• Archive images and video to DVD or CD.

• Master new software programs on DVD or CD.

About Software

In order to record on DVD±R DL, DVD±R/RW, and CD-R/RW discs
you will need to have mastering, packet writing, or duplication software
installed on your computer system. If you purchased a retail kit from
Plextor, you’ll get software packages that include such software.

Ahead’s Nero software is one software suite that lets you burn DVDs
and CDs. The software lets you burn and share anything on CD or DVD,
including music, photos, and videos; and you can easily back up your
critical data to a CD or DVD. One component of Nero is InCD 4, which
makes the Plextor PX-740UF drive as easy to use as a hard disk drive.
(For more information about Nero, install this application and examine
the help files.)

For details on other software that is available for writing to DVDs or
CDs, please visit the web sites of the companies whose software you are
interested in, refer to their user’s manuals, or look at the help option
within the software. A list of various software that you can use with
your Plextor drive can be found in the Support/Compatibility section of
www.plextor.com

Precautions

Like the rest of your computer system, your PX-740UF requires
reasonable care in its installation and use.

• Keep the area around your drive clean from dust, smoke, and other

contaminants.

• Do not allow moisture or liquids, including water or cleaning fluids,

to touch the drive. Thinner, benzene, or alcohol-based solvents can
mar your drive’s surface.

• Do not drop or jolt the drive.

• Do not move, carry or transport a disc in the drive because this can

cause damage.

• Do not attempt to open the drive and service it yourself. Removing

the cover may expose you to harmful electrical voltages or the laser
beam. For your safety, entrust service to experienced service
personnel only.

• Keep your DVDs and CDs free of dirt or other contaminants, by

storing them in jewel cases. Use only industry-standard discs. Do not
insert dirty, warped, poorly balanced, or cracked discs into the drive.

• Do not clean discs using a circular motion. Instead, using a soft, dry

cloth, wipe gently in a radial motion; start at the center of the disc
and proceed to the outer edge.

• Do not attempt to clean your drive using solvent-based cleaners or an

air compressor.

• Do not attempt to clean your drive using a CD cleaning disc. These

discs can damage your drive permanently.

Section 2. Installing the PX-740UF External USB/FireWire Drive

What Else Is In the PX-740UF Box

What you find in your Plextor box depends on what the company that
sold you the box put in—or took out—while the Plextor drive was in
their possession. Plextor currently sells the PX-740UF drive in this
configuration:

• PX-740UF DVD±R DL, DVD±R/RW and CD-R/RW drive

• USB 2.0 cable

• AC adapter and power cord

• Emergency eject tool

• Plextor software disc with a PDF file of the PX-740UF Installation

and Users Manual. Also contains Ahead Software’s Nero OEM
Suite.

• Drive Installation Guide

Save Your Box!

Be sure to save the box after you have installed your drive. The box
and its packaging material were designed and drop tested to ensure
your drive can endure rough treatment and still arrive in working
order. If you have to ship your drive back to Plextor, you’ll want to
send it in the original box. (For more details about returning your
drive to Plextor, see page 53.)

If the security sticker on top of your box is cut, there may be a good
reason: for example, a dealer may have added other components or
software. Carefully check the contents to ensure nothing has been
removed. If something is missing, contact the party from whom you
purchased the box for an explanation.

NOTE: This applies to the Plextor retail box. Your drive may have been
shipped in a different box with other contents, depending on whom you
purchased the drive from and what they included inside the box.

If your drive came pre-installed, some or all of the items above may
have been installed and may not be separately available. See the Plextor
web site for locations to purchase additional or replacement accessories.

PX-740UF Installation and Users Manual 13

Section 2. Installing the PX-740UF External USB/FireWire Drive

Mount the PX-740UF Drive

This section explains how to physically connect the PX-740UF external
drive to your computer. In general, this is what you’ll do:

1. Determine what operating system your computer is running. Your
computer must be running Windows XP, XP 64-bit, 2000 or Me; or
the Macintosh Mac OS X operating system.

