Can I use the "Disc Copy" function with only one drive / burner on my PC?

Yes. "Disc Copy" supports one or two optical drives. If the source drive (reader) and destination drive (writer) are the same, Power2Go will read all data from the source disc and generate an image file to store on the hard disc. Power2Go will automatically ask you to insert a writable optical disc into the drive (burner) when it is ready.
