Operating Basics
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, taking care 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.
