Destination - Device
The erase button will allow you to erase the disc if it's desired. ImgBurn will ask you which type of erase it should perform.
If the +RW/BD media has not been previously formatted or is in the need for a full erase the 'Quick' option is disabled. A proper erased/formatted +RW media can then just be overwritten the next time you write to it without the need to first do an erase. -RW media always needs at least a quick erase before a new writing.
Quick
This is the fastest of the two modes as the deleting will be done by writing zeros to the first 800 sectors.
Full
ImgBurn will write zeros to the full disc. This erase will take the same amount of time as it will take for a regular writing to the media at MAX speed.
