The Erase Disc feature lets you erase data from rewritable discs. This operation is run in the Nero DiscSpeed – Erase window. As a general rule, there are two erase methods available:
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 zeroes. 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.   
To erase a rewritable disc, proceed as follows:
1.
If there are several optical drives available, select the one you want in the drop-down menu.
