The MASAMUNE Clone Forensic Edition is a Linux-based software that runs from a CD to create physical copies of data from external hard drives or other electronic media without removing the internal drive from a computer. It can copy data at speeds up to 42GB per minute and has algorithms that reduce read errors by storing and retrying reads of skipped or unreadable sectors. The software also generates an encrypted log and hash values to verify the integrity and identity of copied data.

1. ■Evidence Preservation Tool MASAMUNE Clone Forensic Edition Features
●Linux based software running from CD
・Physical reproduction of data on external HDD without removing internal HDD* from PC.
・Can support all interfaces and create physical copies of
various electronic recording media.
*HDD: hard disk drive.
●Depending on combination of hardware and cables being used,
high speed of 42 GB/min (actual measured value) can be achieved.
●Proprietary Algorithm (patent pending) reduces the number of read errors
・Can create highly accurate clone disks by storing addresses of skipped bad sectors
and unreadable regions and repeating read operations on them.
●Can generate electronic signature using content of the log which is encrypted
using proprietary algorithm and detects unauthorized log alteration.
●Identity verification using hash value
・Can verify identity of data using hash value calculated by hash function.
●Source and Target confirmation
・Can protect from misoperations and accidental original overwriting by confirming the
connected device (electronic recording media).
Clone Forensic Edition
■MASAMUNE Clone Forensic Edition Algorithm
・Avoids retry operation on sector where read error occurs using proprietary algorithm.
1）Skip Operation (Normal Copy Mode).
Avoids read error by skipping sectors in the order of their occurrence.
2）Detailed repeated reading of the skipped sectors (Final Copy Mode).
Reliable physical reproducing of the skipped sectors.
Reliable software duplicator quickly supporting
your work through preservation of evidence for
digital forensic investigation.
This is the MASAMUNE Clone Forensic Edition!

2. ■What functions are required in an evidence preservation tool?
●Complete (physical) reproduction
・Processing of bad sectors (do not skip / terminate with errors).
・Avoidance / reduction of read errors.
●Identity verification
・Data identity verification using hash value calculated by hash function and binary comparison of bit strings from
copy source and target.
(According to the 3rd edition of the IDF evidence preservation guidelines)
●Working log generation
・Detailed information about damaged and recovered data.
・Work results including work content, addresses of unreadable sectors, etc.
・Detect unauthorized log alteration.
【Application examples】
MASAMUNE Clone Forensic Edition can be used in the following cases.
1) Copying contents of the disks of a notebook PC which is hard to dismantle.
Physical reproduction of data on external HDD without removing internal HDD/SDD from a slim notebook PC.
2) Copying contents of the disks of a server PC.
Image copies of disks from Unix certified servers and RAID arrays can be created.
3) Copying contents of an unstable HDD.
4) Field works with minimal equipment.
Because software is running from CD, it does not require a special system; a common PC on-hand can be used for
disk copying.
*Please read the user manual before using MASAMUNE Clone software.
*Depending on media condition creation of Clone may be impossible.
*Specifications and design of MASAMUNE products may be modified for improvement without prior notice.
■Recommended System
*USB port is necessary for USB dongle based license key.
(Even if the below conditions are met software may not work due to specific hardware configurations)
Even if OS working from such HDD terminates with errors or usual disk copy operation is difficult, it is possible to
create highly accurate physical copy of such HDD by adding command line parameters and adjusting settings.
