Operating Basics
If you add data to a DVD-R, DVD-R (Dual Layer), DVD+R or DVD+R
(Double Layer) disc that you have already recorded to, you might not be
able to read the added data under some circumstances. For example, it
cannot be read under 16-bit operating systems, such as Windows 98SE
and Windows Me, while in Windows NT4 you will need Service Pack 6
or later, and in Windows 2000, you will need Service Pack 2. In addition
to this, some DVD-ROM and DVD-ROM / CD-R/RW drives cannot read
this added data regardless of the operating system.
TOSHIBA Disc Creator does not support recording to DVD-RAM discs -
to achieve this you should use Windows Explorer or another similar
utility.
When you back up a DVD disc, be sure that the source drive supports
recording to DVD-R, DVD-R (Dual Layer), DVD-RW, DVD+R, DVD+R
(Double Layer) or DVD+RW media - if this is not the case then the
source disc might not be backed up correctly.
When you back up a DVD-R, DVD-R (Dual Layer), DVD-RW, DVD+R,
DVD+R (Double Layer) or DVD+RW disc, be sure to use the same type
of disc.
You cannot partially delete any data written to a CD-RW, DVD-RW or
DVD+RW disc.