2. Determine which interface you want to use: FireWire (IEEE 1394)
or USB.

3. Set the PX-740UF interface switch for IEEE 1394 or USB.

4. Connect the AC adapter to an electrical outlet and to the PX-740UF.

5. Turn the drive’s power switch ON (the “1” position).

6. Connect the USB cable or a FireWire cable (corresponding to the
setting of the interface switch) from your PX-740UF drive to the
computer.

That’s all there is to it! We’ll go over the procedure in more detail in the
next few pages.

If you have a PC, start here. If you have a Macintosh, go to “If You
Have a Macintosh” on page 20.

14 PX-740UF Installation and Users Manual

Section 2. Installing the PX-740UF External USB/FireWire Drive

Determine Your Computer’s Operating System

To determine which operating system your personal computer uses:

1. In Windows, select the Start menu, then select Settings, then Control

Panel, and choose the System icon. You see the System Properties
window.

2. In the System Properties window, make sure the General tab is

selected. The System line shows details about your operating system.
(For example, “Windows 2000.”)

NOTE: Your computer must be running Windows 2000, Windows Me or
Windows XP (or Mac OS X). If you are not running one of these
operating systems you cannot use the PX-740UF. You cannot use the
PX-740UF with Windows 98 or Mac OS 9.

Determine What Interface to Use

You can use either USB 2.0 or FireWire. The built-in USB ports on
older computers (and even on inexpensive new ones) provide only
USB 1.1—that is, Full-Speed (12 Mbps) USB.

For optimum performance:

• If your PC does not have built-in USB 2.0, use the FireWire port, if

available.

• If you have neither USB 2.0 or FireWire, you can purchase and

install a third-party PCI USB 2.0 or FireWire plug-in host adapter
card.

• If you don’t want to purchase a separate card, you can use your PC’s

built-in USB 1.1 port. However this limits the CD-RW drive
performance of the Plextor PX-740UF to 4X write, 4X rewrite, and
6X read. DVD performance with USB 1.1 is 0.7X.

the PX-740UF to be recognized.

PX-740UF Installation and Users Manual 17

Section 2. Installing the PX-740UF External USB/FireWire Drive

CAUTION FOR USB: If possible, always connect the PX-740UF directly
to the computer’s USB port. Connecting the PX-740UF to a USB hub is
not recommended. Connecting through a USB hub may reduce the
drive’s performance.

CAUTION FOR IEEE 1394: To guarantee rated performance with IEEE
1394/FireWire, the PX-740UF should be the only device on the cable.
Daisy-chaining the PX-740UF with other IEEE 1394/FireWire devices
may reduce performance.

Identifying Cables and Ports

This illustration will help you identify the cables and computer ports and
make the necessary connections.

Figure 4: Identifying cables and ports on your computer

18 PX-740UF Installation and Users Manual

Section 2. Installing the PX-740UF External USB/FireWire Drive

Switching Between USB and IEEE 1394 Interfaces

You can connect any or all of the interface cables (USB, IEEE 1394
4-pin, and IEEE 1394 6-pin) and switch between them. You can even
have different cables attached at the same time, allowing more than one
computer to share the PX-740UF.

To switch between interfaces attached to the PX-740UF:

1. Ensure an interface cable for the desired USB or IEEE 1394

interface is attached to the PX-740UF and to the computer.

2. At the rear of the PX-740UF, set the interface switch to the desired

interface.

3. Cycle the PX-740UF power. (That is, turn the PX-740UF’s power

switch off, then on again.)

If You’re Using FireWire

If you are using FireWire (IEEE 1394), remember these hints for better
operation:

• Do not daisy-chain the PX-740UF; that is, do not connect it to the

same cable along with other FireWire devices.

• The PX-740UF is not bus powered—that is, it doesn’t get its power

from the IEEE 1394 cable—so you have to use the bundled AC
adapter.

3. On the PX-740UF, set the rear-panel interface switch to USB or
IEEE 1394, corresponding to the interface you will be using.

