IMPORTANT NOTICES
Safety Notices
The warranty is void if an unauthorized person attempts and/or repairs the hard disk drive.

Rocstor® Rocsecure® DE51 [4]
Read all Manuals and instructions carefully before using the device.
Do not spill any liquid or insert any object into the device.
Use the device within the specifications indicated, including but not limited to: power requirements,
temperature, humidity, sunlight and magnetism from other devices such as computers and televisions.
The product information provided in this user’s manual is subject to change without prior notice and does
not represent a commitment on behalf of the Manufacturer or vendor. Rocstor nor vendor assumes no
liability or responsibility for any errors that may appear in this manual. Firmware, software, images, and
descriptions may vary slightly from actual products.
Please visit the Rocstor website, www.rocstor.com for further information concerning specifications and
use of the device.
General Notices
Consistently make multiple backup copies of your data for your protection. Hard disk drives are subject to
failure at any time.
Rocstorage, Inc. shall not be held liable for loss of data or the restoration or recovery of data on the
device. Please view complete Limited Warranty Information in this manual or on the Rocstor website
(www.rocstor.com) for further details.
Capacity Disclaimer
Actual accessible hard drive capacity will indicate up to 10% lower than stated under different Operating
Systems and formatting.
The storage volume is measured in total bytes before formatting. References to round numbers of gigabytes
or terabytes are an approximation only. For example, a disk drive labeled as having 500GB (gigabytes) has
space for approximately 500,000,000,000 bytes before formatting. After formatting, the drive capacity is
reduced by about 5% to 10% depending on the operating system and formatting used.
Care and Handling
The following instructions concern the proper care and handling of the Arcticroc 4-Bay RAID. Please take a
moment to review these instructions.
As with any storage solution, it is recommended that all data be backed up regularly.
Ensure that you follow the proper removal procedure to disconnect the RAID.
Do not move or disconnect this device from your computer while it is reading or writing
data. This may cause damage to the RAID.
Do not place this device near a heat source or expose it to direct flame.
Do not place the device near any equipment generating strong electromagnetic fields.
Exposure to strong electromagnetic fields may cause the device to malfunction or data to
be corrupted.
Do not drop or cause shock to your RAID.
Do not spill any liquid or insert any object into the device.
Do not attempt to disassemble and service the Rocpro drive during the warranty period.

Please read the Safety Notices and Limited Warranty information in this Manual and on the
Rocstor website (www.rocstor.com) for further details.
FCC-B RADIO FREQUENCY INTERFERENCE STATEMENT
This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions:
This device may not cause harmful interference.
This device must accept any interference received, including interference that may cause undesired operation.
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This equipment
generates radio frequency energy, and if not installed and used in accordance with the instruction manual,
may cause harmful interference to radio communications.
PRECAUTIONS FOR THE RAID SYSTEM
The main circuit board of the RAID System is susceptible to static electricity. Proper grounding is
required to prevent electrical damage to the RAID System unit or other connected devices, including the host
computer. Always place the RAID System unit on a smooth surface and avoid all dramatic movement,
vibration and percussion.
Any loss, corruption, or destruction of data is the sole responsibility of the owner/user(s). Under no
circumstances will the manufacturer be held liable for the recovery, restoration, loss … of any data.
Installation of MSU Software in the host computer is required for proper operation.
Do NOT allow water to enter the RAID System unit.
Installation of additional equipment in the host computer may be required. Visit our website to download
the latest product information updates.
Do NOT attempt to service this unit yourself. Disassembling the RAID System’s inner parts will expose you
to dangerous voltages or other hazards.
Do NOT block the ventilation. Proper airflow is required to ensure reliable operation and to prevent
overheating.
Do NOT place the RAID System close to magnetic devices (such as a mobile phone), high-voltage devices
(such as a hair dryer), or near a heat source (such as on the dashboard of a car or any place where it will be
exposed to direct sunlight).
Do unplug the RAID System unit from the electrical outlet when not in use to provide an ecological friendly
environment.
Use only the power supply cable provided with the RAID System unit.
Any loss, corruption, or destruction of data is the sole responsibility of the user of the RAID System.

Introduction
Rocsecure DE51
5 –Bay RAID Desktop Encryption Storage System
Rocsecure® Encryption products and solutions enable
you to efficiently control your data from
unauthorized users. With Rocstor, you can ensure
business continuity through variety of real-time
hardware Encryption Storage products
Rocsecure® DE51 Volume Raid solution is the most
reliable real-time hardware encrypted data solutions
available. Secure your valuable data with Advanced
Encryption Standard Algorithm AES-256 encryption
when regulatory mandates or the need to protect
intellectual property from security breaches dictate.
Rocsecure DE51 RAID Storage securely encrypts all data
in real-time as it is written to the drive. You have the
comfort of knowing that all data contained on these drives is protected against unauthorized access, including
hardware theft, failure of a drive, or drive retirement. The encrypted RAID storage data cannot be accessed
without the use of a unique Secure Key Token Authentication. The Rocsecure DE51 is authenticated by a digital
key token, which is inserted for authentication, and removed soon after the device is authenticated, and then
ready for secure data transfer.
Choose Rocstor drives and store your future.

MINIMUM SYSTEM REQUIREMENTS
To utilize the RAID, the minimum system configuration in the host computer requires the following:
3.5 or 2.5 inch SATA-compatible hard drive and/or 2.5-inch Solid State Drive(s) (SSD) are required for
the RAID System. Once the hard drive and/or SSD are formatted, the actual available storage
capacity can vary depending on the selected operating environment (normally 5-10 % less).
HARDWARE REQUIREMENTS AND PRECAUSIONS
1. Whenever turning off or unplugging the Rocsecure DE51 Series from your computer system becomes
necessary, always remember to safely remove it from your operating system first.
2. When the Rocsecure DE51 is connected to the computer system, it’s prohibited to remove, insert or
swap the hard drive while data transfer is being performed.
3. If you will be incorporating either software or hardware RAID functionality to operate with the ST4
Series, it is important to understand the RAID level and its component that will be incorporated and
the precautions to take as each RAID level and component may function differently and contains
various limitations.
4. If installing your own HDD, please make sure that the hard drives are free from bad blocks or defects
prior to installation in order to avoid system crashes or data loss.
5. It is highly recommended for users to back up important data contained within the drives of the
Rocsecure DE51 Series on a regular basis or whenever the user feels necessary to a remote or a
separate storage device. Rocstor will not be responsible for any loss of data caused during the use of
the DE51 Series or the recovery of the data lost.
