Verify that you are using the correct disc type when making a copy of a disc. Some recording programs can record only to the same disc type as the source. For example, you can record a DVD only to a DVD+R/–R or a DVD+RW/–RW disc, and you can record a CD only to a CD-R or a CD-RW disc. Make sure the disc is in the correct drive and you specify the same drive in the CD or DVD recording software. Select a slower write speed for the recording drive, if it is available. The recording software may not let you add a track if it exceeds the available space on your disc. You can make space available by removing one or more tracks from the list before recording the files to disc. Close all software programs and windows before recording. Make sure you have enough space available on your hard disk drive to store a temporary copy of the content. If you are on a network, copy the files from a network drive to your hard disk drive first, and then record them to disc. Close all programs and windows and then restart your PC.