4. Connect the AC adapter to your PX-740UF.

5. Turn the drive’s power switch ON (the “1” is depressed). The power
indicator is illuminated when power is applied.

6. Connect the USB cable or an IEEE 1394 cable from your PX-740UF
drive to the Macintosh computer.

The Macintosh automatically recognizes the PX-740UF (if the base
extensions are loaded), and you should be ready to use the drive as a
CD-ROM. To use the recording capabilities of the drive, a recording
application must be installed.

NOTE: For optimum performance, if your Macintosh computer does not
have built-in USB 2.0, use the FireWire port. Or you can install a third­party PCI USB 2.0 plug-in host adapter card.

3. Using Your PX-740UF

This section explains how to use your PX-740UF drive and how to load,
handle and care for your DVDs and CDs.

What Media to Use

Use the right media! Your PX-740UF drive's capabilities change
depending on which type of compact disc you use.

DVD Media

DVD recordable media is available in two different, non-compatible
formats:

• DVD+R, DVD+R DL (double layer) and DVD+RW

• DVD-R, DVD-R DL (dual layer) and DVD-RW

Your PX-740UF can read and write either media format, in single layer
or double layer media. It supports all these types of DVD media:

• Digital Video Discs: You can immediately play pre-recorded DVD

discs, including movies and other DVDs.

• DVD+R DL, DVD-R DL, DVD+R, DVD-R: Recordable DVD.

You can record on these discs, but only once. You can also read
them.

• DVD+RW, DVD-RW: ReWritable DVD. You can record and re-

record (up to 1,000 times) on these discs. You can also read them.

Figure 5: The logo identifies the type of DVD media

With double layer media, you don’t need to turn the disc over to record
on side 2.

PX-740UF Installation and Users Manual

Section 3. Using Your PX-740UF

CD-ROM Media

In addition, you can use these types of CD media:

• CD-ROM: You can immediately play or read prerecorded compact
discs, such as audio CDs and data discs.

• CD-R: Recordable CD. You can record on these discs, but only
once. You can also read them.

• CD-RW: Normal Speed, High Speed, Ultra Speed, and Ultra Speed
Plus ReWritable CD. These discs support recording and re-recording
(up to 1,000 times). You can also read them.

To achieve a certain writing speed, you must use the appropriate media.
To achieve 48X CD-R writing speed you must use certified 48X media;
and to achieve 32X CD-RW writing speed you must use Ultra Speed
Plus CD-RW media.

Remember:

• Using Normal Speed CD-RW discs (that is, NS-RW media) you can
rewrite at 4X.

• Using High Speed CD-RW discs (HS-RW media), you can rewrite at
4X or 10X.

• Using Ultra Speed CD-RW discs (US-RW media) in this drive, you
can rewrite at up to 24X.

• With Ultra Speed Plus CD-RW discs (US-RW+ media) you can
rewrite at up to 32X.

You can write to Ultra Speed CD-RW discs only on drives that support
this media. Drives that are capable of writing to Ultra Speed ReWritable
media, such as the Plextor PX-740UF, are identified by a “Compact
Disc ReWritable Ultra Speed” logo.

Figure 6: The logo also identifies the type of CD-RW media

See “Recommended Media” on page 40 for a list of Plextor-approved
media at the time this manual was printed, and see the Plextor web site
at www.plextor.com

for an updated list.

Section 3. Using Your PX-740UF

Tray Loading and Operation

To load and unload the tray:

1. While the drive is powered up, push the eject button on the front

panel. The tray drawer slides out in 3–4 seconds.

Figure 7: Loading the tray

2. Lay a CD or DVD disc in the depression in the tray, label side up.

3. Press the eject button again and the tray will slide shut within

seconds.

NOTE: Always use the eject button to close the tray in a smooth and
secure manner. Closing the tray by pressing the front of the drawer using
your hand is not recommended and risks damage or premature wearing
of the mechanism.

Handling DVD and CD Media

Take care when handling blank CD and DVD media. Dust, scratches,
and fingerprints on either side of the disc can cause write errors during
recording. When picking up or holding blank media you can either place
your fingers along the outer edge of the disc, or place one finger through
the center hole and one finger on the outer edge. Once you have finished
creating a disc, label it by writing on the top using permanent ink.

