Operating Basics

If the disc is poor in quality, dirty or damaged, writing or rewriting errors

may occur.Be careful to check the disc for dirt or damage before you

use it.

The actual number of rewrites to CD-RW, DVD-RW, DVD+RW or

DVD-RAM is affected by the quality of the disc and the way it is used.

There are two types of DVD-R discs: authoring and general use discs.

Do not use authoring discs. Only general use discs can be written to by

a computer drive.

You can use DVD-RAM discs that can be removed from a cartridge and

DVD-RAM discs designed without a cartridge.

Other DVD-ROM drives for computers or other DVD players may not be

able to read DVD-R/-RW or DVD+R/+RW discs.

Data written to a CD-R/DVD-R/DVD+R disc cannot be deleted either in

whole or in part.

Data deleted (erased) from a CD-RW, DVD-RW, DVD+RW and

DVD-RAM disc cannot be recovered. Check the content of the disc

carefully before you delete it. If multiple drives that can write data to

discs are connected, be careful not to delete data from the wrong drive.

In writing to a DVD-R/-RW, DVD+R/+RW or DVD-RAM disc, some disc

space is required for file management, so you may not be able to write

the full capacity of the disc.

Since the disc is based on the DVD standard, it might be filled with

dummy data if the written data is less than about 1 GB. Even if you write

only a small amount of data, it might take time to fill in the dummy data.

DVD-RAM formatted by FAT32 cannot be read in Windows 2000

without DVD-RAM Driver Software.

When multiple drives that can write data to discs are connected, be

careful not to write to the wrong drive.

Be sure to connect the AC adaptor before you write or rewrite.

Before you enter standby/hibernation mode, be sure to finish DVD-RAM

writing. Writing is finished if you can eject DVD-RAM media.

Be sure to close all other software programs except the writing

software.

Do not run software such as a screen saver, which can put a heavy load

on the CPU.

Operate the computer in the full-power mode. Do not use power-saving

features.

Do not write while virus check software is running. Wait for it to finish

and then disable virus detection programs including any software that

checks files automatically in the background.

Do not use hard disk utilities, including those intended to enhance hard

disk drive access speed. They may cause unstable operation and data

damage.

This drive cannot use discs that allow writing faster than 8 speed (DVD-R,

DVD+R),4 speed (DVD-RW,DVD+RW),5 speed (DVD-RAM)
