I'm fairly sure that you can successfully run "burncd fixate" just after running "burncd data ...", but I don't know what can be done in between without messing things up. I don't know if the drive has "memory" which gets used in the fixate process or if it's something that can be done from scratch at any time after burning the data. (I've even had occasional success restarting a burn that bailed out mid-CD. Sadly, I can't get my burner to burn or even mount CDs reliably lately. New kernel didn't help. Guess I'll have to install Linux and see if it can drive the thing any better.) When "analyzing" CDs, know that "burncd" usually puts an extra 2k block on the CD, so that a raw "diff" won't work. I think I've posted my CD-diffing script here already; ask me if you'd like it. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