CAUTION: We recommend using a “non-toxic” marker, such as a
Sharpie pen, that conforms to the ASTM D-4236 standard. Some
permanent markers will damage the media. Also, do not press too hard
when writing on the disc.

PX-740UF Installation and Users Manual 23

Section 3. Using Your PX-740UF

NOTE: We do not recommend placing self-sticking CD-R labels on the
disc. The weight of the label may unbalance the disc and cause write
errors during recording or read errors during reading. Also, attempting to
remove the label may permanently damage the disc.

Cleaning Discs

For proper read and write performance, your discs must be clean. Trying
to record on a dirty disc may result in a failed session and ruin the disc.

To clean the disc, wipe the disc using a clean, soft cotton cloth to
remove surface dirt such as fingerprints. Use a straight-line motion,
wiping from the center out. Do not wipe the disc in a circular motion.

Figure 8: Wipe the disc from the center outward

HINT: Keep your frequently used discs in jewel cases at all times to
prevent them from becoming dirty or damaged.

Section 3. Using Your PX-740UF

Mounting Position

You can operate your PX-740UF drive in either a horizontal or a vertical
position.

Figure 9: Operate the PX-740UF either horizontally or vertically

CAUTION: In the vertical position, the PX-740UF is more susceptible to
shock. If using the drive in a vertical position, be careful not to disturb it.

Playing DVDs

To play a digital video disc, insert the DVD as you would any other
disc. The drive plays both single layer and double layer discs.

The first time: A code on each DVD allows it to be played only on
players designed for a certain regional area, such as North America,
Europe, etc. When the drive ships from the factory there is no region
code set. The first time a DVD that has a region setting is inserted into
the drive, the drive is automatically set to that region code.

PX-740UF Installation and Users Manual 25

Section 3. Using Your PX-740UF

If you later insert a DVD with a different region code, you are prompted
to either accept changing the new region code or not. If you don’t accept
the change, then that DVD will not play. If you do accept the change,
then the region code setting is changed. But remember: you can change
the drive’s region code only 5 times. After that, you can’t change it any
more.

Writing to DVD Media

You need special software that supports writing to DVD+R,
DVD+R DL, and DVD+RW discs; or to DVD-R DL, DVD-R and
DVD-RW discs. Ahead Software’s Nero 6 OEM Suite (on the CD that
accompanies your PX-740UF) contains this software.

Specifying +R/RW or -R/RW

You don’t need to specify whether to write to +R/RW or -R/RW. The
selection is automatically made for you, based on the media you insert in
the drive.

Writing to CD-R and CD-RW Media

In conjunction with your drive, mastering and packet writing software
such as Ahead Software’s Nero or Roxio Easy Media Creator 7 allows
you to write audio, video, data, or other information to writable (CD-R)
or rewritable (CD-RW) media. The PX-740UF writes to all types of CD­RW media.

4. Maintenance and Troubleshooting

This section explains maintenance and troubleshooting procedures for
your PX-740UF drive.

With proper maintenance, you can prevent problems. If trouble arises,
you can often solve many simple problems on your own, rather than
wait for assistance from a Plextor representative.

Cleaning the PX-740UF Drive

Plextor drives are sealed against external contamination, so in a normal
computer environment and with normal use, your drive should not
require internal cleaning. However, if your drive has been in use for
some time and has just recently started to exhibit read/write problems, it
is possible that dust has accumulated on the laser lens. In this case:

• If your drive is still in warranty and you are experiencing problems,

send the drive to Plextor. (See “Returns” on page 53.)

• If your drive is out of warranty, before returning the drive for repair

you may want to try a short blast of canned air aimed at the center of
the drive. Use only electronics-grade canned air: sterile, filtered, and
moisture-free. If you notice no improvements after this step, you will
need to return the drive for repair.

CAUTION: Do not attempt to clean your drive using any solvent-based
cleaners. Also, do not use an air compressor, because the high-pressure
blast can damage the drive.

ANOTHER CAUTION: Do not use a CD cleaning disc. Cleaning discs
that use a felt pad can scratch the laser lens surface and render the drive
inoperable. Cleaning discs with brushes may also scratch the lens.
Moreover, these cleaning discs are often out of balance, making their
operation very noisy.

