool is to restore the normal operation of the system as a whole. If he does not succeed, then such tools, alas, will not help in your situation. However, even if TestDisk has failed to restore the original partition structure of your disk, you can always try
