Your problem is not a problem with cderecord but either caused by your usage or caused by another (hostile) program on Linux. Because Linux comes with competing drivers for CD-ROMs that partially do not implement working or useful DMA, it is a really bad idea to force cdrecord to use the unsupported dev=/dev/* syntax. Either fully remove the dev= parameter (in case you have only one CD-ROM drive in the system) or use the SCSI CAM standard conforming dev=b,t,l syntax. This allows libscg to select the best driver which is usually /dev/sg*, so make sure that your system has /dev/sg* available. The error message is either caused by non-working DMA or by a hostile program that disregards the rules for accessing CD-ROM drives that may be written to. The first hostile program that was known to interrupt CD-ROM writing is "hald" but later the same defective code has been moved to "udev" or to "systemd". If using the officially supported dev=b,t,l syntax does not help, you need to kill the program that incorporates the defective and hostile code. As you might not use "hald", you would need to get help from other people to learn which program you need to kill. http://www.fokus.fraunhofer.de/usr/schilling ftp://ftp.berlios.de/pub/schily ------------------------------------------------------------------------------ _______________________________________________ Cdrtools-support mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/cdrtools-support
