This is often due to a faulty CD/DVD disk or drive. It may help to clean the CD/DVD, to burn the CD/DVD at a lower speed, or to clean the CD/DVD drive lens (cleaning kits are often available from electronics suppliers).
Dit is meestal die gevolg van 'n foutiewe CD/DVD-skyf of aandrywer. Dit kan help om die CD/DVD skoon te maak, die CD/DVD teen 'n laer spoed te sny of om die CD/DVD-aandrywerlens skoon te maak (skoonmaakprodukte is gewoonlik beskikbaar by elektronikawinkels).
