Owner's Manual

No data can be read from any CDs, a disc is ejected spontaneously, or the

status LED does not light when a disc is inserted. (The LED does not change

to blinking blue and then lighting blue.) (P. 3)

Disconnect all cables 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

status LED does not light), contact the store of purchase or your nearest Yamaha

dealer (listed at the back of this manual).

The error message “Buffer Underrun” is displayed.

If your CD writing software supports Buffer Underrun Protection, it is required to be

activated. For details, refer to the instruction for the 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 instruction for it.

• If there is an IEEE1394 device with lower data transfer speed connected between the

computer and the CRW-F1DX drive, the data transfer between those two will be

slowed, which may cause failure in writing a disc.

• When the CRW-F1DX 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 to 8X for a CD-R disc

or 10X for a CD-RW disc with the writing software. (P. 13)

• A writing error may happen if the drive is vibrated while data is being written on a

CD-R or a CD-RW disc.
