From [EMAIL PROTECTED] Wed Nov 26 12:55:59 2003 His problems are caused by the fact that he did not read README.verify and README.copy. Probably it isn't cdrecord's fault since a readcd -c2scan shows a perfect CD. Now I have disabled DMA for the Plextor drive and now these errors have gone. So it must be related to Plextor+Linux+DMA . On my private PC at home (a newer Plextor 48x) I cannot access the drive at all when DMA is enabled (even a simple 'mount' of an ISO filesystem hangs) and the kernel log tells about a DMA timeout error. (The kernel is a recent 2.4.23-rc?) Sou you most likely use a Motherboard with a VIA KT133A chipset.
