Writing to DVD-RAM Discs (R200 only)
Handling DVD-RAM media
DVD media is sensitive to dust and fingerprints. Carefully handle media by its edges only.
If a DVD movie skips or hangs during playback, clean the media. Most DVD video
playback issues are media-related and can be remedied by proper handling and care of
media.
Cleaning Media
Try to avoid touching the read area (underside) of the disc as dirt and smears will
degrade the disc accessing speed.
If the disc becomes dirty, wipe it with a damp soft cloth. Avoid cleaning in a circular
motion, but rather from the inner side outward.
Formatting media
DVD-RAM media must be formatted before data can be written onto the disc.
There are two levels of formatting that are available when formatting DVD-RAM media:
Quick and Certified.
Quick formatting
Quick formatting is a rapid format - usually about 1 minute per disc. This prepares the
media for writing, but does not check the integrity of the media.
Certified formatting
Certified formatting is a low level, more comprehensive formatting. With Certified
formatting, each sector on the disc is checked, and any sectors that are found to be
unwritable are indexed. When a Certified disc is written to, those sectors are then
automatically skipped. This greatly increases the writing speed to these 'Certified' discs,
since the sector checking and indexing does not have to be done during the write
process.
PowerFile highly recommends that all discs be formatted with the certified format before
writing.
Note that formatting of media (Quick or Certified) will permanently
erase all data on that media.
