1.3 Host Bus Adapter Installation
Install a host bus adapter (HBA) into an empty expansion slot inside your computer. If your computer
already has the connection type you need, you can skip this step. The following
general steps will work for most cards. Instructions for individual cards may vary,
so consult your host card’s user manual.
a) Power down the computer system.
b) Insert the card into an available slot. Do not force it, but it will take firm
pressure to insert it. Gently rocking the card into place may help.
c) Make sure the card is fully seated in the slot. Secure with a screw.
d) Turn the computer back on.
e) Install the appropriate software drivers for the card. The driver files are usually found on an
accompanying CD or on the manufacturer’s website.
All RTX TrayFree Bays accept up to 1.5TB
SATA drives, have power and access
LEDs, and connect to the controller via a
SATA connection.
WARNING: Do not block the ventilation
fan during operation. Overheating may
damage the device or hard drives.

2. Hard Drive Installation (Skip ahead if you purchased a pre-configured unit.)
Install a SATA (Serial-ATA) hard drive into each bay. With TrayFree™ technology, this process couldn’t
be easier! Simply pull the ejection handle to open the bay door, slide in your SATA drive, and shut the
door behind it. The drive is inserted with the label up and the SATA connection on the drive inserted first.
3. Understanding RAID
3.1 Consider your RAID type. (Skip ahead if you purchased a pre-configured unit.)
A RAID (Redundant Array of Independent Disks) is an array of multiple hard drives that are combined in a
way that provides faster performance and/or data safety. Your RTX unit is capable of creating and
managing several different varieties of RAID. You may choose your preferred RAID level based on
factors such as disk capacity, desired data safety, and desired performance.
3.1.1 Summary of RAID Levels
The RTX supports RAID Levels 0, 1, 3, 5 and 10. RAID level 5 is most commonly used by those seeking
an optimal balance of speed and data safety.
RAID Features and Performance
RAID

Drives
Data Reliability
Data Transfer Rate
0
Also known as striping. Data distributed
across multiple drives in the array. There is
no data protection.
1 4 No data Protection Very high
1
Also known as mirroring. All data replicated
on separated disks. RAID 1 is almost always
2 disks.
This is a high availability solution, but due to
the 100% duplication, it is also a costly
solution.
2 2 Very Reliable;
Higher than RAID
3, 5
Reads are higher
than a single disk;
Writes are similar
to a single disk
3
Also known as Bit-Interleaved Parity. Data
and parity information is subdivided and
distributed across all disks. Parity must be
equal to the smallest disk capacity in the
array. Parity information is normally stored
on a dedicated parity disk.
3 4 Lower than RAID 1,
10; Higher than a
single drive
Reads are similar
to RAID 0; Writes
are slower than a
single disk
5
Also known as Block-Interleaved Distributed
Parity. Data and parity information is
subdivided and distributed across all disks.
Can withstand the failure of one drive, and
75% of drive capacity is usable.
3 4 Lower than RAID 1,
10; Higher than a
single drive
Reads are similar
to RAID 0; Writes

Transfer rates are
more like RAID 1
than RAID 0
3.1.2 Hot Spares (Host Standby)
RAIDs 3 and 5 are the two RAIDs available with RTX400-QR that will support hot spares. Hot spares are
connected as part of your RAID and are switched into operation when a drive fails. In other words, if you
setup “3 + Host Standby” with your RAID 3 or 5, then the RTX will immediately rebuild the RAID if a drive
should happen to fail. After that a new drive will need to be inserted, preferably the same model of the
drive that is getting replaced. (see section 5.3.2.4 for more information)

