ComboGB™
USER’S MANUAL
Revised October 2, 2006
Thank you for purchasing WiebeTech’s ComboGB, your best choice for a full-featured, ultra-
portable drive. The ComboGB offers maximum connectivity, performance and ruggedness, all in
a size that fits easily in your pocket. And because it comes with all the cables you'll need to plug
in to nearly any computer, ComboGB is one of the most versatile portable drives on the market.
Features
•Maximum connectivity – The ComboGB provides
native ports for three connection types: FireWire 400,
FireWire 800, and USB2. A total of five different cables
and adapters are included.
•Plug and Play – The ComboGB works with any
modern operating system, including Mac OS 9.1, 9.2,
OS X, Windows 2K, XP, and any distribution of Linux
that supports FireWire or USB. No drivers are
required.
•Fast Performance - FireWire 800 will outperform many
older desktop FireWire drives when configured with a
7200 RPM drive.
•Bus-Powered – Most FireWire ports and some USB ports provide enough juice to power the
ComboGB. The included USB power cord helps deliver additional power when bus power is
insufficient. An optional AC adapter is also available.
•Attractive and durable – The ComboGB also features an attractive case - a perfect balance of
aluminum and synthetic materials. The textured finish makes for a sturdy enclosure that's easy to
hold or pick up, while the brushed and embossed aluminum inset panel looks great. Its small size
allows it to fit right in your pocket so you can take it anywhere.

7.Secure the two halves together using 2 included screws (2 x 8mm).
8.Connect the data cable of your choice. The ComboGB can connect via FireWire 400, FireWire 800,
and USB 2.0. Plug one end of the appropriate cable into a port on the host computer, and the other end
to the ComboGB. If the host provides sufficient bus power, the green LED will illuminate and the drive
inside the ComboGB will spin up. Otherwise, you will also need to attach either the USB power cable or
the optional AC adapter.
Using the USB power cord
If bus power alone is not able to power the ComboGB, plug the included USB power cord into a USB port
of your computer. Plug the other end into the DC jack of your ComboGB. The power cord supplies DC
5V.
There is a pass-thru USB port on one connector. Some laptops will require the use of both connectors to
supply sufficient power.
Note:
If the ComboGB still cannot operate, your system may not supply enough power. You will need the
optional AC power adapter (DC 5V/2A). This is available from WiebeTech with the product code PWR-2.

Your ComboGB is now ready to use!
The red LED access indicator will light briefly after the drive spins up. This indicates that communication
with the drive has been established. Thereafter, it will light whenever the drive is accessed. If the access
LED does not blink shortly after drive spin up, it may indicate a problem with the drive or the ComboGB.
The most common problem is insufficient power. Contact technical support for further assistance if
necessary. If your hard drive is already formatted, you can begin using it right away. New hard drives will
need to be formatted before they can be used.
Usage with Macintosh Computers
Compatibility
The ComboGB is fully plug-and-play under Mac OS 9.1, 9.2 and OS X. No drivers are needed. FireWire 800 ports
are FireWire 400 host compatible (a FireWire 800-400 cable or adapter such as WiebeTech’s Cable-11 is necessary
for use with FireWire 400 ports). The USB2 port is USB 1.1 compatible.
Mounting and Ejecting Volumes
If the hard drive installed in the ComboGB 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.
You can use OS X’s Disk Utility to easily format the 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.
Booting from your ComboGB
Some Macs support booting from a FireWire device. To activate this feature, you must first install OS X on the
external volume. 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 ÆStartup 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 wish to
boot from your ComboGB only some of the time.
Usage with Windows Operating System
Compatibility
The ComboGB is fully plug-and-play with Windows 2000 and XP. No drivers are needed on these operating
systems. On systems running Windows 98SE or ME, the ComboGB is plug-and-play through FireWire. FireWire 800
ports are FireWire 400 host compatible (a FireWire 800-400 cable or adapter such as WiebeTech’s Cable-11 is
necessary for use with FireWire 400 ports). The USB2 port is USB 1.1 compatible.
Mounting and Ejecting Volumes
If the hard drive attached to the ComboGB is already formatted, you can begin using the volume right away. When
the ComboGB is properly connected and turned on, a window may open to allow you access to the volume. If no
window appears, you can find the volume by double-clicking the “My Computer” icon.
Eject the volume before powering down the unit by single-clicking the green arrow icon on
the task bar, then selecting “Safely remove….” Windows will indicate when it is safe to
disconnect the ComboGB. Shutting down the unit without first ejecting the volume can
result in data loss.
(Windows XP)
(Windows 98SE, ME, 2K)
Booting from your ComboGB
Some PC motherboards support booting from an external device. To activate this feature, you will need to adjust the
motherboard’s BIOS settings. Check with your motherboard’s manufacturer or owner’s manual for details.
