CST VerdictBased on our analysis of available product data, here is our conclusion:
Forensic investigators and incident responders who need fast, reliable disk imaging on legacy systems should consider Bmaptool for its efficiency in block-mapped copying, which significantly reduces imaging time compared to sector-by-sector alternatives. The tool's 241 GitHub stars reflect sustained practitioner trust despite its discontinued status, particularly among analysts working with older hardware where modern imaging tools introduce unnecessary overhead. Skip this if you're building a managed forensics workflow requiring vendor support or integration with commercial case management platforms; Bmaptool is a standalone utility for investigators who know exactly what they're doing.
Forensic investigators and incident responders handling seized Apple devices need DMG2IMG to convert proprietary DMG archives into mountable HFS+ images without proprietary tools; the tool supports all three major compression formats (zlib, bzip2, LZFSE) and costs nothing, making it indispensable for chain-of-custody workflows. With 255 GitHub stars and active maintenance, it's proven in real investigations where you can't wait for commercial licensing. Skip this if your team exclusively uses commercial forensic suites like Cellebrite or Axiom that handle DMG conversion natively; DMG2IMG shines when you need a standalone, auditable converter that doesn't lock you into a vendor ecosystem.
