Data recovery software for cold data recovery equipment for major diseases

Category of Hard Disk faults

Since the birth of computers, data recovery has gradually matured along with the development of computers. In today's information age, data recovery is even more important. Modern data recovery technology can solve data loss problems caused by multiple hard disk faults. To sum up, there are roughly three types of Hard Disk faults that can be restored:

With the development of hard disk technology, data recovery plays an increasingly important role.

I. logic layer faults
Virus intrusion, formatting or partitioning by mistake, cloning by mistake, accidental deletion or overwriting, hacker damage, hard disk logical lock, accidental power failure during operation, electromagnetic interference, and so on May all cause hard disk logic faults. The fault is manifested in the loss of the operating system, failure to start the program normally, disk read/write errors, failure to find the required files, failure to open the file, garbled code after the file is opened, no partition on the hard disk, and prompt for a hard disk partition. no formatting and so on.

Ii. Physical Layer faults
Hard Disk Physical Layer faults are mainly caused by disk scratches, head deformation, magnetic arm breakage, head amplifier damage, chip composition or other components damage. After the hard disk is physically damaged, frequent "click and click" magnetic group impact sound or the motor does not turn, no sound after power-on, the head positioning is not allowed to cause read and write errors, system paralysis or crash blue screen, but the hard disk is re-formatted and then re-installed the system again everything is normal and the system startup time is particularly long.

Iii. Bad Track layer faults
The impact of the hard disk's use environment or improper operations may lead to bad sectors on the hard disk. A hard disk with bad sectors may slow down reading/writing speeds and read the disk repeatedly for a long time, which is prone to errors, or the system prompts "unable to read or write files", and may even lead to blue screen, black screen and other phenomena. Bad track data recovery is also a major difficulty in hard disk data recovery.

Iv. Firmware layer faults
Firmware is the control software that coordinates and controls various components in the hard disk. Generally, users cannot access or modify the software. After each power-on, the hard disk reads the sector where the firmware is located. After a long time, the disk may suffer from magnetic weakening and other issues, resulting in a read error. Common hard disk firmware layer faults include seeking sound, but not recognizing disks, and recognizing manufacturer-only models. At present, firmware layer faults account for 40% of Hard Disk faults, but data recovery based on the firmware layer is the most difficult among several hard disk faults.

Principles of data recovery

To improve the data recovery success rate, you must first understand the principles of data recovery, and then select an appropriate data recovery tool based on the causes of hard disk failure. For data loss caused by logical layer faults and some physical layer faults of hard disks, the data does not actually disappear from the disk, the system records the data storage location in the hard disk file list as blank. If the data is not written to this area, the data is stored in the original location. In addition, the partition is lost, hard disk formatting, and data is not deleted. The partition information can be recovered through data recovery.
For most physical layer faults, bad track layer faults, and firmware layer faults of the hard disk, the data recovery principle is different. Most physical layer faults of hard disks need to be replaced with damaged accessories. After the hard disk is repaired, hard disk data is extracted. For bad track layer faults, you can use the commands of the hard disk data recovery tool to skip the severe areas of Hard Disk Bad Sectors, obtain most of the data on the hard disk. For firmware layer faults, you can recover data by writing the firmware back or using the virtual firmware area.

The well-known data recovery software EasyRecovery and R-studio have developed and improved over the past 10 years.

How to select a data recovery tool

Data Recovery tools can be divided into two types: data recovery software and data recovery software hardware integrated equipment. The data recovery software is technically inadequate and has very limited data recovery capabilities. It can be used as a broad spectrum medicine to cure colds, currently, data Recovery software is widely used, including Easy Recovery, R-Studio, and Final data. When selecting data Recovery software, you must check the history, the two data recovery software recommended above has been developing for nearly ten years, and its functions and stability are trustworthy. The hardware-integrated data recovery software equipment is mainly used to recover data from faults at the physical layer, firmware layer, and bad track layer. It can be compared to the treatment of surgery and complex diseases. Global Data recovery software and hardware integration equipment manufacturers are only a few of China's efficiency sources (Salvation Data) and Russia's ACE, RT and so on.

The two types of data recovery tools have different levels of Hard Disk faults. The data recovery software can only solve data loss problems caused by hard disk logic layer faults. The data recovery software scans all the sectors to change the storage status of data in the file list, or finds all the boot sectors by scanning. This is defined as a result, and finds the lost partitions. Using data recovery software for data recovery does not have high technical requirements for the operator and can achieve immediate results for simple data recovery problems. However, when using data recovery software, pay special attention to avoid secondary damage to the source disk. If the data recovery software encounters a bad hard drive, it will be stuck. If it is read multiple times, it is easy to scratch the disk. In addition, the data recovery software may run to write data, undermining the original data of the source disk.

With the development of hard disks to large capacity, 320 GB and GB hard disks have become mainstream configurations, and even TB-level hard disks have been widely used. The high-capacity hard drive speed is getting faster and faster, and the hard drive temperature is getting higher and higher, which increases the hard drive failure.

The most effective data recovery tool for Hard Disk Physical faults and firmware faults is the hardware integrated equipment for data recovery software. Data recovery software hardware integration equipment is applicable to all hard disk faults. It can recover data not only from physical faults and firmware faults, but also handle hard disk logic layer faults, is a necessary data recovery tool for data recovery service providers. If the data recovery software is a small clinic on the street, the hardware integrated equipment of the data recovery software is a comprehensive big hospital. Of course, you must be familiar with the hardware integrated equipment of data recovery software and have high technical and experience requirements for data recovery engineers, therefore, it is important for users to provide after-sales service and technical support for data recovery software and hardware integration equipment manufacturers.

Of course, the main users of data recovery software and hardware integration equipment are professional-level data recovery companies and internal data recovery centers of enterprises and institutions, you can download the data recovery software from Alibaba Cloud for the loss of the logical layer. If a fault cannot be solved, it is recommended that you find a professional data recovery company to complete the service. Here, we remind all professional data recovery companies in China that they have licensed genuine equipment and software for the effective rate source, none of these items are generally the same as any of the three non-qualified clinics, so you must choose them with caution for your data security.

Summary: data recovery software and hardware integration equipment have their own advantages, but the focus is different. Before data recovery, you must first confirm the cause of data loss, find the cause of hard disk failure and select the appropriate data recovery tool for data recovery to achieve twice the result with half the effort