4. RAID Configuration (Skip ahead if you purchased a pre-configured unit.)
To set up your RAID you’ll need to use WiebeTech Configurator 2.0. If you have not already installed
WiebeTech Configurator 2.0 then follow the steps below. If it is installed on your computer then skip
below to section 4.1.2.
4.1 WiebeTech Configurator 2.0
4.1.1 Installing WiebeTech Configurator 2.0
Configurator 2.0 can be found on our webpage (http://www.wiebetech.com/software/configurator.php) or
on the WiebeTech Product CD in the WiebeTech Extras folder.
•To install from the web, go to the webpage and select the Configurator that’s compatible with your Mac
or Windows Operating System.
•To install from the Product CD, open the folder called WiebeTech Extras, then open the folder called
WiebeTech Configurator. Both Mac and Windows versions will be in this folder, just select the
appropriate file and follow the installation instructions.
4.1.1.1 Windows Installation
If you’ve chosen the Windows version of WiebeTech Configurator 2.0, a Setup Wizard will appear on your
screen. Click “Next”. After you click “Next” it will take you to a licensed agreement for installing this
software. Read over the agreement and select “I accept the agreement”, then click “Next”. The Setup
Wizard will automatically create folders for WiebeTech Configurator. If you would like to install it in a
different folder on your system that’s acceptable, just click “Browse” and select a new location. Once
you’ve decided on where to store the software click “Next”. Shortcuts will automatically be installed in the
Start Menu under a subfolder called WiebeTech. Again, if you’d like to install this in a different area
select “Browse” and choose a different location. After you’ve decided on where to store the program’s
shortcuts click “Next”. Then you can opt to have a desktop icon installed. Make your selection and click
“Next”. After that the wizard will prompt you to install the software and will give a brief recap of the
different selections you have made. Click “Install” and let the wizard complete your installation. Finally,
you can choose to launch the Configurator now. Click “Finish” and open up WiebeTech Configurator 2.0.
4.1.1.2 Mac Installation
If you’ve chosen the version of WiebeTech Configurator 2.0, a License Agreement will appear on your
screen. You can select “Agree” and run WiebeTech Configurator straight from the source, or you can
select “Save” and save the software to your Mac. WiebeTech recommends saving it to your Mac as well
as placing an icon on your desktop for future use.
4.1.2 RAID Setup - Using WiebeTech Configurator 2.0
Open WiebeTech Configurator 2.0. A reminder will appear telling you to disconnect all other FireWire
devices. Be sure to do that and then select “Continue”. If configuring a RAID you’ll need to have your
drives loaded inside of the unit. When WiebeTech Configurator 2.0 appears you can power on your RTX.

4.1.2.1 Details Tab
The three tabs that appear house different information and changeable settings. The Details tab reports
basic information of the unit and is useful if you have a technical support issue. You can easily see the
name of the product, as well as firmware version. The Chip ID is a changeable setting, but we
recommend not changing that unless prompted by WiebeTech. Grayed out areas, like “Device Type”, are
features that are not supported by this particular chipset and they can be ignored.
4.1.2.2 Options Tab
There is only one selectable feature under the “Options” tab. Data read from or written to a drive is stored
in the drives cache memory. This cache is normally flushed on a regular basis but disabling it will stop
that action.

CRU-WiebeTech
R T X 4 0 0 - Q R U s e r ’ s M a n u a l - 8 -
4.1.2.3 RAID Tab
The RAID tab will be where you set up your RAID. First you need to startup the RTX400-QR without any
drives inside and the Configurator closed. After approximately 15 seconds you can open up Configurator.
Still without drives in the enclosure select the bubble next to your desired RAID type. Look over the
different features that are selectable in your RAID type and be sure that they are checked if you want
them. Finally, be sure to select the proper number of disks. If there is a grayed area when you are trying
to make your selection that means that the grayed feature is not compatible with the RAID type you’ve
selected.
Note: Windows XP can not recognize volumes larger than 2.2TB. If you are running Windows XP and
are using drives larger than 500GB you’ll need to deselect the “Enable Large Disks” feature. If you are
using Vista then be sure to initialize your volume as a GUID Partition Table (GPT) before formatting the
volume.
After you’ve made all of your choices select “Apply Settings”. You will see a progress bar like the one
above. When it says “Device Reinitializing” you can turn to the LCD display and the RTX400-QR will
prompt you “Re-init”. Press the left button to reinitialize your RTX. You can now insert you drives in a
timely manner. After the drives power up it will also verify the RAID set you selected and the number of
disks. Again, press the left button to verify the RAID set and disk number. The RTX400-QR will then
reset the drives and advance to the Active Menu. You can now close WiebeTech Configurator 2.0.
Note: Future reboots will prompt you to “Re-init” the RAID. If you are just rebooting your RTX400-QR
then let it complete the start up cycle and go to the “Active Menu” before you touch anything. If you Are
wanting to change your RAID type then let it complete the start up cycle and repeat 3.4.6. Data will be
lost if you “Re-init” the RAID.

