The COPY/RECORDABLE_MEDIA command records the entire contents of the specified input disk image file or input device onto the media loaded into the specified output CD or DVD recording device. The output media format is sensed automatically, and the utility automatically configures the recording appropriately for the particular target device and for the output media that are loaded. You cannot record more than the capacity of the target media permits. Therefore, you need to select the size of the input disk image or the master appropriate for the capacity of the target media. The input data source must also be an even multiple of the sector size on optical media; the size of the input must be a multiple of four blocks. The recording operation is independent of the input volume structure or input file data used for the master, and is based solely on the block-level contents of the specified input master.
