Check with hdparm /dev/hdc if your burner is named hdc. If it isn't on, try this: hdparm -d1 /dev/hdc and see if it helps. If you can't turn DMA on, you might not have support for your IDE controller in your kernel.
Thanks, Mogens. The result of your suggestion was: # /sbin/hdparm /dev/dvd /dev/dvd: IO_support = 0 (default 16-bit) unmaskirq = 1 (on) using_dma = 0 (off) keepsettings = 0 (off) readonly = 0 (off) readahead = 256 (on) HDIO_GETGEO failed: Inappropriate ioctl for device # What can I do now?
