Nero Express

Selection list Source drive	Defines the drive from which the source information is read. Insert the CD or DVD that you want to copy into the drive.
Selection list Destination drive	Creates the destination drive. Insert a blank disc into this drive.
Button Info	Opens the Recorder Information window. This contains information on the selected destination drive.
Check box Quick Copy	Enables direct copying from the source to the destination drive. Data is not buffered on the hard drive during this process. The option On-the-fly is only available if there are at least two drives connected (does not apply for Nero Image Recorder). If this check box is not selected, an image file will be created first, which is then burned.
Selection list Write speed	Defines the speed at which the disc is burned. Only the burn speeds that are supported by the selected recorder are displayed. Not available for Nero Image Recorder.
Input field Number of copies	Defines the number of copies you require.
Check box Verify data on disc after burning	Verifies whether the burned data is identical to the original data. Not available for Nero Image Recorder.
Button Image file	Defines the folder where the image file is stored. You can change the name of the image file and target folder. Not available for Nero Image Recorder.

Check box Read all subchannel data	Reads all subchannel data during copying. Subchannel data is used to save additional information, e.g. CD Text or the lyrics of a karaoke CD. Select this check box when copying an Audio CD or a karaoke CD. The burner has to be capable of reading all the subchannel data.
Check box Determine maximum speed	Finds out the maximum burn speed. Not available for Nero Image Recorder.
Check box Simulation	Performs all steps in the burn process without using the laser beam. You can assume that if simulation is successful, the burn process will also be successful. Not available for Nero Image Recorder.
Check box Write	Starts the actual physical burn process (e.g. after a simulation). This check box is selected by default.

On-the-fly

On-the-fly refers to a method for copying to a disc. The data is transferred directly from the original storage location to the disc to be burned. To do this, Nero uses a compilation, a small file that simply refers to the transferred data.
