Forensic Device User Advisory (3QJp
Models Only)
Before using this tool for accessing sensitive data, verify
the write-blocking function of the product. Attach a
known good formatted drive and verify that the drive
mounts properly on your computer. Copy les to the
drive. Due to the “spoof writing” style of write-blocking
employed by this product, the les will appear to copy
successfully. Next, unmount and remount the drive. The
les that you copied should not appear after the drive is
remounted. If they do appear, there is a problem with
your forensic device and you should contact our support
department for further instructions.

please ensure that all power switches have been turned
off and all power cords have been disconnected to
prevent personal injury and damage to the hardware.
• To avoid overheating, the unit should be operated in a
well-ventilated area.
• Remove the drives before transporting the unit to
prevent damage to the drive interfaces.
2 Installation Steps
2.1 Installing Hard Drives
a. Slide the drive carrier out of the RAX unit.
b. The carrier’s cover is held in place by a screw on the
rear of the unit. Remove the screw and then remove
the cover.
c. Slide the drive in from the front of the carrier.
d. Mate the connection on the drive with the connection
on the drive carrier circuit board.
e. Flip the drive/carrier assembly over and secure the
drive in place with the provided screws.
f. Attach the Temperature Control Cooling Sensor to the
top of the drive with a piece of tape.
g. Replace the carrier cover and secure the screw on the
rear of the carrier.
h. Slide the carrier into the RAX unit.
2.2 Selecting the Operation Mode for Each Bay
Each bay comes equipped with a switch on the front
bezel that switches between Read/Write Mode and Write
Protect Mode. Flip the switch for each bay to choose the
appropriate operation mode.
NOTE: This section refers only to 3QJp write protect
models.
R/W (Read/Write)
RAX 3QJp bays will operate like standard external hard
drives, performing standard read and write functions. The
drive bay must be set to R/W mode in order to format the
hard drive.
WP (Write Protect)
RAX 3QJp bays will protect data already on the hard drive.
The data on the drive can be read but cannot be altered.
NOTE: When changing the mode of operation the
new setting will not take effect until the power is
cycled or a drive is removed or added. The mode LED
will then change to indicate the new mode.
2.3 Host Connections
RAX units connect to your computer in one of four ways;
USB 3.0, USB 2.0, Firewire 800, or eSATA. Choose one of the
four cable types to use and plug it into the unit. Each bay
requires its own data connection.
2.4 Operating Your RAX Unit
a. Connect the data cables to the RAX unit and to your
computer.
b. Plug in the power cord to the RAX unit and to a
grounded electrical outlet.
c. If you have not already done so, slide the carriers into
the open receiving frames on the RAX unit.
d. Insert the Security Key into the Mini-USB Security Key
Port on the face of each receiving frame.
e. Insert a DataPort key into the key lock and turn it 90
degrees clockwise to power on the unit.
f. When both green LEDs are lit on both receiving frames,
showing that the drives are ready and encryption is
activated, remove the Security Key and store it in a safe
location.
When any hard drive is rst used with a RAX Secure unit,
it will show up as a blank, unallocated drive and you’ll need
to format the drive inside the unit before you can use it.
Note that formatting a drive will erase all data on
the drive, so be sure to back up your data before
beginning this operation.
NOTE: If any of the drives are inaccessible after
powering on the unit, try the following steps:
1. Turn off the power.
2. Remove the drive(s) in question.
3. Reinsert the drive(s).
4. Turn on the power.

4.1.2 Mounting and Unmounting Volumes
If the hard drive installed in the RAX unit is already
formatted, an icon representing the drive’s volume will
appear (mount) on the desktop. You can begin using
the volume right away. If the drive is unformatted, a
message will appear on the desktop saying that the disk
is unreadable. Use OS X’s Disk Utility to easily format the
drive (see section above).
Unmount the volume before
powering down the unit by
dragging the volume’s icon to the
Trash, or by selecting the volume
then pressing Command-E.
Disconnecting the unit without
rst unmounting the volume can
result in data loss.
4.1.3 Creating a Boot Drive
To activate this feature, you must rst install OS X on the
hard drive in your carrier. The easiest way to do this is
to clone an existing system drive using a utility such as
Carbon Copy Cloner or Super Duper. Next, go to System
Preferences →Startup Disk. A window will list the
available bootable volumes. Select the volume from
which you wish to boot. Another method is to hold down
the Option key during boot up. A screen should appear
that allows you to select the volume you wish to use. This
is useful if you are only sporadically booting from the RAX
unit hard drive.
4.2 Usage with Windows Operating Systems
4.2.1 Formatting a Drive
When you rst mount a drive to a Windows operating
system, a pop-up window will ask you if you would like
to format it. Click Format Disk and skip to Step E. If the
prompt does not pop up, use the Disk Management utility
by following these steps:
a. Right-click on the My Computer icon on the
desktop (Windows XP) or the Computer button in
the Start Menu (Windows Vista, 7, Server 2008 and
2012 product families), then select Manage. In the
left pane of the Computer Management window that
opens, left-click on Disk Management (labeled
‘A’ in the picture below). For Windows 8.1, press
WINKEY + X, then select Disk Management from
the menu that pops up.
b. The drive should appear in the list of Disks in the
lower pane. You may need to scroll down to see it.
If the drive is already formatted, you can identify it
easily by its volume name. If the Device Properties
Box (labeled ‘B’ in the picture below) says “Not
Initialized”, you’ll need to initialize the disk before
formatting it.

