Thanks for the help but up to now I still have no success. The last commands I have used are mkisofs -r -J -o cd_image /home/cons/fotos followed by the command as root: cdrecord -v speed=1 dev=0,0,0 -data cdimage
From the several trials I ran one burning successful but I still could not mount the cdrom. All the other burning ended with a long error message:
cdrecord: input/output error. test unit ready: scsi sendcmd: retryable error CDB: 00 00 00 00 00 00 status: 0x0 (GOOD STATUS) this message is repeated some eight times, I think and the last lines are: CDB: 55 10 00 00 00 00 00 0010 00 status: 0x0 (GOOD STATUS) cdrecord: fifo had 279 puts and 216 gets cdrecord fifo was 0 times empty and 209 times full, min fill was 96% It takes quit a long time for all the error messages to finish after which I can use my computer again ;-(. Could somebody tell me what is going wrong with my burning?
