Accurate copies data so that it’s an exact match to the original data

A hard drive duplicator is designed especially for forensic identification, equipped with write-block function and calculation of MD5 and SHA-1 hash value. It also provides an operation records so it is easy to review the record of all the hard drive copies.

What is forensic duplication

A Forensic Duplicate is a file that contains every bit of information from the source in a raw bit stream format.

Calculation of MD5 and SHA-1 Hash Values

Forensic data copy must be legally identical to the original. Holmes 221B hard drive duplicator has the verification function after copying is completed. The hash value is calculated by using MD5 and SHA-1. Just use the Holmes 221B hard drive duplicator to calculate the unique hash value of the original hard drive in advance, and compare it with the copied hard drive hash value to determine whether the copy matches the original hard drive.

Source write blocker

Holmes 221B works as a hardware Write Blocker when source hard drive is connected to a computer through USB 3.0 port. It can intercept and prevent (or ‘block’) any modifying command operation from ever reaching the source hard drive. No data will be changed when you read the source hard drive from a computer.

HPA/DCO duplication and removal

Besides data duplication, Holmes 221B also supports HPA (Host Protected Area)& DCO (Device configuration overlay) duplication and removal. It makes sure you have an identical hard drive as the original.

Record of Hard Drive Operation

You can check the complete hard drive operation record through Holmes 221B hard drive duplicator, including the time of copying, number of copies, when and what kind of function operated , without worrying about the information being tampered with!

Outstanding Copy Speed Up to 300MB/s

The copy speed of Forensic Holmes221B HDD Duplicator is up to 300MB/s or 18GB/m. The high copy speed will remain the same even if the number of load is increased. Stable transmission speed increases your working efficiency and productivity!

Eight Data Erase Modes Keep from the Leakage of Confidential Data

When manufacturers/maintenance and repair shops need to reuse hard drives, this is an ideal function to erase data based on different level of secrecy.

Quick Erase

Erase the index of a hard drive within a few seconds.

Full erase

Erase the data from a hard drive by overwriting each sector which is able to read/write data.

3-Pass DoD

Erase HDD 3 times complying with the 5220.22-M data erase security standard of the U.S. Department of Defense.

7-Pass DoD

Erase HDD 7 times complying with the 5220.22-M ECE data erase security standard of the U.S. Department of Defense to ensure the data is unable to be recovered.

Secure Erase

According to National Institute of Standards and Technology (NIST) 800-88 Guidelines for Media Sanitization, Secure Erase is one of the ATA command. The data is totally and securely wiped from hard drives after implementation, and most of SATA hard drives on the market support Secure Erase.

Enhanced Secure Erase

Erase data by using SSD’s built-in ATA command. Additional actions will be executed according to different design of hard drives, e.g., destroying the encryption key on SSD to make the data unable to be decoded.

Erase HPA Area

Remove the HPA partition and free up the space.

Erase DCO Area

Remove the DCO partition.
