46 ULEAD BURN.NOW USER GUIDE
•
Quick format
- Provides a fast way of reformatting a CD-RW
that has previously been full formatted. It simply removes the
file system table from the disc without checking for defects (that
is, bad sectors) and writes the selected UDF file system to the
disc.
Burn.Now provides only the
Quick format
option for DVD+RW
and DVD-RW discs. These types of discs do not require full
formatting, since in the process of writing data to these discs,
they are also simultaneously formatted.
•
Full format
- Completely formats a CD-RW using the selected
UDF file system, and writes new tracks and sectors onto the
disc. This formatting method takes a longer time to complete,
but it makes the disc error-free.
UDF Certify
For a UDF formatted DVD-RW and CD-RW, 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 and CD-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 for
further improvement in data reliability.