Section 4. Maintenance and Troubleshooting

4. If you have a PX-740UF drive that is not recognized in Windows:

a) If your USB or IEEE 1394 controller has a yellow diamond with
an exclamation point (!), contact your PC or motherboard
manufacturer for help, and to troubleshoot your controller for driver
compatibility or conflicts. It may just be a matter of obtaining the
latest driver, or a motherboard BIOS update, from the manufacturer.

b) If the USB or IEEE 1394 controller is listed and does not have a
yellow diamond with an exclamation point, but the Plextor drive is
listed as a “USB” or “IEEE 1394 Storage device,” select the
“Storage device” and then select the “Remove” button. Reboot your
system. The system will do another hardware scan and should install
the driver properly.

5. If you still have problems, or if the USB or IEEE 1394 controller is

listed and does not have a yellow diamond with an exclamation
point, but you do not see the Plextor drive listed as one of the
devices, contact Plextor Technical Support. (See “Appendix B:

5. Frequently Asked Questions

Q: Which is better, DVD+R and DVD+RW? Or DVD-R and DVD-RW?

A: Neither is “better” or “worse.” They’re just different standards, like
English versus metric measurement.

Different manufacturers support different standards. The DVD+R and
DVD+RW formats are supported by Plextor, Philips, Sony, Hewlett­Packard, Dell, Ricoh, Yamaha and other manufacturers. DVD-R, DVD-RW
and DVD-RAM are also supported by Plextor, as well as Panasonic,
Toshiba, Apple Computer, Hitachi, NEC, Pioneer, Samsung and Sharp.

No matter which format a DVD disc is recorded in, it can be read by most
commercial DVD-ROM players.

Q: What's the difference between "double layer" and "dual layer"?

A: Nothing, really. It's simply a difference of opinion within the industry
about how to label media and drive capabilities. DVD+R DL (as named by
the DVD+RW Alliance) stands for DVD+R Double Layer. DVD-R DL
(from the DVD Forum) stands for DVD-R Dual Layer. Whether your DL
media is labeled "double layer" or "dual layer," the PX-740UF can handle it.

Q: What is “recommended media”?

A: Recommended media are recordable or rewritable CD and DVD media
that have been tested by Plextor and found to operate well consistently, from
one manufacturing lot to another. For each drive, Plextor engineers test
media from many different manufacturers and manufacturing facilities,
creating a recommended media list and determining the optimum write
strategy for that particular media type. The results are listed as
“recommended media,” and are also assembled into a media catalog and
stored in firmware in Plextor drives. (See page 40 for a list of recommended
media for the PX-740UF at the time this manual was printed, and see the
Plextor web site at www.plextor.com

From time to time, the media catalog is updated with new manufacturers and
part numbers as Plextor tests additional media. When this happens, Plextor
makes new drive firmware available. You can download this new firmware
and update your drive.

for an updated list.)

PX-740UF Installation and Users Manual

Section 5. Frequently Asked Questions

Q: In the list of Recommended Media, what’s the difference between
“rated,” “compatible,” and “recommended” speeds?

A: “Rated” is the manufacturer’s rated write speed for the media; it’s what
you see on the box. “Compatible” is a looser term that indicates the
maximum safe writing speed according to the manufacturer.
“Recommended” is the Plextor-recommended speed for ensuring top-quality
writing using this media. Plextor tests media and enters the “compatible” and
“recommended” speeds into the drive’s media catalog.

For example, 8X-rated media listed as “12X writing recommended” and
“16X compatible” indicates the manufacturer believes this 8X-rated media
can be written at 16X. Plextor factory testing has determined you will
achieve the highest quality write at 12X. Plextor’s testing also indicates you
can write this media at 16X and still achieve good quality, although perhaps
not as high as at the recommended speed.

Just because the vendor rates a disc for a certain speed doesn't mean that the
disc will give you a high-quality write at that speed. However, the PoweRec
technology in your Plextor drive ensures you will write at the highest
possible speed that still achieves high quality.

Q: What are the transfer rates for the different interfaces?