5.2 Navigating the LCD Menu
5.2.1 Active Menu
The Active Menu is the RTX400-QR starting point. If the Active Menu is not displaying then either you
are in an erroneous state, setting up a RAID or checking enclosure/drive status. A healthy RAID set will
display the Active Menu screen.
5.2.2 RAID Mode
To view the RAID mode press the “Menu” (left) button below the Active Menu once. The next screen you
will see is the RAID Mode screen. From this screen press the “Go” (right) button below the LCD and that
will display the current RAID type and how many disks are in that RAID. Pressing the “Quit” (left) button
will take you back to the Active Menu.
5.2.3 Error Statistics
This section of the Menu will give you Persistent and Recoverable Error Statistics of each drive in your
RTX400-QR. To get there from the Active Menu press “Menu” (left) twice. Then press the “Go” (right)
button to go to persistent errors. If you want to view the number of persistent errors on your hard drives
press “Go” (right). If you want to view the number of recoverable errors on your hard drives press “Next”
(left). In either case it will take you through a port by port view of errors, where Port:0 is the first
bay/drive, and Port:1 is the second bay/drive etc. To go back to the Active Menu press “Next” (left) until
“Quit” (left) appears and then press “Quit” (left).
5.2.4 SMART Status
SMART (S.M.A.R.T.), or Self-Monitoring, Analysis, and Reporting Technology, is a monitoring system for
hard drives to detect and report various types of information. Some of those include spin-up time,
temperature and hours powered on. Another SMART attribute is the ability to inform a user if the hard
drive has SMART Status, or the ability to detect and report drive information. This section of the Menu
simply informs you if the drive has SMART Status. To view the SMART Status portion of the Menu press
the “Menu” (left) button three times, then press “Go” (right). This will take you through a port by port look
at the hard drives’ SMART Status, where Port0 is the first bay/drive, and Port1 is the second bay/drive
etc. To go back to the Active menu press “Next” (left) until “Quit” (left) appears and then press “Quit”
(left).
5.2.5 Enclosure Status
Fan Speed and Enclosure Temperature (C°) can be found in this portion of the Menu. From the Active
Menu press “Menu” (left) four times, then press “Go” (right). Your first screen will show the fan’s RPM
(Revolutions Per Minute), and the second screen will give the Enclosure Temperature in Celsius degrees.
Simply press “Next” (left) to view the temperature and “Quit” (left) to go back to the Active Menu.
5.2.6 Disk Temperature
Finally, the last section of the Menu reports hard drive temperature (C°). To view this press “Menu” (left)
five times, then press “Go” (right). This will take you through a disk by disk look at the hard drives’
temperature, where Disk 0 is the first bay/drive, and Port 1 is the second bay/drive etc. To go back to the
Active menu press “Next” (left) until “Quit” (left) appears and then press “Quit” (left).
5.3 Error States
5.3.1 Halted: Bad Disk Count
Halted: Bad Disk Count is an error most likely caused by bad sectors on a hard drive that has been
inserted in the RTX. It can also be caused by a hard drive that is not getting enough power to spin up.
This can either be caused by a faulty drive or a bad connection. In any case, contact WiebeTech
Technical Support to help you troubleshoot this error.

