Introduction
Features of the CRW8424S Drive
8X Speed Writing to CD-R, 4X Speed Writing to CD-RW and 24X
Speed Reading
The CRW8424S drive can write to CD-R at 8X, 6X, 4X or 1X speed and
write/overwrite to CD-RW at 4X or 2X speed. It can also read from CD-R, CDRW and CD-ROM discs at up to 24X speed.
Supports a Wide Range of CD Formats
The CRW8424S drive can read from and write to CD-ROM in standard ISO9660
format and to audio CD in CD-DA format. Use the drive for a wide variety of
purposes, such as backing up data, writing your own audio CDs and creating
multimedia titles (using CD-Extra mode). Just choose the writing/reading
format that suits your needs. For more details, refer to page 4.
SCSI-3 (Ultra SCSI) Compatible
The CRW8424S is compatible with the SCSI-3 (Ultra SCSI) protocol for
interconnecting computers and peripherals.
Supports all Four CD Writing Modes
These modes are Disc-at-Once (the disc is written in a single pass without
pausing, as used for audio CDs and in premastering), Track-at-Once (data can be
written incrementally to disc one track at a time), Session-at-Once (each session
is written in a single pass without pausing), and Packet Writing (data can be
written to disc in small increments just like with a floppy or hard disk). For
more details, refer to page 35.
2
System Configuration
In order to use the CRW8424S drive, your computer system will need to meet
the following set of requirements.
Computer
The minimum system requirements for using the CRW8424S drive are as
follows:
● Any fully PC/AT-compatible computer.
● A Pentium-class or higher CPU running at 200MHz or faster.
● OS: Windows 95, Windows 98, Windows 98 SE (Second Edition) or
Windows NT4.0 with Service Pack 3/4/5.
● A vacant 5.25-inch drive bay for mounting the drive.
● A spare PCI expansion slot for a SCSI card (if one hasn’t been installed yet).
● A SCSI card to connect SCSI devices (including the CRW8424S) to your
computer. Make sure it has an internal bus connector. Yamaha recommends
any of Adaptec’s AHA-2940-series cards (PCI slot).
Software
The software requirements for using the CRW8424S drive are as follows:
● CD writing software. This software must support the CRW8424S drive for
writing to CD-R or CD-RW.
n For details about how to install and use the software, refer to the documentation that came
with it.
● When temporarily storing data on a hard disk prior to writing to CD-R/RW,
you will need an extra area of 50 ~ 100MB free hard disk space. When
creating an image file of the data on hard disk before writing to CD-R/RW,
you will need as much hard disk space as the original data, plus an extra 50
~ 100MB. However, this extra area is not needed when backing up directly
from CD-ROM.
n Data is written to disc much more reliably when writing from an image file, eliminating the
likelihood of errors occurring. Furthermore, this solution is ideal when making multiple
copies of discs since the original data is backed up to hard disk as an image file.
3
System Configuration
Discs
The CRW8424S drive is compatible with discs which meet the following
specifications:
● CD-R discs:
Use discs that conform to the Orange Book Part 2 standards. When writing
to CD-R at 6X or faster speed, you should use discs that have been designed
for high-speed recording.
● CD-RW discs:
Use discs that conform to the Orange Book Part 3 standards. When writing
to CD-RW at 4X speed, you should use discs that have been designed for
high-speed recording.
● Read-only discs:
You can read from any CD-ROM discs that conform to the Yellow Book
standard, and which bear the logo. You can also play back any CDDA (audio) discs that conform to the Red Book standards, and which bear
the logo.
n The Orange Book standard defines how all recordable discs (including CD-R and CD-RW) are
written. Part 2 of the Orange Book standard relates to CD-R discs and Part 3, to CD-RW discs.
The standard was named after the color of the book’s pages. Similarly, the Red Book standard
relates to audio (CD-DA) discs and the Yellow Book standard relates to CD-ROM discs.
About CD-ROM
A CD-ROM disc is a compact disc containing high-density read-only data. It
has many applications, including the playback of music and video, the
archiving of data, as well as on-line documentation. The following are
descriptions of each CD-ROM format:
CD-DA: Up to 74 minutes of stereo audio is written in 16-bit resolution at a
sampling rate of 44.1kHz (for a 74 minutes disc).
Data CD: Up to 650 megabytes of computer data is stored in standard
ISO9660 format.
Video-CD: These hold movies in which the video and audio data has been
compressed using MPEG-1 technology.