result in data loss.
Unmounting an eSATA Volume
If you purchased an eSATA host card that supports
hot-swapping, follow the instructions for unmounting a
USB or FireWire volume above. Many eSATA hosts do
not support this feature. However, freeware utilities are
available on the Internet that provide a similar function.
You may download one of these utilities or follow these
instructions: Ensure no le transfers are taking place by
making sure the Bay Access/Drive Activity LEDs are not
blinking, as disconnecting the unit while a le transfer
is in progress can result in data loss. Then disconnect
power to the RAX unit. You may need to restart your
computer in order to remount the RAX unit.
5 Rack Mounting Warnings
Elevated Operating Ambient Temperature: The operating
ambient temperature of the rack environment may be greater
than the room ambient temperature if the unit is installed in
a closed or multi-unit rack assembly. Install the equipment
in an environment compatible with the maximum ambient
temperature of 40° C.
Reduced Air Flow: Do not block or inhibit the air ow required
for safe operation of the unit.
Mechanical Loading: Ensure that the unit is secure and level
in the rack.
Circuit Overloading: Do not overload the circuits. Refer to the
name plate ratings on the equipment.
Reliable Grounding: Maintain reliable grounding of rack-
mounted equipment by using indirect connections to the
branch circuit (i.e. UPS battery backups, power strips).
Removing the Cover: Turn off and unplug the unit before
removing the cover.
select Initialize Disk. If you are prompted to select

dialog prompts, click Next on the Select Partition
Type (shows up in Windows XP only), Specify
Volume/Partition Size, and Assign Drive Letter or
Path dialog prompts, leaving the default settings.
e. You will now see a window that allows selection of a
le system. Choose NTFS and enter a name for the
new volume. Be sure to check the box labeled Quick
Format, which will ensure that the formatting
process takes less than a minute.
f. Click Next and then Finish to start the format
process. When the format is complete, the Drive
Properties Box will update to show the new volume
name. The new volume can now be found by double-
clicking on the My Computer icon on the desktop
(Windows XP), by clicking on the Computer button
in the Start Menu (Windows Vista, 7, Server 2008
product family), by clicking on Computer in the
navigation pane of a File Explorer window (Windows
Server 2012), or by opening a File Explorer window

devices attached to an eSATA host card. Sometimes
these devices will appear under the heading “Parallel
SCSI” instead. This is entirely normal and does not
indicate a problem with the device or its drivers.
Q: Why is my hard drive experiencing data corruption?
A: Many things can cause data corruption on hard drives,
whether they are inside your computer or inside an
external storage product. Malicious software, OS bugs,
failure to properly disconnect external devices, or for no
apparent reason at all. Data corruption or loss is therefore
not covered by warranty.
The rst thing to try is to restart both the computer
and the external device. If the data is still corrupted, try
running built-in OS utilities on the hard drive (such as
Mac OS X’s Disk Utility First Aid or Windows’ Check
Disk tool with the setting “Scan for and attempt recovery
of bad sectors” enabled).
If the OS utility doesn’t help, you may need data recovery
software. However, if there is a true hardware failure of
your hard drive that prevents it from communicating
with your computer, there is no software solution in
existence that can x this problem.
Q: Why won’t the computer let me eject or unmount my
drive?
A: There may be a software application running in the
background with an active link to the drive. Sometimes,
you may see a message such as “The disk is in use and
could not be ejected. Try quitting applications and try
again.”
This is not a defect or issue caused by the RAX unit.
Try invoking the Force Quit feature in OS X to see what
software may be running. For Window, the equivalent
command is CTRL+SHIFT+ESC.
Drives connected to the computer via eSATA cannot
be ejected in Windows the way FireWire drives can.
However, freeware utilities are available on the Internet
that provide a similar function.

6 Frequently Asked Questions
Q: Can I daisy-chain both bays together so I can connect to
the computer with a single FireWire cable?
A: Yes. But for best performance, don’t daisy chain other
Firewire devices to the same cable.
Q: When I change a drive to Write Protect Mode in my RAX
3QJp unit, I can still copy a le to the hard drive. Is the
le there?
A: No. The operating system will show the le on the drive,
but when you cycle power on the RAX 3QJp unit you
will see that the le is not actually there. Due to the
“spoof writing” style of write-blocking employed by this
product, any les you attempt to copy will appear to
copy successfully.
Q: Can I hot-swap drives with this product?
A: The RAX 3QJ and 3QJp units support hot-swapping over
USB and FireWire connections. If the eSATA/SATA host
supports this feature, the drives can be hot-swapped
via eSATA. All eSATA host cards currently sold by CRU
support hot swapping. Third-party host cards may or
may not support this feature.
Motherboard SATA connections often do not support
hot swapping, so a discreet host card is recommended.
Q: I’ve attached my unit and can see the volume, but it
shows up twice. Which one is real?
A: If you are seeing your volume mounted twice, chances
are the product is connected to the computer using
both the eSATA and FireWire connections. When this is
the case, the OS may attempt to mount the unit twice,
resulting in two volumes appearing. Simply turn off the
unit and unplug one of the connections to resolve the
problem.
Q: Can I hot-swap drives with this product?
