■MASAMUNE Clone Features

●Linux based software running from CD• Physical reproduction of data on external HDD without removing internal HDD* from PC.• Creation of image copy of a RAID system containing several HDDs on one HDD.

*HDD: hard disk drive.*RAID: a disk system achieving high speed and error tolerance through dispersed data recording.

●Common PC as Duplicator•

●Source and Target Confirmation•

●Proprietary algorithm (patent pending) reduces the number of read errors•

*Our proprietary algorithm is submitted for international patent application not only for software duplication but in much more wider area.

●Generates detailed log containing addresses of all unreadable sectors, etc.• Can record addresses and the number of all sectors impossible to read.

Clone Recovery EditionReliable software duplicator, quickly supporting yourwork through data recovery.This is the MASAMUNE Clone Recovery Edition!

Because software is running from CD, it does not require a special system;a common PC on-hand can be used for disk copying.

Can protect from mismatch occurring when it is impossible to confirm the connected device(electronic recording media).

Proprietary algorithm, based on the experience of Data Salvage, implements physical data reproduction with small number of errors using such methods as thorough read/retry to read more sectors.

■Failure Levels brought in for data recovery

●Common HDD failure types:

　・Sorted by the failure occurrence rate　　　　1: read errors　　　　2: firmware failure　　　　3: head damage

*It may be possible to fix read errors using MASAMUNE algorithm.

●Among damaged HDDs processed for data recovery, the most common failure type is the read errors; they comprise more than half of processed HDDs.

【Conclusion】Read Error Eliminating Algorithm implemented inMASAMUNE Clone Recovery Edition is useful!

Using MASAMUNE software, it is possible to clone disks without need to physically open the damagedHDD and perform operations in clean environment with difficulty and risk of head exchange, etc.

Simple failures: file system damage, etc.

Moderate failures: read errors, etc.

Serious failures: damaged head/PCB, etc.

*Statistic based on damaged HDDs processed by our company.
