DVD+RW Disc Format is an utility included in the folder where the HP DVD Writer applications are installed.
This utility completely erases DVD+RW media by writing zeros in all the disc surface. This way, erased media is totally cleaned from content and possible logical errors.
Since complete formats take a long time (20-40 minutes depending on the media), this utility allows to stop current formats and continue them later.
note:
The DVD+RW Disc Format Utility does not return the disc to a blank new state. In addition, it is recommended to use the Erase tool included in RecordNow, because it is significantly faster than the DVD+RW Disc Format Utility.
