How to Make a Forensic Copy of a Hard Drive (the Quick and Easy Way)

A forensic copy might sound like a completely different process, but it's just a bit-for-bit or sector-by-sector clone of electronic media such as a hard disk. A forensic copy is used as digital evidence in an investigation so that the data can be used in court or by a company. In this article, we'll learn what it is and how to make a forensic copy of a hard drive with professional cloning software.

What is a forensic copy of a hard drive and what are its benefits? A forensic copy of a hard drive refers to an exact and complete duplication of the original hard disk drive for legal, investigative, or forensic purposes. This copy preserves the integrity of the original data, ensuring that no tampering or alteration occurs, making it highly credible in legal proceedings. The benefits of a forensic copy include: 1. Preservation of original evidence: By creating a copy, the original hard drive can be safely stored, preventing loss or damage to the evidence due to improper handling. 2. Data security: A forensic copy ensures that sensitive information remains secure during analysis, as only authorized professionals have access to it. 3. Repeatability: Multiple copies can be made for further analysis or review by different agencies without affecting the original data. 4. Legal compliance: In legal proceedings, using a forensic copy as evidence meets strict requirements for evidence preservation, ensuring fairness in the judicial process. 5. Analysis efficiency: Analyzing multiple copies simultaneously can speed up case processing and enhance work efficiency. 6. Avoiding chain of custody issues: By working with forensic copies, the collection and preservation of evidence are not interrupted or compromised when handling the original hard drive. 7. Record integrity: The forensic copying process often records details such as the time, method, and other relevant information, which helps validate the legitimacy and reliability of the copy. In summary, creating a forensic copy of a hard drive is an essential step to ensure the accuracy of evidence, protect privacy, and adhere to legal procedures.

Electronic devices have become an indispensable part of our lives, and everything is digital. Often, the data stored on them is critical for company and legal investigations. That's when we make a forensic copy or image for examination. So, what sets a forensic copy apart from a regular clone?

Since a forensic image is a bit-for-bit clone, we create a copy of the source drive by creating a bitstream that doesn't alter any bits. More importantly, it can replicate deleted data, including files in free space and swap data. A forensic image also offers these advantages:

How to Create a Forensic Copy/Imaging of a Hard Drive

Here are two ways to create a forensic copy or image of a hard drive:

There are two ways to create a forensic copy/image. While both help in creating a duplicate, the main difference lies in how we store them and the space required. Let's delve into them in detail.

Method 1: Disk to disk: An exact clone

As the name implies, this option copies the entire disk to another disk. All data is transferred from one disk to another, and if the target disk is larger, the extra space is filled with zeros.

Method 2: Create an image of the disk to a file

This method transfers data to another drive sector-by-sector, creating an image file. The image can be stored in one of two formats: DD (RAW) or EnCase (E01).

DD (Raw Data): A DD image saves the file to the target drive in a format similar to the source drive. This method takes up as much space as is available on the hard drive, even if it's not needed. As a result, investigators or forensics experts must purchase larger hard drives, at additional cost.

EnCase (E01): When storing file data, EnCase compresses it to save disk space. Typically, this reduces the size of files to about one-ninth of their original size. Also, EnCase images are the best way to preserve data integrity. It achieves data integrity by creating a hash value, which means that for every 64KB block of data, a hash is created and used to encrypt the next file. This process continues until the last file. With this form of data hashing, you can verify the integrity of the files and whether any changes have been made to them. If you find any compromises, you can locate the original data using the encryption and remove it from the investigation.

Now, you know what's better, Encase Image uses data compression to save space and ensure data integrity. A good example of this is how many companies offer zip files for you to download, which you can then decompress to your local drive, thus protecting the code and the data from interference.

Frequently Asked Questions

How can a forensic image be created if the drive cannot be removed?

If you don't want to remove the hard drive to create a forensic image, you can choose to clone the hard drive with a bootable USB or another hard drive. This way, you can transfer or clone the entire content of the hard drive to a new one and boot it on another computer to access the files.

2) Can a damaged hard disk be cloned?

Yes, you can clone a failed hard drive. Before giving up on it, you can recover its contents by using a professional disk cloning tool. The Disk Copy utility allows you to create a clone of the hard drive even when the system won't boot.

What is the difference between a forensic copy and a forensic image? A forensic copy and a forensic image are both methods used to duplicate original evidence data in digital forensics, but they have some key differences: 1. **Integrity**: A forensic image is an exact byte-for-byte replica of the original storage medium, such as a hard drive, USB drive, or mobile device memory. It is typically created using specialized tools like EnCase or FTK Imager to ensure the integrity and consistency of the data. The image includes boot sectors, file systems, unallocated space, and all hidden or encrypted data, preventing tampering or loss during the duplication process. 2. **Readability**: A forensic copy refers to copying files and folders directly from the source device to another location, like another hard drive or storage device. This is often done using standard file copying utilities and may not include all the data present on the original device, especially unallocated space. As a result, a forensic copy might be less comprehensive than a forensic image and may not provide the same level of evidentiary preservation. 3. **Purpose**: Forensic images are primarily used to ensure that the original evidence remains untouched during analysis and examination. Due to their integrity and immutability, forensic images are generally considered admissible in court. A forensic copy might be more suitable for quick data retrieval and previewing but may not suffice for in-depth analysis or legal proceedings. 4. **Storage Requirements**: A forensic image usually requires storage space equal to or larger than the original device, as it contains all the data. In contrast, a forensic copy might only replicate visible or allocated data, requiring less storage space. In digital forensics, forensic imaging is the preferred method due to its higher level of evidence protection and assurance of integrity.

A forensic copy is a duplication of the source drive's contents to a target drive, preserving data integrity but not necessarily the data itself. A forensic image is a comprehensive snapshot that captures everything on the source drive, including deleted files. Because of this feature, images are preferred in forensic investigations.
