Operating Basics
■ If you add data to a DVD-R, DVD-R DL, DVD+R or DVD+R DL 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-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 DL, DVD-RW, DVD+R, DVD+R DL 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 DL, DVD-RW, DVD+R, DVD+R
DL 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,
DVD+RW disc.