1 SCSI ID number
Each of the SCSI devices connected to the computer is identified by its SCSI ID
number. You need to assign a number from “0” to “7” for each SCSI device.
Commonly, ID number “7” is reserved for the computer’s SCSI adapter card
itself. Therefore, the CRW8424S can actually be assigned an ID number from
“0” to “6.” The ID number is set by attaching/detaching the shunts on the ID

n The SCSI ID number for each device on the chain must be unique. Make sure the CRW8424S
drive’s SCSI ID number is not the same as that of any other device on the chain. By factory
default, the CRW8424S is assigned ID number “3” but this can be changed.
n The CRW8424S is compliant with the SCAM Level 1 protocol. This means that if there is a
conflict between the manually-assigned SCSI ID of the drive and the ID of another SCSI device
on the same chain, the CRW8424S is automatically assigned an alternative vacant SCSI ID by
the Plug and Play component of Windows 95/98/NT4.0.

Installation
Installing the CRW8424S Drive
You can install the CRW8424S drive in one of two possible ways:
● As an additional drive
If the casing of your computer has a spare 5.25-inch drive bay available, such as
with many tower-type designs, you can fit the CRW8424S drive in addition to
the computer’s existing CD-ROM drive.
● As a replacement drive
If the casing of your computer does not have a spare 5.25-inch drive bay
available, such as with many desktop-type designs, you can replace the
computer’s existing CD-ROM drive with the CRW8424S drive.
n When replacing an IDE-type CD-ROM drive with the CRW8424S drive, you will also need a
SCSI adapter card and an internal SCSI flat cable.
13
Installation
Fitting the CRW8424S as an Additional Drive
1 Power down your computer and unplug it from the AC outlet.
If you proceed without doing this, you run the risk of receiving an
electric shock and/or short-circuiting and damaging components
including the CRW8424S drive.
2 Remove the outer casing of the computer. If you need to remove screws in
the process, make sure you don’t lose them.
n The method for removing the casing and fitting the drive in the drive bay can vary depending
on the manufacturer. Refer to the documentation that came with your computer for further
details.
14
Installation
3 Touch a metal part of the computer’s chassis or power supply unit to drain
any static charge that may have built up inside your body.
Drain any static charge
You can permanently damage equipment if you touch it while there is
any static charge in your body.
4 Remove the front cover of a vacant 5.25-inch drive bay slot in the computer
and slide the drive backwards into the slot.
n Do not apply excessive force when sliding the drive back into the drive bay slot.
15
Installation
5 Leave enough room behind the drive for connecting the power, SCSI and
audio cables. Then tighten the four fastening screws on the sides of the unit
by hand to hold the drive in place.
About SCSI adapter card termination
To connect internally-mounted SCSI devices, the SCSI adapter card’s onboard internal SCSI termination must be switched ON. With most cards,
this is done automatically. If your SCSI adapter card requires that you
manually disable internal termination, refer to the documentation that came
with it.

