A digital forensics team is reviewing suspicious objects on a hard drive. Which approach best preserves the original state of those objects while allowing deeper investigation?
Rely on the system’s own diagnostics for analysis
Use a dedicated setup with a disk image for investigation
Mount the drive on an active device for initial review
Lock the volume on a shared staging platform and scan it
Investigators use disk imaging to preserve the original data without risking unintended changes. By working from a forensic image in a dedicated setup, they maintain the integrity of timestamps and file structures. In contrast, using live system tools or mounting the drive on active machines can overwrite metadata or contaminate evidence, making the findings unreliable in legal or forensic contexts.
