Features
The ASUS CRW-4816A is a CD-RW drive with 48X-write, 16X-rewrite, and
48X-read capabilities. The drive complies with the AT Attachment Packet
Interface (ATAPI) specification and comes equipped with the latest
innovative technologies in CD recording.
Highlighting the major characteristic of ASUS CD-RW drives, the
CRW-4816A strategically identifies the media quality at the beginning of
the recording so that it can apply the appropriate writing speeds and
ensure effective data storage. Thanks to the FlextraSpeed™ and
FlextraLink™ technologies developed by ASUS.
FlextraSpeed™ increases accuracy and reliability when rewriting across a
broad base of certified media, while FlextraLink™ prevents buffer
underrrun problems to eliminate the creation of unusable discs. The
following sub-sections describe these technologies in detail.
FlextraSpeed™ Technology
The ASUS FlextraSpeed™ technology provides the optimum solution to
ensure quality recording when using discs that require flexible speeds. The
CRW-4816A drive employs this technology that allows automatic recording
speed adjustment based on the recording media.
In addition to the fact that there are low and high quality recording media,
various other factors such as dye layer, temperature, humidity, dust,
fingerprints, etc., affect the recording characteristics of CD-R and CD-RW
discs. Due to these factors, some discs may not be able to stand the highspeed capabilities of the latest CD-RW drives. The FlextraSpeed™
technology solves this problem by automatic assessment of the disc
quality and recording capability. The recording speed is based on these
factors. If you use a high quality recording disc, you can maximize the
recording capability of the drive and get the best quality output. If you use
a low quality disc, the drive speed adjusts to the level that is most
appropriate for the disc, still optimizing the disc recording capability.
The FlextraSpeed™ technology also helps maintain the CD-RW drive
because of the controlled motor rotation speeds and reduced noise
caused by spindle air, thus prolonging the drive motor’s life and ensuring
high-quality recording.

ASUS CRW-4816A User’s Manual
FlextraLink™ Technology
The ASUS FlextraLink™ technology provides a seamless combination of
flexibility and ultra-reliable recording quality.
FlextraLink™ incorporates a flexible strategy that prevents buffer underrun
problems caused by an empty data buffer. This CD-RW drive technology
allows continuous monitoring of the data buffer status during the write
process. Once the available data drops to approximately 1% of the total
buffer capacity, the drive stops recording and marks the last write position.
When new data is received from the host, it is loaded to the data buffer,
and the laser is repositioned to link the new data with the data already
written. FlextraLink™ uses minimal system resources so that your PC
remains fully operational throughout the writing process, and available for
other applications.
The diagram below shows the advantage of the FlextraLink™ recording
technology.

Double Dynamic Suspension System (DDSS II)
The DDSS II is an enhanced follow up to the DDSS anti-vibration system
developed by ASUS. The DDSS CD-ROM technology is designed to
reduce the vibration generated from spindle rotation of over 8900 rpm of
40X CD-ROM drives. The DDSS II improves this feature by handling up to
over 10,000 rpm of the new 50X drives. In addition, the DDSS II stabilizes
the pick-up head of the drive in both horizontal and vertical directions,
making tracking and focusing even more precise.
Like the DDSS, the DDSS II vibration absoption structure contains a
“dynamic mass” that can absorb the vibration caused by high revolution of
spindle motor. However, the DDSS II moves the dynamic mass to be
suspended to the chassis, thus providing more stability and accuracy
when accessing data from the disc.
The following diagram illustrates the DDSS/DDSS II design structure.

Partial Constant Angular Velocity (P-CAV) Recording Technology
The Partial Constant Angular Velocity (P-CAV) recording method is a
combination of the Constant Angular Velocity (CAV) and Constant Linear
Velocity (CLV) recording technologies. In CAV recording technology, the
drive maintains a consistent rotation speed which will result in a variable
transfer rate, while in CLV recording technology, the data transfer rate is
kept at a fixed level by changing the rotation speed.
P-CAV recording technology switches from CAV to CLV once the
maximum transfer rate is reached. Unlike Zone Constant Linear Velocity
(Z-CLV) recording, no links are produced in the P-CAV recording process,
resulting in a higher average transfer rate.
The following illustration compares the Partial Constant Angular
Velocity (P-CAV) and Zone Constant Linear Velocity (Z-CLV) recording
technologies.

Setting the Jumper Terminals
Configure the the jumpers to set the device to master or slave mode
before physically installing it to your computer chassis. Use jumper blocks
to short the pins to your desired setting.
CAUTION: Make sure to correctly place the jumper blocks over the
pins. Failure to do so may cause irreparable damage to the drive!
Jumper
Terminals
Master Mode
Cover the two pins labeled MASTER to set the CD-RW
drive as a secondary master drive. This is possible only if
your computer supports four IDE devices. The hard disk in
the computer is set as Primary Master.
Slave Mode
Cover the two pins labeled SLAVE to set the CD-RW drive
as a slave device if your computer supports only two IDE
devices.
If your computer supports four IDE devices, this setting
sets your CD-RW drive either as a Primary Slave or a
Secondary Slave.
Cable Select Mode
Cover the two pins labeled CABLE SELECT if your
computer supports a Cable Select (CSEL) signal. You
need an exclusive interface cable for this setting. Refer to
your computer manual for details.

Installing the CD-RW Drive
Follow these steps to install the drive into the computer chassis.
NOTE: Refer to your computer manual for specific instructions on
opening the chassis and installing drives.
1. Remove the cover of an empty 5.25-inch external drive bay.
2. Carefully insert the CD-RW drive into the bay and push it inward until it
is flushed to the chassis front panel. The holes on the sides of the drive
should align with the holes on the drive bay.

3. Secure the drive with screws that came with the drive package. Use
two screws on each side of the drive.
IMPORTANT: Depending on the space on your chassis, you may
need to connect the drive cables before securing the drive into the
chassis. For cable connections, proceed to the following section,
“Connecting the Drive Cables.”
ASUS CRW-4816A User’s Manual
19
Connecting the Drive Cables
1. Connect the power cable plug to the power connector on the rear
panel.
2. Connect the 40-pin IDE cable plug to the IDE connector, matching the
red pin stripe on the cable with Pin 1 on the connector.
3. If your computer has a sound card or an onboard audio feature,
connect an audio interface cable to the 4-pin analog audio connector
on the rear of the drive. Connect the other end of the audio cable to the
connector on the sound card or on the 4-pin CD connector on the
motherboard.
CAUTION! All the cable plugs are slotted so that they fit in only one
orientation. If a plug does not fit in completely, try reversing it. DO
NOT use too much force when fitting the cable plugs.
