One user of dvd+rw-tools reported that his burner was returning a 0xF sense code (which is reserved and presumably not actually being set by the device) under 5.x: brueffer@cheops:~ # growisofs -Z /dev/cd1 -R -J /mnt/disc4/some/files Executing 'mkisofs -R -J /mnt/disc4/some/files | builtin_dd of=/dev/pass1 obs=32k seek=0' [deleted list of files] /dev/pass1: "Current Write Speed" is 2.0x1385KBps. :-[ LBA=0h, SENSE KEY=Fh/ASC=FFh/ASCQ=FFh ] :-[ attempt -blank=full or re-run with -dvd-compat -dvd-compat to engage DAO ] :-( write failed: Input/output error Anyway, congratulations on looking into the problem you mentioned above and getting results. I'll submit a PR to update the port to 5.15.4.8.5. Happy holidays... -- -Chuck
