■If the disc is poor in quality, or is dirty or damaged, writing or rewriting errors may be noted - ensure that you check all discs for dirt or damage before you use them.

■The actual number of rewrites to CD-RW, DVD-RW, DVD+RW or DVD-RAM media will be affected by the quality of the disc itself and the way in which it is used.

■There are two types of DVD-R media available, authoring discs and general use discs. Do not attempt to use authoring discs as only general use discs can be written to by a computer drive.

■You can use both DVD-RAM discs that can be removed from a cartridge and DVD-RAM discs designed without a cartridge.

■You may find that other computer DVD-ROM drives or other DVD players may not be able to read DVD-R, DVD-R (Dual Layer), DVD-RW, DVD+R, DVD+R (Double Layer) or DVD+RW discs.

■Data written to a CD-R, DVD-R, DVD-R (Dual Layer), DVD+R or DVD+R (Double Layer) discs cannot be deleted either in whole or in part.

■Data deleted/erased from a CD-RW, DVD-RW, DVD+RW or DVD-RAM disc cannot be recovered. You must check the content of the disc carefully before you delete it, making sure that if multiple drives that can write data to discs are connected, you do not delete data from the wrong one.

■In writing to DVD-R, DVD-R (Dual Layer), DVD-RW, DVD+R,

DVD+R (Double Layer), DVD+RW or DVD-RAM media, some space is required for file management, so you may not be able to write to 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 1GB. Therefore, in these circumstance, even if you write only a small amount of data, it might take additional time to fill in the dummy data.

■When multiple drives that can write data to discs are connected, be sure that you do not write to or delete data from the wrong drive.

■Be sure to connect the AC adaptor to the computer before you write or rewrite any information.

■Before you enter either Sleep Mode or Hibernation Mode, take care to ensure that any DVD-RAM writing has been completed. In this instance, writing is finished if you can eject the DVD-RAM media.

■Be sure to close all other software programs except for the writing software itself.

■Do not run software such as a screen saver which can put a heavy load on the processor.

■Operate the computer at its full power settings - do not use any power- saving features.

■Do not write information while virus checking software is running, instead wait for it to finish, then disable the virus protection applications, including any software that checks files automatically in the background.
