14 ULEAD DVD DISCRECORDER USER GUIDE
Edit Disc
Edit Disc lets you modify the existing DVD-VR content on a DVD-RW or DVD-RAM
disc. You can also format, protect, or certify a disc (also available on the
Preview
and Finish
page).
Formatting a disc
A DVD-VR disc must be formatted using the UDF (Universal Disc Format) 2.0
format for rewritable discs. To format a disc, click
and then click
OK
to
start.
Protecting a disc
To ensure that all the existing DVD-VR content on a disc cannot be changed or
removed, you can click
Protect Disc
to toggle between protected and unprotected
modes. When a disc is protected, only playback is allowed.
Certifying a disc
For a UDF 2.0 formatted DVD-RW disc, you can apply disc certification to scan the
disc and check if there is any problem. The certification process marks bad sectors
to improve future writing reliability. On DVD-RW burners that support DRT-DM
(Distributed Real-Time Defect Management), the certification process also moves
the data in the recoverable defected sectors (DRT-DM Level-1 and Level-2 defects,
if any) to healthy sectors to further improve data reliability.
To certify a disc, click
and then click
Start
.
Note:
Format Disc is also available on the Straight to Disc page.
