Explanation

E01 (EnCase Evidence Format) and S01 (Smart Image Format) are both forensic container formats specifically designed for digital investigations - they embed hash values (typically MD5 and/or SHA1) directly within the image file, enabling automated integrity verification and supporting chain of custody requirements.

The distractors fall short because: ISO is a raw optical disc image that contains no embedded metadata or hash; CUE is merely a text-based cue sheet describing track layout for disc images, holding no hash data whatsoever; and 001 (dd) is a raw bit-for-bit split segment with zero embedded metadata - any hashing of dd images must be done externally and stored separately.

Memory tip: Associate E01 and S01 with "Evidence Security" - both are purpose-built forensic formats that bake in hash verification by design, whereas ISO, CUE, and dd are generic or raw formats with no built-in integrity guarantees.
