Diamond Cipher AES 256-bit Combo Hard Drive

Enclosure and Drive Cradle Overview

The drive enclosure is the enclosure where a SATA hard drive is mounted and
secured by 4 screws.

Drive cradle, also known as fixed tray, is the frame that mounts inside the drive
bay of a desktop, server or any computing equipment. The drive cradle provides
both power and data connection between the computer and the drive enclosure.

The Diamond cipher drive cradle fits into any standard 5 ¼” drive bay and can

connect to the computer via SATA or USB 2.0. This interface allows hot
swapping the hard drive without restarting or rebooting the system. The Diamond
drive cradle is compatible with all Diamond drive enclosures and Diamond cipher
drive enclosures. As a result you can insert SATA or IDE hard drive, encrypted or
unencrypted, into the same drive cradle of a computer.

Model: DCHD256ES & DCHD256EU

television reception, which can be determined by turning the equipment on and off, the user
is encouraged to try and correct the interference by one or more of the following
suggestions.
Reorient or relocate the receiving antenna

Diamond Cipher key

Check to make sure you have the correct version of the Diamond Cipher key.

The key should match the label at the back
of the drive enclosure.

Black label AES-256 stands for Diamond
Cipher 256-bit key

IMPORTANT
There is no back door for the Diamond Cipher encrypted hard drive if the

key is lost or stolen.

To ensure there is a spare key, your Diamond Cipher bundled kit comes with one
pair of Diamond Cipher keys. These 2 keys have identical encryption code. One
of these keys should be kept in a safe and secure location and can be sent back
to Addonics for duplicating additional keys. If you are down to the last key, be
sure to make a back up of all the data stored inside your encrypted hard drive
prior to sending the last key to Addonics. Addonics is not responsible for key lost
in the mail or retrieval of the data inside the encrypted hard drive.

 The CIPHER key MUST be inserted at the front of the drive enclosure in

order for the drive to be ACTIVATED.

 Once the drive is INITIALIZED using the Cipher Key that comes with the kit,

the drive can only be accessed by the original key.

 The 2 keys that come with each Diamond Cipher bundled kit has their own

unique encryption code. So the keys among different kits are not
interchangeable.

 If you have multiple sets of Diamond Cipher kits and would like all the keys

to have the same encryption code, you may make this request at the time of
your order or mail the keys together with master key back to Addonics to
recode them for you. Again be sure that you keep a spare key with you.
Make a back up of your data if you are mailing in your last key.

Keeping track of the hard drive
If you are using the Diamond Cipher drive enclosure to encrypt multiple hard

drives, it is important to label your hard drive if you are taking the drive out of the
enclosure. The hard drive with Diamond Cipher encryption will look like a brand
new drive when attach directly to the SATA controller of a computer. There will
be no partition or any hint to indicate that the drive contains encrypted data.
When the drive is partitioned, all the encrypted data will be lost.

The same holds true if a hard drive already has data on it is installed into the
Diamond Cipher drive enclosure. The computer detects the hard drive as a brand
new drive or a drive that is unallocated. Once you proceed to partition the drive,
the data that was on the hard drive will be erased and cannot be recovered.

A Diamond Cipher encrypted hard drive can be moved to another Diamond
Cipher drive enclosure. But the same key used in encrypting the hard drive must
be used in the new drive enclosure in order to access the drive.

If you are installing multiple Diamond Cipher drive kits in your
organization, it is important to keep track of the drive and the encryption
key. Once it gets mixed up, there is no possible way to recover the data on
the encrypted hard drive.

Hard Drive Installation Guide

Step 1

Use a Philips screwdriver to
turn the cover securing screw
into the “OPEN” position.

Step 2

Slide the aluminum cover
towards the back end of the
Diamond and remove it.

Step 3

Carefully place the SATA hard drive
with the label facing up into the
Diamond enclosure. Push the hard
drive towards the back end to secure
the drive connectors onto the

Diamond enclosure’s SATA

connector.
