■
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.
■
Do not use any hard disk utilities, including those that are intended to
enhance hard disk drive access speeds, as they may cause unstable
operation and damage data.
■
CD-RW (Ultra Speed +) media should not be used as data may be lost
or damaged.
■
You should always write from the computer’s hard disk drive onto the
CD/DVD - do not try to write from shared devices such as a server or
any other network device.
■
Writing with software other than TOSHIBA Disc Creator has not been
confirmed, therefore operation with other software applications cannot
be guaranteed.

CD-RW, DVD-R, DVD-R (Dual Layer), DVD-RW, DVD+R, DVD+R (Double