A: Different interfaces have different maximum transfer rates. The following
table compares the transfer rates for the different interfaces.

Interface Maximum Transfer Rate

USB 2.0 (Hi-Speed) 480 Mbps max.

USB 1.1 (Full-Speed) 12 Mbps max.

IEEE 1394 (FireWire) 400 Mbps max.

Actual transfer rates in the real world depend on the type of media and
software you’re using, and on the type of data being transferred.

Recommended Media

Recommended media are recordable or rewritable CD and DVD media
that have been tested by Plextor. For the latest updated list of
recommended media for the PX-740UF, see the Plextor web site at
www.plextor.com

NOTE: For the media below:
Rated means the maximum write speed established by the media
vendor.

Recommended is the Plextor-recommended speed, which means that
testing by Plextor engineers indicates the media will achieve top quality
when written with the PX-740UF at that speed.

Compatible means the manufacturer indicates the disc can be written at
this higher-than-rated speed, although an increase in errors may occur.

PoweRec in the Plextor drive performs real-time monitoring of write
quality and adjusts the write speed up and down to ensure the best
quality possible.

Appendix B: Technical Support

Store Plextor’s e-mail, web site, phone, and fax numbers in a convenient
location. Keep your drive’s serial number and a copy of your sales
receipt handy as well.

If you experience a problem while installing or operating your drive,
please refer first to the relevant sections of this manual regarding setup
and installation (Sections 1–3). If you do not uncover the solution there,
please refer next to the maintenance and troubleshooting section that
begins on page 29. You may also wish to refer to the Frequently Asked
Questions (FAQ) section of our web site to assist you in troubleshooting
the problem on your own.

NOTE: We encourage you to go the Plextor web site (www.plextor.com)
before attempting to contact Technical Support. The answers to the most
common questions callers ask can be found quickly in the support area.
Select PlexHelper for online troubleshooting or FAQs for answers to
common questions.

If you have not been successful in your quest, our Technical Support
Department will help you solve problems that relate specifically to your
PX-740UF drive. In many cases, a problem that appears to be caused by
your Plextor drive actually originates in another part of your computer.
In such instances, our technical support staff will try to help you identify
the part at fault and will refer you to the manufacturer of that part for
further assistance.

Appendix B: Technical Support

Returns

In the unlikely event that you need to return a drive to Plextor, you need
an RMA (Returned Materials Authorization) number. You will need this
number before any Plextor drive can be returned for replacement. Here’s
how you get an RMA number and return your drive:

1. Contact Plextor Technical Support. You will receive assistance in

troubleshooting your system. If the drive is determined to be
defective, you will receive an RMA number.

2. Plextor will e-mail you with the RMA number and shipping

information.

3. When you receive the RMA number, pack the Plextor drive securely

in a box, and include the RMA number with the drive.

4. Write the RMA number in large bold numbers on the outside of the

box, and ship it to Plextor.

Contacting Plextor’s RMA Department

You can contact our RMA Department and request an RMA number at:

• [e-mail]

• Or by calling us at 1-800-204-0332 or 937-615-1610.

Packing Your Drive

Check the drive to make sure there is no disc inside, and if possible,
pack your drive in the original box. Some of our customers have not
held on to their boxes and have had to resort to less-than-secure methods
to get drives back to us.

Do not include the AC adapter when you ship the drive.

CAUTION: Never ship the drive with a CD or DVD disc inside it.

PX-740UF Installation and Users Manual 53

Appendix B: Technical Support

If you did not receive a box (for example, your drive came pre-installed
in a computer), we recommend you pay a packaging store (such as The
UPS Store) to ship your drive. If you don’t have a packaging store in
your area, ask for packaging pointers when you contact us to get an
RMA number before returning any drive.

Shipping Your Drive to Plextor

Be sure to write the RMA number on the outside of the shipping box.
Any drive sent to Plextor without an RMA number will not be accepted.

NOTE: The RMA number must be clearly visible on the outside of the
shipping box.

Drives must be sent postage prepaid. We recommend that you insure
your shipment, as Plextor cannot be held responsible for any damage
that may occur during shipment.
