You might not be able to use the DISC backup function of Drag'n Drop
CD+DVD to back up a DVD-R/-RW or DVD+R/+RW disc that was made
with other software on a different DVD-R/-RW or DVD+R/+RW recorder.

If you add data to a DVD-R disc that you have already recorded to, you
might not be able to read the added data under some circumstances. It
cannot be read in 16-bit operating systems, such as Windows 98SE and
Windows ME. In Windows NT4, you will need Service Pack 6 or later to
read added data. In Windows 2000, you will need Service Pack 2 or later
to read it. Some DVD-ROM and CD-RW/DVD-ROM drives cannot read
added data regardless of the operating system.
■
Drag'n Drop CD+DVD does not support recording to DVD-RAM discs.
To record to a DVD-RAM, use Explorer or other utility.
■
If you try to back up a DVD disc to a DVD-RW disc that was erased by
the Quick erase option, you might get an error message. Use the Full
erase option to clear the DVD-RW disc and try again.
■
When you back up a DVD disc, be sure the source drive supports
recording to DVD±R/±RW discs. If the source drive does not support
recording to DVD±R/±RW discs, it might not be backed up correctly.
■
When you back up a DVD-R, DVD-RW, DVD+R or DVD+RW, be sure to
use the same type of disc.
