Bit-level (or bit-stream) copying captures every bit on the storage media, including files, deleted files, slack space (unused space within a cluster), and unallocated space. This ensures all digital evidence, including artifacts not visible at the OS level, is preserved for analysis.

Copying at the OS level captures only allocated files visible in the file system, missing deleted files and slack space.

Bit-level copying is a cornerstone of forensic best practices as specified in NIST SP 800-86 and SWGDE guidelines.

Timestamp changes and unnecessary information issues are secondary concerns compared to the completeness of evidence.

Comprehensive and Detailed Explanation From Exact Extract:

The foremost principle in digital forensics isnever altering the original evidence. This ensures integrity, authenticity, and admissibility in court.

Investigators analyze forensic copies, not originals.

Write-blockers and hashing are used to prevent changes.

Any alteration—intentional or accidental—can invalidate evidence.
