A separate manual validation is recommended for all raw acquisitions at the time of analysis.

• A. True
• B. False
• C. Sometimes
• D. Not specified

Answer: (A)

Independent validation of a forensic image is crucial to ensure data integrity and reproducibility. Having a separate person perform a manual check at the time of analysis provides an independent verification that the acquisition was done correctly, the image is a true, bit-for-bit copy of the source, and the hash values, metadata, and tool configurations align with what was expected. This catch-any-issues step helps detect errors or misconfigurations that automated processes can miss, supports the chain of custody, and makes the evidence more defensible in court or review.

Because these reasons, it’s considered best practice to require a separate manual validation for all raw acquisitions during analysis. Relying on a single pass or delaying validation increases the risk that problems go unnoticed and could undermine integrity or admissibility. The other options imply variability or uncertainty that doesn’t align with standard forensic methods.
