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. The CRW6416S drive supports sequential
(contiguous) and random (non-contiguous) packet writing.
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.
About the firmware
The “firmware” is a small piece of software built into the CRW6416S drive, and is
used to control its basic operation. Since it resides in flash memory, it can be
overwritten and updated.
To ensure the correct operation of the CRW6416S drive, updates to the firmware will
be made available. You can find information about the most recent firmware for the
drive on Yamaha’s web site.

The most recent user support information, including firmware updates, can be found
in the CD-R area of Yamaha’s web site. Please check this information regularly.
n
The firmware is completely unrelated to the CD writing application software.
