SAFETY PRECAUTIONS
Before using the Disk Jockey, please follow these important
safety precautions. Improper use of the Disk Jockey could
potentially cause serious harm or injury. We recommend
that you go through this document thoroughly before
attempting to use the Disk Jockey. Please be careful and use
common sense when working with your Disk Jockey.
General Disk Jockey Warnings
• If you see or smell smoke coming from the Disk
Jockey immediately remove the main power adapter
from the unit. Then remove the adapter from the wall
outlet as well. Please contact Diskology support at
[e-mail].
• Do not take apart the Disk Jockey. Failure to comply
with this request could cause shorts or possibly fire and
will void your warranty (NOTE - the PCB inside the
Disk Jockey is held inside on rails, therefore when you
shake the Disk Jockey there can be a rattling sound.
This is normal and does not effect performance).
• Please do not put foreign objects or water into the Disk
Jockey. If water or a foreign object gets into the chassis,
immediately remove the power to the unit and contact
Diskology support.
• Please use caution when working around water, drinks,
etc.
• Do not place the Disk Jockey on an unstable platform as
it could fall and cause damage to the unit, break the unit
or possibly case injury to the operator or to the people

6
around it. If you continue to use the Disk Jockey after
you suspect that it may be broken you could be at risk
for fire.
•Please only use the included power adapter with the
Disk Jockey. Please do not connect it to another power
adapter. Please make sure you insert the power cord into
the proper power outlet. If you happen to plug it into a
different power outlet beyond the spec of the unit it may
cause the unit to fail.
• Do not place heavy objects on the unit or on top of the
power adapter or power cord. Doing this could cause
damage to the unit or cause the unit to malfunction and
break.
Cautions (not as severe as Warnings but still not a good
idea to do these things)
• Do not use the Disk Jockey in extreme heat or humidity.
• Do not use the unit in direct sunlight or leave the unit
exposed to direct sunlight for extended periods of time.
• If you are not planning on using the unit for a long
period of time we recommend removing the power cord
from the unit and storing the unit in a safe place.
• If you are planning on moving the unit it is a good idea
to remove all of the cords and cables attached to the unit
before moving it. Moving the unit while cords are still
attached could cause shorts.
• Be careful when using the unit around large amounts
of static electricity. Static could cause the electronics
inside the Disk Jockey to fail. We recommend taking

7
all necessary static precautions including wearing anti-
static wristbands (not included) and grounding yourself
before working with the unit.

MAIN FEATURES
1. The Disk Jockey supports seven different copy and
diagnostic modes in one product.
2. The Disk Jockey copies a hard disk drive sector-
by-sector meaning that all OS files, partitions and
hidden files are copied. The Disk Jockey copies
data at speeds of over 2 GB/min. Copying an 80 GB
drive, for example, takes approximately 35 minutes.
3. The Disk Jockey can be used as a stand-alone unit
for high-speed disk copy, verify, test and erase
modes.
4. Supports RAID level 1 (mirroring) so that the
exact same data can be written to two drives
simultaneously. Disk spanning allows you to take
two disks of similar or different sizes and mount
them to the desktop of your computer as one logical
volume. Includes a disk compare mode, a disk
check mode using data verification and 2 erase
modes (one pass and three pass erase).
5. The Disk Jockey supports USB 2.0 as well as
FireWire (IEEE 1394).
NOTE - This unit was designed to use 2.5” and
3.5” UltraDMA IDE hard disk drives. It was not
designed to support CD-R, CD-RW or DVD drives.
6. The Disk Jockey supports Serial-ATA (SATA)
drives only with a SATA adapter (sold separately).

DISK JOCKEY OVERVIEW
The Disk Jockey is a very simple, but powerful unit.
Once you understand how the Disk Jockey works, you
can quickly and easily accomplish a variety of tasks with
the unit. In a nutshell, the Disk Jockey operates in two
distinct ways, attached to a computer and not attached to
a computer. The functions that can be accomplished while
attached to a computer, i.e. standard mode, mirroring and
spanning are completed in one fashion while the functions
accomplished while the Disk Jockey is not attached to a
computer are completed in a different fashion.
Before discussing how to work with the Disk Jockey we’ll
first cover the following areas:
Power LED
USB Port
IDE Connector

Power Button Mode Switch

AC
Firewire Port

1. The Disk Jockey layout, what the different parts of the
unit are called.
2. How to attach a hard disk drive to the Disk Jockey
3. General Rules for using the Disk Jockey that apply when
using any mode.
4. Working with the Disk Jockey modes.
Disk Jockey Layout
First we’ll take a look at the Disk Jockey itself to familiarize you
with the names of the different parts of the unit. The following
picture explains the different parts of the Disk Jockey:
NOTE – Pay particular attention to the Mode Select switch
on the Disk Jockey. A small screwdriver is shipped with
the unit to help you turn the mode switch. If you misplace
the screwdriver, any small, flathead screwdriver should
work. The Disk Jockey ships with the mode set to Mode 0,
or Standard Mode. In Mode 0 one or two hard disk drives
will mount to your desktop and can be treated as standard
external storage volumes. You may need to erase or
partition your hard disk drives prior to being able to access
them on your computer.
How to attach a hard disk drive to the Disk Jockey
One of the major benefits of the Disk Jockey is its “open
architecture” meaning that you can easily and quickly
switch hard disk drives and hard disk drive modes.
1. Before attaching a hard disk drive it is
recommended that you remove power from the Disk
