10.2. Erase a Disc
Nero Express can be used to erase rewritable discs, i.e. discs with the RW specification, as
long as your recorder supports this feature. Two erase methods are available for this
purpose:
Quick erasing does not remove the data physically from the disc, but instead only makes
it inaccessible by erasing the references to existing content. The data can be restored!
Full erasing removes the data from the disc by overwriting it with zeros. The contents
cannot be restored with conventional methods. Repeated full erasing increases the
probability that third parties will not be able to reconstruct the contents.
The following configuration options are available in the Erase Rewritable Disc window:
Selection list

Selection list
Select the erase
method to be used
Defines the erase method. Two options are available:
The Quick-erase rewritable disc method does not physically erase
all data from the disc, but only the references to the contents. The
disc will appear to be empty even though the data is still physically
available. Erasing a disc using this method takes between one and
two minutes.
The Full-erase rewritable disc method physically erases all data
from the disc. The contents cannot be restored with conventional
methods. Repeated full erasing increases the probability that third
parties will not be able to reconstruct the contents. Erasing the disc
using this method takes longer than the other method, depending
on the type of disc involved.
