What does creating an image file from a suspect's disk drive accomplish in forensics?

Creating an image file from a suspect's disk drive is a crucial step in digital forensics because it allows investigators to analyze the data contained on the drive without altering the original evidence. This practice preserves the integrity of the original disk, ensuring that it remains in its untouched state throughout the investigation. By working with a bit-for-bit copy of the disk, forensics professionals can explore file system structures, recover deleted files, and conduct a thorough analysis of the data without the risk of changing or damaging the original evidence. This is essential for maintaining the validity of the findings in court, as any modifications to the original data could lead to questions about the reliability of the evidence. Thus, creating an image file is a standard procedure designed to protect the authenticity of the evidence while facilitating in-depth forensic analysis.
