Data Recovery and the Art of Computer Forensics


In today’s technology-driven world, the digital footprint we leave behind is vast and intricate. Our lives, both personal and professional, are intricately woven into the digital realm. From cherished memories to crucial business data, our electronic devices store a treasure trove of information. However, what happens when this treasure becomes lost or inaccessible? That’s where the digital sleuths of computer forensics and dat recovery come into play, unearthing lost data and messages from mobile phones and computers. In this blog, we’ll explore the fascinating world of computer forensics, focusing on the intricate process of data recovery, particularly for lost messages on mobile phones.


Understanding Data Recovery


Computer forensics and data recovery is the field of study that deals with the preservation, identification, extraction, and documentation of digital evidence. This evidence can range from retrieving lost files to investigating cybercrimes. It’s a meticulous and highly specialized field that involves the application of computer science and investigative techniques to collect, analyze, and preserve electronic data.

One of the key areas of computer forensics is data recovery. This process involves retrieving information from damaged or inaccessible storage media, often in situations where the data loss was accidental. Data recovery is crucial for a wide range of scenarios, such as accidental deletion, hardware failure, and, in the context of our focus, the recovery of lost messages on mobile phones.


The Challenge of Data Recovery


Data recovery is akin to piecing together a digital jigsaw puzzle. It’s not just about finding the missing pieces; it’s about understanding how they fit together. When it comes to mobile phones, the challenges are manifold. Messages, including text messages, multimedia messages, and chat history, are often stored in complex, encrypted databases. When a message is deleted, it isn’t always permanently removed. Instead, it’s marked as available space for new data, allowing the possibility of recovery.

Recovering lost messages involves using specialized tools and techniques to access these databases and retrieve the data before it’s overwritten or lost forever. This process can be quite intricate, requiring a deep understanding of the specific mobile operating systems and their security measures.


Data Recovery Tools and Techniques


  1. Software Solutions: There are numerous software tools available that claim to recover lost data from cell phones. These tools often work by scanning the device’s storage for traces of deleted data. While they can be effective for simple cases, they have limitations and might not work in more complex scenarios, such as encrypted or overwritten data.
  2. Forensic Hardware: In more complicated cases, computer forensic experts use specialized hardware to access a cell phone’s memory directly. This allows them to bypass security measures and extract data, including lost messages. However, this approach requires a high level of technical expertise and can be costly.
  3. Forensic Imaging: Creating a forensic image of the device is a common practice in data recovery. This is a bit-by-bit copy of the device’s storage, preserving all data, including deleted messages. These images can then be analyzed in a controlled environment, ensuring the data remains unaltered.
  4. Database Analysis: Recovering lost messages often involves delving into the database structures of messaging apps. Experts must understand the intricacies of these databases, their encryption methods, and the specific data storage formats.
  5. Overcoming Encryption: Many modern cell phones employ strong encryption methods to protect user data. Experts in computer forensics must possess the skills and knowledge to overcome these encryption barriers.


Issues in Data Recovery


The process of recovering lost messages is not without its issues:

  1. Data Overwriting: Deleted messages can be quickly overwritten by new data, reducing the chances of successful recovery. Time is often of the essence in data recovery.
  2. Encryption: As mentioned earlier, modern devices use encryption to safeguard data. Breaking through encryption is a complex and legally sensitive process.
  3. Hardware Issues: Physical damage to the device can further complicate the data recovery process. In some cases, hardware repair may be necessary.
  4. Data Fragmentation: Recovering messages from fragmented data is akin to piecing together a shattered vase. It’s challenging, but not impossible for experts.
  5. Legal and Ethical Considerations: Data recovery may involve handling sensitive information, and it’s crucial to navigate legal and ethical concerns, especially in cases involving privacy and criminal investigations.


The Importance of Data Recovery


Data recovery is not just about the retrieval of lost messages for personal use; it plays a crucial role in various sectors:

  1. Business Continuity: For businesses, data loss can be financially devastating. Recovering critical data, including messages and communications, is essential for ensuring continuity and preventing significant losses.
  2. Legal Investigations: In criminal and civil investigations, recovering messages and digital evidence is often vital for building cases and uncovering the truth.
  3. Personal Memories: On a more personal note, recovering lost messages can help preserve cherished memories and sentimental communications.


What Are The Costs of Data Recovery??


Unfortunately, there is no shopping list of costs available for this type of work. Data recovery is a science, and each device we look at is different so the techniques differ to recovery data in each scenario. This is why cost can be hard to predict.


In the first instance we usually need to have the device with our technician so that he can look it over and analyse what he is dealing with.  We do need to charge an appraisal fee for the time spent on this. As a guideline this appraisal fee is $350+GST


Once the technician understands the particular device and has analysed what might be achievable, he is in a better position to advise what might be able to be done.


For mobile phones:

Depending on the phones issues it is carefully disassembled and examined to distinguish any physical or electrical damage. After this, preliminary tests are performed to examine the viability of a successful recovery. This is part of the diagnostic that costs $350+GST.


For data recovery relating to a computer

Depending on the laptops issues it is carefully disassembled and examined to distinguish any physical or electrical damage. After this, preliminary tests are performed to examine the viability of a successful recovery. This is part of the diagnostic that costs $350+GST.

After this, the real cost will come down to how many hours of work might be involved. This is where it is just not possible to predict without the diagnosis process described above.



In the digital age, our lives are intertwined with the data we generate and store on our devices. When this data becomes inaccessible or lost, computer forensics professionals step in as digital detectives, using their expertise to recover messages and other valuable information. The challenges are substantial, but so are the rewards, whether it’s protecting a business from financial ruin, aiding in a legal investigation, or simply preserving treasured memories. The art of data recovery is a testament to the ever-evolving world of technology and the dedication of experts to unlock its secrets.