CRU-WiebeTech
R T X 4 0 0 - Q R U s e r ’ s M a n u a l - 11 -
5.3.2 Halted: RAID Invalid/Degraded
This error occurs when the RAID has encountered a problem, most likely caused by bad sectors or a
dead drive. This error will prompt a steady alarm and steady System access LED to the right of the LCD.
There are different steps to follow depending on what RAID type the drives are configured in.
5.3.2.1 RAID Invalid: Spanning
Since there is zero data protection in Spanning you will have to rebuild the RAID entirely. Insert a new
drive, preferably the same model of the drive that is getting replaced, and open WiebeTech Configurator
2.0 to set up a new RAID. (see section 4.1.2)
5.3.2.2 RAID Invalid: RAID 0
Since there is zero data protection in a RAID 0 you will have to rebuild the RAID entirely. Insert a new
drive, preferably the same model of the drive that is getting replaced, and open WiebeTech Configurator
2.0 to set up a new RAID. (see section 4.1.2)
5.3.2.3 Degraded: RAID 1
The loss of a drive in a RAID 1 will result in a degraded RAID state. The LCD display will show a
“Degraded” state and the RAID LED (yellow) will flash. The RAID can be rebuilt by removing the failed
drive and inserting a new drive, preferably the same model of the drive that is getting replaced. After a
new drive is inserted the LCD display will prompt you to “Add new disk.” Select “Yes” (left) and it will
begin the rebuild of the RAID. There will be a timer in the bottom right corner of the LCD that will give an
approximate time to completion. After the rebuild is finished the RTX400-QR will need to be rebooted. A
rebuild with 250GB drives will take approximately 45 minutes.
Note: A degraded RAID 1 will stay mounted and can continue to transfer data. However, WiebeTech
recommends disconnecting the unit during a rebuild if at all possible.
5.3.2.4 Degraded: RAID 3
The loss of a drive in a RAID 3 without Hot Spare will result in a degraded RAID state. The LCD display
will show a “Degraded” state and the RAID LED (yellow) will flash. The RAID can be rebuilt by removing
the failed drive and inserting a new drive, preferably the same model of the drive that is getting replaced.
After a new drive is inserted the LCD display will prompt you to “Add new disk.” Select “Yes” (left) and it
will begin the rebuild of the RAID. There will be a timer in the bottom right corner of the LCD that will give
an approximate time to completion. After the rebuild is finished the RTX400-QR will need to be rebooted.
A rebuild with 250GB drives will take approximately 75 minutes.
The loss of two drives will result in a RAID failure. New drives will need to be inserted, preferably the
same model of the drives that are getting replaced. Open WiebeTech Configurator 2.0 to set up a new
RAID. (see section 4.1.2)
Note: A degraded RAID 3 will stay mounted and can continue to transfer data. However, WiebeTech
recommends disconnecting the unit during a rebuild if at all possible.
5.3.2.4.1 RAID 3 with Hot Spare
If the RAID 3 is “3 + Host Standby” then no manual rebuild is necessary. The hot spare will automatically
be added to the RAID by rebuilding. At the end of the rebuild a new disk will need to be added, preferably
the same model of the drive that is getting replaced. The RTX will prompt you to “Add new disk” after
insertion. Select “Yes” (left). That disk will be the new hot spare for the RAID.
5.3.2.5 Degraded: RAID 5
The loss of a drive in a RAID 5 without Hot Spare will result in a degraded RAID state. The LCD display
will show a “Degraded” state and the RAID LED (yellow) will flash. The RAID can be rebuilt by removing
the failed drive and inserting a new drive, preferably the same model of drive that is getting replaced.
After a new drive is inserted the LCD display will prompt you to “Add new disk.” Select “Yes” (left) and it
will begin the rebuild of the RAID. There will be a timer in the bottom right corner of the LCD that will give

Note: A degraded RAID 5 will stay mounted and can continue to transfer data. However, WiebeTech
recommends disconnecting the unit during a rebuild if at all possible.
5.3.2.5.1 RAID 5 with Hot Spare
If the RAID 5 is “3 + Host Standby” then no manual rebuild is necessary. The hot spare will automatically
be added to the RAID by rebuilding. At the end of the rebuild a new disk will need to be added, preferably
the same model of the drive that is getting replaced. The RTX will prompt you to “Add new disk” after
insertion. Select “Yes” (left). That disk will be the new hot spare for the RAID.
5.3.2.6 Degraded: RAID 10
The loss of a drive in a RAID 10 will result in a degraded RAID state. The LCD display will show a
“Degraded” state and the RAID LED (yellow) will flash. The RAID can be rebuilt by removing the failed
drive and inserting a new drive, preferably the same model of drive that is getting replaced. After a new
drive is inserted the LCD display will prompt you to “Add new disk.” Select “Yes” (left) and it will begin the
rebuild of the RAID. There will be a timer in the bottom right corner of the LCD that will give an
approximate time to completion. After the rebuild is finished the RTX400-QR will need to be rebooted. A

6. Usage with Mac and Windows Operating Systems
6.1 Usage with Macintosh Computers
6.1.1 Compatibility
The RTX400-QR is compatible with Mac OS X. No drivers are needed.
6.1.2 Using Volumes
When you connect the unit to the Mac for the first time and turn on the power, you’ll
probably see a message saying that the disk is unreadable. This is because you
must format the volume before using it. The easiest way to do this is to use Mac OS
X’s Disk Utility. If you plan to use the unit on both Macs and PCs, select “MS DOS
File System” as the format type. If you only plan to use the unit on Macs, then select
“Mac OS Extended”. After the volume is formatted, an icon representing the drive
volume will appear (“mount”) on the desktop. You can now use the volume just like
an internal hard drive.
Eject the volume before powering down the unit by dragging the volume’s icon to the trash bin, or by
selecting the volume then pressing Command-E. Shutting down the unit without first ejecting the volume
can result in data loss.

