Before Use

When the CRW-70 drive is connected to a computer and used as a CD-R/

RW drive, the system environments must satisfy the following conditions.

If your computer does not meet the requirements listed below, the CRW-70 

drive may not be able to write at the maximum speed.

Hardware

• PC/AT-compatible computer

• CPU: Pentium II-class or higher, 300 MHz or faster

• RAM: 64 MB or more

• USB port (USB 2.0 compatible)

• A spare PCI expansion slot or a CardBus slot for a USB interface card (if 

there is a need to install an USB interface card in your computer)

• CD-ROM  drive

• To install the device drivers, you need a CD-ROM drive other than the CRW-70 

drive.

• The CRW-70 drive cannot be used as a boot drive. Furthermore, the CRW-70 

drive cannot be used to set up the operating system one more time.

• For Windows XP, use a RAM of 128 MB or more.

USB interface card

Your computer requires a USB port in order to connect the CRW-70 drive. 

To fully utilize the performance of the CRW-70 drive, a USB 2.0 compatible 

interface card and EHCI (Enhanced Host Controller Interface) compliant 

driver are also necessary. If your computer has a USB port with USB 1.1 

specifications, YAMAHA recommend that you install a USB 2.0 compatible 

interface card.

• For the latest information about USB 2.0 interface cards already checked for 

compatibility with your drive, go to the YAMAHA CD-R/RW Drive web site.

interface card, or information about the operating system supporting the card, go 

to the interface card manufacturer’s web site or contact user support services.
