Notice About Using An External USB
CD-Rewriter
Maintain The Device Performance
If you want to maintain the CD-Rewriter’s better performance, we recommend you
connecting only one of the CD-Rewriter to your computer at a time. However, there is an
extreme reduction in performance when two or more of fast USB devices (such as
CD-ROM, CD-Writer, scanners, printers and hard drive) are used simultaneously.
)
NOTE: Please make sure your computer meets the system requirements
(or system configurations) shown on the box or on the next page of this
manual.
Prevent From the “Buffer Underrun” error
What is a buffer underrun? An uninterrupted data flow to the CD-Recorder drive is
needed when using mastering software like Easy CD Creator. A buffer underrun occurs
when the PC cannot consistently send the required data flow writing to the CD-Recorder.
If a buffer underrun occurs during writing, your CD-R disc is unusable anymore. To
understand how to prevent from the buffer underrun error, please refer to “What can I do
to prevent Buffer underrun?” on page E-11.

CD writing software installation
Before you start…
Please understand that CD recording is a non-interruptible process. Therefore, a stable
recording environment is a must. It is the best condition, if you have a HDD only for CD
recording purpose. That is, in this HDD, only Windows 98SE or higher and the necessary
software are installed, nothing else. Then the recording process will be smooth. However
if an extra HDD is not available, you might need to carry out the following steps to
optimize your Windows CD recording process.
1. Close all resident programs including 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.
2. Defragment your HDD before any CD recording. This is particularly important when
you write files to CD from HDD. Defragmentation of HDD reallocates all the files so
that these relevant files are placed in the nearby clusters. This saves time and risks
when Easy CD Creator is trying to search for the files you want to record on CD.
3. It is not advisable that you have too many devices internally connected to the
system. Heavy load carried by the system power supply may result in unstable
power delivery to each of the internal devices thus causes system unsteadiness.
Installing CD writing software
1. Load the software CD in CD-ROM or your CD-ReWriter.
2. Follow the instructions shown on screen and proceed to installation.
3. Some program may require your system to be rebooted after installation. Follow the
program's request to reboot your PC accordingly.

Frequently Asked Question (FAQ)
The following FAQ’s are the most common problems you may find during installation or
regular use. Please review these FAQ’s to have your problem solved. In case you do not
find any items that answer your problem, please contact your dealer or technical support.
Q: The CD-ReWriter doesn’t show up in My Computer or Explorer.
The following steps will assist you to get your drive to work as a CD-ROM:
 If you cannot find CD-ReWriter in Explorer, restart your computer, or shut it down
and then turn it on again.
 Make sure the computer is plugged in and that each device has power. To check if
the CD-ReWriter receives power properly, you can check the power indicator or test
it by pressing eject button to see if the tray opens and closes.
 Disconnect and then reconnect the CD-Rewriter’s power cable. This might fix a
faulty connection.
 Disconnect and then reconnect the USB cable.
Q: Not sure which drive letter was assigned to the CD-ReWriter.
The CD-ReWriter will have an icon, just like a CD-ROM drive. You can easily see which
icon is CD-ReWriter by double-clicking “My Computer”icon, then right-click CD drive’s
icon, and selecting Eject. The tray of selected drive will open.
Q: The CD-ReWriter has problem in reading CD disc.
There are several ways to solve this problem as follows:
 The CD disc in the tray may be loaded upside-down, or a little off-center. Try
re-loading the CD disc with its label side up.
 After loading a CD disc, it will take a moment to let the CD-ReWriter read the disc
information. When the indicator on the front panel stops flashing and stays green, it
is ready for access.
 If the disc you just loaded is a blank CD disc, try it later after copying some
information to the CD.
Q: Error message when double-clicking on the CD-ReWriter icon.
 If there is no CD in the CD-ReWriter, load a CD disc and try again.
 After loading a CD disc, you need to wait for a short moment to let the CD-ReWriter
read the disc information and ready for further access. The CD-ReWriter is ready
when the light stops flashing and stays green.
 The CD disc in the tray may be loaded upside-down, or a little off-center. Try
re-loading the CD disc with its label side up.
 If the disc you just loaded is a blank CD disc, try it later after copying some
information to the CD.
Q: What are possible causes of buffer underrun
Hard Disk
 Extremely fragmented hard drive.
 Not enough space in temporary directory.
 Hard disk compression may cause buffer underruns. We do not recommend writing
from a compressed hard disk or disk partition.
 "Dumb" thermal re-calibration (only on very old hard drives).

