If not, do it again with "of=/dev/null". one thing that we forgot to mention, is that if we use burncd with the fixate option, at the end of the write (both when using -t to test and when doing a real write), we get an IO error (something about IOCLOSECD). If we don't use fixate, we don't get the error, but then the CD won't mount anywhere either. Attempting to mount a cd after writing it has caused page faults and subsequent reboots on all three attempts now. -Wayne -- The time for action is passed. | wayne@penguinpowered.org.uk Now is the time for sensless | www.penguinpowered.org.uk bickering. | To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