Troubleshooting
Please also refer to the YAMAHA CD-R/RW Drives web site for more
information.
YAMAHA CD-R/RW Drives web site URL:
http://www.yamaha.co.jp/english/product/computer/
The drive does not power up.
● Is the 4-pin power cable from the computer’s power supply attached correctly?
The computer does not start up.
● Is the SCSI card installed correctly? Please read the instructions that came with
your SCSI card for details.
The CRW8424S drive is not recognized.
● Is the 4-pin power cable from the computer’s power supply attached correctly,
and does the drive power up? Also, is the SCSI cable connected correctly?
If the system has started up normally, you will be able to see the CRW8424S drive
and SCSI card listed in Control Panel | System | Device Manager tab. The drive
will be listed when you double-click on CDROM and the SCSI card will be listed
when you double-click on SCSI controllers. (→P. 21, 29)
When you power up your computer, you can access the machine’s hardware SCSI
BIOS settings before Windows is loaded. You can set your computer to recognize
the SCSI card and CRW8424S drive in the BIOS.
n
Generally, the BIOS (Basic Input / Output System) is a small program that resides on a ROM chip
on the computer’s motherboard as well as on some expansion cards. It checks the system and its
devices (such as serial ports and hard disk controllers) before loading the operating system (OS).
● Are you using the correct SCSI driver?
If the SCSI card has not been installed correctly under Windows 95/98, make sure
that you have installed the most recent drivers supplied by the SCSI card
manufacturer.
If the SCSI card has not been installed correctly under Windows NT, update to
the most recent ASPI drivers supplied by the manufacturer of the SCSI card or
the CD-writing software.
For information about the latest version of any driver, please contact the
respective hardware/software manufacturers.
● Is the SCSI adapter card recognized correctly by the operating system (OS)?
The drivers for your SCSI adapter card may be incorrect. For more details,
contact the manufacturer of your SCSI adapter card.
● Is the drive’s SCSI ID number the same as that of another device on the SCSI
chain? (→P. 10)
● Are the pins and holes on the SCSI connectors straight and not deformed?
Check the connectors.
32
Troubleshooting
● Is the terminator on the CRW8424S drive set correctly?
It should be set to ON only if it is the last device on the SCSI chain. Otherwise,
it should be set to OFF. (→P. 11)
● Is the termination on the SCSI card set such that internal SCSI devices can be
connected?
Please read the instructions that came with your SCSI card for details.
● To write to CD-R/RW discs, your CD writing software must support the
CRW8424S drive.
To find out if it does, contact the manufacturer of your CD writing software.
The disc tray does not come out.
● Is the CRW8424S drive powered up?
● Some CD writing applications will lock the disc tray once loaded.
In which case, use the eject command from within the application. Alternatively,
read the manual that came with the application.
The disc keeps being ejected.
● Has the disc been placed on the disc tray correctly?
The drive does not operate correctly.
● Is the disc compatible with the CRW8424S drive?
n Even if the disc is of a type compatible with the CRW8424S drive, some varieties of discs can
still be unreadable on it.
● Is there dust on the disc tray or on the disc itself?
● Is the terminator of the last device on the SCSI chain set to “ON?” Or if it has no
built-in termination, has a terminator been attached?
● Does the computer have a sufficient power supply?
The CRW8424S has a power consumption of 11W (when reading and writing).
● Does your computer have several different CD writing applications installed?
If you use more than one CD writing application simultaneously, the behavior of
the drive can become unpredictable.
33
Troubleshooting
The drive ejects or fails to read the disc, or the ON/DISC LED
remains lit in orange after the disc has been loaded (meaning that
the disc has not been recognized). (→P. 38)
● Disconnect the SCSI cable from the drive but leave the power cable connected,
then load a disc.
● There may be problems with the disc itself. If the drive fails to recognize a
variety of discs including audio CDs, CD-ROMs and blank CD-R/RW discs (the
ON/DISC LED remains lit in orange after any discs have been inserted), you
should contact your nearest Yamaha dealer.
Errors occur when backing up at 6X or 8X speed from a separate
CD-ROM drive to the CRW8424S drive.
● A possible reason is that the CD-ROM drive is not suitable. Please use a high-
speed CD-ROM drive. However, for various possible reasons, you may still
encounter errors even if you are using a 32X or 42X speed CD-ROM drive.
Therefore, before writing directly at 6X or faster speed, you should check that it
is possible to do so by choosing to test before writing.
The “Buffer Underrun” error message is displayed.
● Try the following:
• Lower the writing speed setting.
• Create an image file of the CD on the computer’s hard disk.
• Defragment the hard disk.
• Turn hard disk power management off.
• Deactivate the Active Desktop (if you are using Internet Explorer 4 or 5).
• Disable network access.
• Close other applications (including screen savers, task schedulers, etc.).
n Errors can occur if you knock the CRW8424S drive while it is writing to disc.
n When using packet writing on a CD-RW disc, the actual data capacity is 100MB less than that
stated on the cover of the disc. The difference in capacity is dependent on the writing mode.
This mode is used when writing a complete disc in a single pass without
pausing. Data cannot be added later, even if the full capacity of the blank disc
has not been used.
n The lead-in and lead-out areas signify the beginning and end points of a session. They are not
part of the data but contain information about the session itself. Basically, a session consists of
a lead-in, data, and a lead-out.
Track-at-Once (TAO)
This mode is used when writing data to a disc one track at a time. More tracks
can be added later if there is enough space left on the disc. This is why Track-atOnce mode is sometimes referred to as Multisession.
n Only the first session of a multisession disc can be played back on a conventional audio CD
player. Single session discs can be played back completely.

Appendix
Session-at-Once (SAO)
This mode is used when writing each session in a single pass without pausing.
More sessions can be added later if there is enough space left on the disc.
n With CD-Extra, the audio is written in the first session and the data is written in the second.
A maximum of 99 tracks can be written.
Packet Writing
This mode is used when writing to a track of a disc using small blocks of data
called “packets,” in a manner similar to a floppy disk. This mode is useful when
making small incremental backups of data. You will need to use software which
specifically supports packet writing, such as Adaptec’s DirectCD.
n Discs must be formatted before they can be used for packet writing. With CD-RW, erased data
can be overwritten until the disc is completely full.
With CD-R, the space used by the erased data cannot be reused and is “masked” so that it is
no longer visible. This can be done up to 100 times.
