To verify a new forensic tool by viewing a disk's data in its unprocessed form, which type of tool is appropriate?

• A. Disk editor
• B. Hex editor
• C. Data recovery tool
• D. Disk imager

Answer: (A)

Viewing data in its unprocessed form means seeing bytes exactly as stored, without file system interpretation. A disk editor is designed to read and display the disk at the level of sectors and raw bytes, preserving the physical layout and allowing you to inspect each sector. This makes it ideal for verifying a new forensic tool's behavior, because you can compare the tool’s output to the exact data on disk. While a hex editor also shows raw bytes, the disk editor provides a disk-aware view with sector-by-sector navigation, which more closely reflects how forensic tools access disk content. A data recovery tool focuses on recovering files by interpreting file system structures, so it introduces interpretation rather than presenting raw data. A disk image utility copies the entire disk bit-for-bit but doesn’t give you an ongoing, direct view of unprocessed data. Therefore, the disk editor is the most appropriate choice for viewing a disk’s unprocessed data.
