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.

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.
Hard 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).

4. Software Installation
4.1. Before You Start
Please understand that CD recording is a non-interruptible process. Therefore, a stable
recording environment is a must. If you have a HDD set up only for CD recording
purpose, the recording process shall be smooth.
However, if an extra HDD is not available, you might prefer carrying out the following
steps to optimize your Windows 98 / 98SE CD recording arrangement:
Close all resident programs that include Anti-Virus, Screen Saver, System
Agent, Power Management, etc. Turn off Auto Insert Notification. Further,
maximizing and minimizing windows are not recommended either. If not, any
operation of these applications will intrude the CD recording process and
damage your disk.
Defrag your HDD before any CD recording. This is particularly important
When you write files to CD from HDD. Defragment of HDD reallocates all the
files so that these relevant files are placed in the nearby clusters. This saves
time and risks when CD Burning Software is trying to search for the files you
want to record on CD.
4.2. Installing CD-R / RW Burning Software
The application CDs, free for users, can be found in the accessory bag. However, we
reserve the right to make changes to the application CD. These changes may be made
without advanced notice.
1. Nero Burning ROM
Nero Burning ROM is an exciting and powerful CD burning application. Please refer
to the README.txt file in the CD to peruse more detailed information about the
Nero Burning ROM.
2. NTI CD Maker
NTI CD Maker allows you click and drag the file; you want to save, into a file CD
similar to [File Manager]. Please put a formatted CD-RW into the Combo drive
before saving files.
3. Power DVD
Power DVD is one of the most popular VCD/DVD applications. Power DVD
supports a variety of VCD/DVD formats. Additional information about Power DVD
can be found in the README.txt file in the CD directory.
For information on installing procedures and how to use the authoring software, please
refer to the manual that came with it. If you want to use another type of authoring

created by Direct CD. If some other programs create the CD disc, please verify
you are using version 2.23 of the MSCDEX.EXE file. First, restart your PC and
when you see “Starting MS-DOS…” appear on your monitor, press F8. Each
line in your CONFIG.SYS and AUTOEXEC.BAT files will load one at a time.
Press “Y” until you see a line containing “MSCDEX.EXE”, then press “Y” and
you will see the version number displayed on monitor. The number shall be
2.23 or greater. In case you cannot find this file, you can download it from
Microsoft's FTP site: ftp://ftp.microsoft.com/Softlib/MSFILES/MSCD223.EXE
This file is a self-extracted ZIP file, please run it to retrieve MSCDEX.EXE file.
See if the CD-RW or other CD-ROM drives can read the CD disc properly. If so,
then the problem is probably with the CD-ROM drive. Contact the manufacturer
of the drive for updated drivers or patch files.
.
Q: Applications cannot locate the CD in this Portable USB2.0 Combo
drive.
Some programs only locate the first logical drive letter assigned to a CD-ROM
or the Combo drive. For example, if your CD-ROM drive is assigned drive D:
and Combo drive is assigned drive E:, the program locates drive D: only and
will not locate drive E:. Thus you need to reassign drive letters to both your
CD-ROM and Combo drives in case you need to run the program in Combo
drive.
Windows 98/98SE: right-click [My Computer]. Click [Properties] , open [Device
Manager] and double-click [CD-ROM drive], then click [Setting] tab. Under
Reserved drive letters, select the drive letter after the existing letter (for both
start and end drive letter) and click [OK]. Then double-click [USB2.0 Combo
drive] icon, then click [Setting] tab. Under Reserved drive letters, select the
drive letter before current one and click [OK].
The above are only GENERAL rules that do not necessarily apply to any combination of
CD-ROM drives, HDD and motherboards. A few trials on different configurations before
recording are recommended. Also, try out different CD-R media before you proceed to
make volumes duplication as you may figure out which brand of CD-R media originates
smoother recording and easier access. As long as you find the best CD recording way,
stick to it.
