No data can be read from any CDs, a disc is ejected spontaneously, or
the LED remains purple when a disc is inserted. (The LED does not change
from lighting purple to blinking blue and then lighting blue.) (P. 3)
Disconnect the USB cable from your drive while the AC adapter is connected.
Insert the disc once again. If a specific disc is automatically ejected or cannot be
read, the disc itself may have a problem. If the drive does not accept any
compatible discs (and the LED remains purple), contact the store of purchase or
your nearest Yamaha dealer (listed at the back of this manual).

The error message “Buffer Underrun” is shown.
If your CD writing software supports Buffer Underrun Protection, you must
activate it. For details, refer to the documentation that comes with your CD
writing software.
To prevent the occurrence of a buffer underrun and to increase the efficiency of
data writing, try the following:
– Reduce the data writing speed.
– Create an image file on the hard drive.
– Optimize the hard drive. (Defragmentation)
– Do not start any application software including screen savers during data
writing.
– Deactivate the power management for the hard drive.
– Set the data transfer mode of any IDE device such as a hard drive or CD-
ROM drive to “DMA.”
– Deactivate Windows Active Desktop.
– Quit all memory-resident software programs.
– Check your CD writing software settings with the documentation that comes
with it.
• When the CRW3200UX drive is connected to a USB 1.1-compliant port on the
computer, the drive operates with USB 1.1 specifications. For secure data
writing, activate Buffer Underrun Protection and set the writing speed with the
writing software to 8X. (P. 9)
• A writing error may happen if the drive is vibrated while data is being written on
a CD-R or a CD-RW disc.