6.2 Usage with Windows Computers
6.2.1 Compatibility
The RTX400-QR is compatible with Windows XP (2.2TB limit) and Vista. No drivers are needed.
6.2.2 Using Volumes
Before you can use your RTX400-QR, you must first format the drives into a volume. Use Disk
Management, which you can find by right-clicking on My Computer then selecting Manage. Select NTFS
for the format type. If you wish to format FAT-32 for cross-platform compatibility, you will need to use a
third-party utility to do so. Windows XP will not create FAT-32 volumes larger than 32GB.
After the volume is formatted, an icon representing the drive volume will appear in My Computer. You
can now use the volume just like an internal hard drive.
If the RTX is connected to your computer via FireWire or USB, always eject the device by clicking the
taskbar “eject” icon before turning off power or unplugging the data cable. Failing to do so could result in
data corruption on the drive. When connecting via eSATA, you will not be able to eject in this way.
However, it is possible to disable the device using Device Manager. Whether or not you choose to
disable the device in this way, always make sure the drives are not being accessed before shutting off the
RTX400-QR to avoid data loss.
7. Frequently Asked Questions (FAQ)
Q: I've attached my RTX400-QR and can see the volume, but it shows up twice. Which one is the real
volume?
A: If you are seeing your RTX400-QR volume mounted twice, chances are the unit is connected to the
computer using both the eSATA and FireWire connections. When this is the case, the OS may attempt to
mount the RTX twice resulting in two volumes appearing. Simply turn off the RTX and unplug one of the
connections to resolve the 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."
It could be a background application like Sherlock or the Finder. This is not a defect or issue caused by
the WiebeTech device. Try invoking the Force Quit feature in OS X to see what software may be running.
For Windows XP, 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.
Q: What is an acceptable temperature for my hard drives and RTX400-QR?
A: You hard drives can run at between 30-40°Celsius without any risk of overheating. The RTX400-QR
should trigger the fans to operate when the enclosure reaches 36° Celsius, so ideal temperatures should
also range from 30-40°Celsius.
Q: Why does my eSATA device appear as a Parallel SCSI device in System Profiler?
A: The "Serial ATA" tab in System Profile shows devices attached to the internal SATA bus, but not
always 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: What is the difference between recoverable and persistent errors?
A: Recoverable Errors (aka Transient Error or Disk Error) represent minute errors that the RAID system
encounters during data transfers. These errors are common for RAID setups and are not necessarily
indicative of a drive failure. It is normal for any given disk in a RAID array to occasionally encounter and
report these errors, but a string of these errors may indicate the upcoming failure of that particular disk.
Persistent Errors (aka Hard Error or Disk Failure) represent the major errors that can affect a drive and
cause it to be removed from the RAID array. This can be caused by electrical removal (e.g. drive is
physically disconnected from the controller, drive suffers electrical failure, drive looses power, etc.) or by a
failure to respond (e.g. the given disk no longer responds to commands given by the controller). In either
case, the result is a degraded RAID set and a failed disk.
Q: What should I do on a reboot when the RTX400-QR prompts me to “Re-init” the RAID?
A: If you bought an RTX400-QR without drives and you want a RAID 5 with 4 disks (default RAID type)
then simply insert your drives and select the “Re-init” (left) button on the front display. RTX400-QR will
verify the RAID 5 with 4 disks and you can select the “-Init” (left) button on the front display to set up that
RAID.
If you desire a different RAID type or disk number refer to section “4.1.2.3 RAID Tab” in the User Manual
for further instructions.
If you are simply rebooting the unit and want to return to the “Active Menu” then let the RTX400-QR
complete the start up cycle and it will arrive at the “Active Menu” momentarily. Do not press any buttons
on the front display.
