            <p>The discipline of computer forensics demands a rigorous, methodical approach to the identification, preservation, and analysis of digital evidence. As technology becomes increasingly embedded in daily life, the ability to extract and interpret data from digital storage devices is paramount for legal, corporate, and incident-response investigations. This course, Computer Forensics: Disk Imaging, File Systems, and Metadata Analysis, provides a comprehensive exploration of the technical and procedural frameworks required to conduct defensible digital investigations. By establishing a strong foundation in evidence handling and chain-of-custody protocols, investigators can ensure that their findings remain reliable, repeatable, and legally sound throughout the lifecycle of an examination.</p>

<p>Throughout this program, participants will systematically navigate the core phases of a forensic examination. The curriculum begins with the critical processes of forensic disk imaging, emphasizing the use of write blockers, cryptographic hashing, and image verification to preserve original evidence without alteration. Subsequent modules delve into the underlying architecture of common file systems, such as NTFS, FAT32, and APFS, equipping learners with the knowledge to analyze partitions, volumes, and unallocated space. Furthermore, the course addresses the mechanics of deleted file recovery and file carving, culminating in a detailed examination of file metadata, timestamps, and system artifacts. By synthesizing these technical skills with objective reporting practices, participants will be prepared to reconstruct user activities, establish accurate timelines, and communicate their investigative conclusions with precision and clarity.</p>