User’s Manual

-11
Other Hardware
 Spin-down of CD-ROM drives you're copying data or audio from.
 Slow source devices.
 Source devices that transfer data in bursts.
 Incorrect recorder controller settings.
 Inability of the devices to sync properly.
 Overall system configuration.
 Computer is unable to allow data transfer fast enough.
 Setting hard drive’s read ahead optimization to "none" may cure buffer underruns in
some cases. (Go to the Start menu | Settings | Control Panel | System |
Performance | Advanced Settings/File System | Hard Disk and set "Read-ahead
optimization" to "None.")
Networks
Recording across the network (a network may be too slow to maintain adequate
throughput speed).
Files to Be Recorded
 Recording many small files.
 Damaged source files (data loss).
 Trying to record files in use by the system or other applications.
Other
 Copying from a CD that is scratched, dirty, or damaged.
 Recorder malfunction
Q: What can I do to prevent Buffer underrun?
You can try the following procedures to prevent buffer underrun:
♦ Use a faster hard drive and defragment your hard drive at least once a week.
♦ Do not record across a network. Copy the desired files to your local hard drive.
♦ If your source hard disk is more than five years old, make sure it does smart
thermal re-calibration.
♦ It may be necessary to write audio at slower speeds than those you can achieve for
data, since writing CD-DA audio requires streaming more bits per second to the
recorder.
♦ Record in lower speed –it takes linger time to empty the buffer when recording at
lower speed.
♦ Keep the CDs, the recorder, and your source CD-ROM drive free of dust.
♦ Close all other application programs.
♦ Disable the screen saver and anti-virus programs.
♦ PC power management makes PC slower and thus it may result in buffer underrun.
Disable the power management or delay the power saving time.
♦ Keep your CD-R/CD-RW cool. Sometimes the drive fails when they overheat.
♦ Your system must fulfill the minimum configuration of yourCD-recording Mastering
software.
♦ Do not try to copy empty directories, zero byte files, or files that may be in use by
the system at the time of recording.
♦ If your data includes more than 10,000 very small files, create a disc image first, or
record at a slower speed.
♦ The temporary directory should always have space free at least twice the size of
the largest file you are recording.
♦ Try a different brand of recordable disc.

Q: Cannot directly copy from one CD to another.
 Some CD-ROM disc will not allow direct copying to the CD-ReWriter or are not
capable of digital audio extraction.
 You need to have a supported CD-ROM drive to use as your source.
 Some CD discs may have copy protections or other features that do not allow a
CD-to-CD copy.
Q: Poor audio quality.
 Make sure the audio cable is connected completely between the sound card and
CD-ReWriter or CD-ROM.
 Make sure that you do not have any sound-muting feature turned on by way of the
monitor or software.
 Try listening to the wave files (.WAV) on your hard drive to see if they sounded poor
before you copy them to CD.
Q: Unable to see a second session reading from a CD-ROM drive.
 Eject the CD and re-load it.
 Refresh the screen. Select the My Computer icon in Windows Explorer and press
F5.
 Make sure if your CD-ROM drive reads CD-RW discs. CD-RW discs can only be
used in CD-ReWriter or newer MultiRead CD-ROM.
 For Windows 3.x users: 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…” 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. That is a self-extracted
ZIP file. Please run it to retrieve MSCDEX.EXE file.
 See if the CD-ReWriter 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: Unable to see the CD label or all files on the CD within Windows Explorer.
Refresh the screen. Select My Computer icon in Windows Explorer and press F5.
Q: Applications cannot locate the CD in CD-ReWriter.
Some programs only locate the first logical drive letter assigned to a CD-ROM or a
CD-ReWriter drive. For example, if your CD-ROM drive is assigned to drive D and
CD-ReWriter is assigned to 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 CD-ReWriter
drives in case you need to run the program in CD-ReWriter.
 Windows: right-click My Computer icon. Click Properties item, 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 CD-ReWriter icon, then click Setting
tab. Under Reserved drive letters, select the drive letter before current one and
click OK.

Q: Can I use hard drive compression software?
It is not recommended to use hard drive compression software when CD-ReWriter is
installed. CD-R and CD-RW writing program may check free space to estimate needed
space. However, due to the hard drive compression software’s compression ratio may
vary from time to time. The actual free space available may not be enough for disc
copying.
Q: To maintain optimal writing performance
Regularly run disc de-fragmentation and scanning programs on your hard drive (please
refer to your Windows manual for detailed information). Doing this improves the access
time to the hard drive, and thus ensures writing in higher performance.
Finally, these are only GENERAL rules and not necessary to 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. Have a nice recording time.
