What We Say About Forensic Data Recovery Will Come In Handy

As you can easily find, a large quantity of data recovery software appeared on the market during past few decades. This indicates the increasing needs for and importance of data recovery. Why do we need to perform data recovery? How can we finish this process easily? Questions like those are asked by people in all walks of life.

Well, what is data recovery exactly? As a matter of fact, in computing, data recovery refers to the process of rescuing inaccessible data from corrupted/damaged/formatted/wiped/dead drives, such as internal hard drive and removable USB device.

Each time when you find the data stored in certain place cannot be accessed as usual, you should firstly think of recovering data, rather than performing operations to try to fix it (unless you’re pretty sure that what you’re doing will solve the problem and bring back your data).

Yet, the difficulty lies in that most of the data recovery software on current market is only suitable for home use and small-scale use. That is to say, most software is not perfect enough for special occasions, including forensic data recovery, patient records restore and the recovery of many other high confidential files you can find in the nation.


After taking those factors into consideration, we highly recommend users should choose MiniTool Power Data Recovery to complete digital evidence recovery since it provides high security and simple operations.

It is no exaggeration to say that MiniTool Power Data Recovery could be the best forensic HDD recovery software; its enterprise license and technician license are ideal for data forensics.

Forensic Data Recovery Analysis

With the rapid development of computer & network, we can easily find out the fact – computer crimes and civil disputes by taking advantage of network are increasing in recent years. In this context, electronic evidence (digital evidence) obtained by electronic forensic starts to step into judicial authentication filed.

Electronic evidence recovery, like deleted data recovery and formatted data recovery, becomes a powerful and commonly used means of evidence collection adopted in forensics.


To put it in a simple way, after the digital evidence acquired by electronic forensic during judicial identification was deleted accidentally or formatted mistakenly, we’re now able to get it back by using relevant techniques and tools. In this way, under the proper operations of electronic forensic, reliable evidence can be found to justice criminals through judicial identification.

According to statistics, the work efficiency of electronic forensic teams equipped with high-tech data recovery tools is greatly improved. And a large quantity of crime cases is settled by virtue of forensic data recovery.

About Network Forensics

Network forensics refers to the actions of capturing, recording and analyzing network events, so as to find out the source of security attacks or other issues. This term is introduced by firewall expert Marcus Ranum from the field of criminology and law.

In the view of Simson Garfinkel, an expert specializing in computer forensics and computer privacy issues, network forensics system contains the following two types:

toTo capture as much as possible” system: in this system, all the packets are captured through certain node and the analyzing results will be written into memory in accordance with the batch mode. A lot of storage space is required in this system, so RAID is often adopted.

raid This will show you all things about RAID data recovery.

toStop, look and listen” system: in this system, each packet each packet goes through fundamental analysis so as to leave some basic information for future analysis. The need for storage space in this system is relatively small, but a fast processor is required to keep up with the input stream.

Note:
  • Accidental deletion of old data is required in both systems to make room for new data.

  • Network forensics product is sometimes also called Network Forensic Analysis Tool (NFAT).

  • Computer forensic analyst now becomes a popular and respected career.

Background of Digital Forensics

Since many of today’s crimes are provided with characteristics like high-tech and intelligence, the electronic evidence gained in judicial identification is playing an increasingly important role. That is to say, people pay more and more attention to cyber forensics and mobile forensics. And meanwhile, forensic investigation is made popular to the public.

Yet, the digital evidence is intangible, easy-to-damage and unsafe, so it can be easily deleted or formatted. Precisely because of this, deleted data recovery and formatted data recovery technology become extremely important and also form the primary means of judicial expertise.

As a result, a lot of manpower and resources are devoted by law enforcement agencies to enhance the ability to recover deleted and formatted digital evidence. Thus, an outstanding electronic forensic team is formed and proved to play a key role in tracking down the criminals (in fact, this team has found much significant evidence in various judicial identification cases).

“The forensic acquisition in full or in part of data stored on non-functioning storage media through the use of sophisticated equipment and techniques for the purpose of presenting the data in a legal forum.”
-- said by Todd G. Shipley


As you can see, the forensic data recovery draws the attention of an increasing number of people. Therefore, when selecting the forensic HDD recovery software for recovering electronic evidence, users should focus on high security and confidentiality.

MiniTool Power Data Recovery owns a large number of users and most of them think it is the best recovery software they’ve ever used. It owns high security but requires easy operations, so it’s a wonderful choice for the recovery of digital evidence. And we suggest users to get Enterprise License or Technician License now for recovering digital evidence.

In addition to high security, Power Data Recovery also provides excellent compatibility, so it can support almost all file systems, file types and storage devices. Hence, no matter you want to restore data from just internal hard drive or recover data from NAS HDD, it can be served as a wonderful assistant.

Principle of Data Recovery


In reality, lots of people do not know deleted/formatted data (or data lost due to other operations like virus attack) can actually be recovered; they think once the data are deleted/formatted, they’ll be gone for good. However, that’s not the case. Now, we’d like to show you the reason why we can get back missing data.


When a file is saving to hard disk, the following information will be recorded to DIR area at first: file name, file size, file modification date (the location of file is not included). After that, the real content will be saved to certain place of DATA area. And at this time, the location of file will finally be recorded in DIR area.

When a file is deleting somehow, the first character of certain file in DIR area will be replaced by E5 (conventional deletion). That is to say, the real content is still intact unless new file is written in to use the place which is originally occupied by deleted file.

Likewise, when files are lost due to drive formatting, it is only the relevant information that has been removed, not the real content.


Therefore, in order to avoid secondary damage, which will result in permanent data loss, we suggest users to stop using the drive with deleted/formatted data immediately and choose reliable recovery methods to regain as much data as possible.

How to Prevent Data Loss

To be honest, data loss in today’s era is hard to avoid. This can be reflected by the prosperity of data recovery software. Yet, though forensic data recovery could be achieved with powerful software, we still need to do our best to prevent data from being lost suddenly. Here are some useful data prevention measures.

Forensic data recovery 10

how to prevent data loss 1 Never save your data files to the same drive in which operating system (OS) is installed

As we all know, most of the text processors will save the file you created to the documents library in computer. But, this is precisely the most unsuitable place for file storage since it is on system drive. When the OS is crashed due to virus attack or other soft failures, you have to reformat the drive to repair/reinstall OS. Thus, new data will be saved here to overwrite the original data.


how to prevent data loss 2 No matter how safe you think the drive is, please backup your data on a regular basis

It’s often not enough to just save your data to computer internal hard drive/removable disk. You need to back up at least your important data to another place and then update the backups regularly. In this way, whenever your original file is lost, you can rely on the backups immediately to avoid any unnecessary losses.


how to prevent data loss 3 Decrease human error as much as possible

We have to admit the fact that data loss is caused by our own improper operations most of the time. One of the most common reasons is mistaken deletion of files. So, we advised users to enable auto save functions in all programs (if there is such function) and be more careful when editing files.


Verdict


With the perfection of legal system society, the legal status of electronic evidence acquired in judicial identification becomes higher and higher. Currently, the deleted data recovery and formatted data recovery are playing a very important role in ensuring the integrity and authenticity of electronic evidence.

So users must confirm they have chosen the reliable and effective software to regain lost digital evidence files when necessary. By writing this article, we hope more people could solve their data loss problems easily without privacy leakage.
