Why or why recording just hung half-way and most mysteriously failed with "INVALID ADDRESS FOR WRITE" after a long while... Is there a chance that the drive was opened by another program during failed recording? No, I am quite sure that did not happen. The only user programs running during the backup were an editor and latex. I can't think of any daemons that would access /dev/dvd. I don't think that updatedb ran and even then I don't think that it would open /dev/dvd. *But*... I occasionally mount a dvd to check it contents, and then forget to umount it before rewriting it. I cannot be certain that I didn't do that on this occasion. growisofs does unmount media prior recording. If it fails to, it won't start the recording. So you can keep forgetting to unmount it:-), but you shouldn't "stand" in it (I mean if you cd /mnt/dvd, then attempt to unmount /mnt/dvd fails with "resource busy," and recording won't start). That is a great feature. Have never had a problem with that, but I can see that many new systems I install do seem to have a daemon which mounts media and resists all efforts to permanently kill and deconfigure it. It seems someone can't understand that you may not want to have that happen. -- bill davidsen <[EMAIL PROTECTED]> CTO TMR Associates, Inc Doing interesting things with small computers since 1979
