2. Introduction
2.1. Overview
Thank you for purchasing Portable USB2.0 DVD-ROM/CD-RW Combo drive. In this
manual, we will explain how to install your Combo drive correctly. Please read this
manual carefully before using the drive. The Combo drive provides 24X CD-RW writing,
24X CD-R writing, 24X CD-ROM reading and 8X DVD-ROM reading.
POWER-BURN
POWER-BURN is a new technology that automatically prevents buffer under-run errors
by predicting them before they happen. This Combo drive features POWER-BURN
technology to enable stable writing in the following situations where buffer under-run
errors may otherwise occur in a conventional drive.
y With high-speed writing,
y When some other operation is being performed on the computer during writing,
y When writing CD-R/CD-RW from a CD-ROM drive,
y When writing directly via network.
High Reliability
An improved anti-heat design and the OPC design boost recording reliability. Optimum
Power Control continually monitors signal levels during recording and adjusts laser
power to compensate for a dirty disc. This feature ensures a flat signal, significantly
enhancing reliability.
High Compatibility
The Combo drive supports all major CD formats, offering full backward-compatibility
through the huge installed base of CD/ROM drives and media. What’s more, reordered
CD/RW media can be played in a DVD player with multi-read feature, maintaining future
compatibility.

Introduction
2.4. Type of Writing
Disc-At-Once
When only a single recording session (lead in/data/lead out) is to be recorded onto a disk,
it is called “Disc-At-Once”.
When using Disc-At-Once, no additional data can be recorded onto the disc, even if
there is available capacity.
The advantage of this method recording is that it enables creation of discs that can be
played back on almost any CD player or CD-ROM drive, because there are no links
inserted between the data tracks.
Track-At-Once
When many sessions are to be recorded onto a disc, it is called “Track-At-Once”. If there
is space available on the disc, additional data can be recorded onto it.
The advantages of this method include being able to record additional sessions onto a
disc, and using a CD-ROM of backup data. (Refer to “Multisession”.)
Session-At-Once
A "Session-at-Once" recording almost corresponds to a "Disc-at-Once recording", i.e. all
data ("Lead-in", data area and "Lead-out" are written in one go.
The only difference is that the CD is not "finished", i.e. after a "Session-at-Once"
recording you still have the possibility to write a further "Session" on the CD at a later
date.
Multi-session
The recording of lead-in/data/lead-out is referred to as one session. The Disc-At-Once
method is also referred to as “Single Session”, because the disc is only recorded once. A
disc that has had multiple additional session recorded onto it using the Track-At-Once
method is called “Multisession”.
Packet Write
The Packet Write recording method was developed. It differs from Track-At-Once or
Disc-At-Once in that data is recorded in small fixed sectors of 64k bytes, known as
packets.
The advantages of this method are elimination in overhead per session and the
elimination of buffer under run errors. This method, however, cannot be utilized for audio
data. A number of formats, such as UDF and CD-R FS, can be used when recording
using the Packet Write method.

3. Hardware Installation
The installation of this Portable USB2.0 Combo drive is fast and easy. Please follow
these instructions described below:
3.1. System Requirements
A PC system with the following features is highly recommended for ensuring a stable
Combo drive performance.
y CPU: Pentium II 350 MHz or higher
y Operating System: Windows XP/2000/ME/98SE
y Memory: 64MB minimum, 128MB recommended
y CD-ROM Drive: Minimum 16X drive recommended
y USB2.0 Host controller card (Please be informed that you do not need to
install one if your motherboard is equipped with an USB2.0 controller on it.)
y USB2.0 certified cable (Included)
y Writing Software:
The drive requires CD writing software to write onto a CD-R/RW disc. When
you use the CD writing software, make sure that it supports this drive.
yHard Drive Space:
When writing to a CD-R/RW disc, you will need a working area (50 to 100 MB
free space) on the hard drive. When creating an image file for all data to write
to a CD-R/RW disc, in addition to the working area, you will need as much hard
drive space as that data (up to 800 MB in total). However, such hard drive
space for the image file is not needed when you are directly writing from a hard
drive, CD-ROM drive or so on (on-the-fly writing).
