k3b lies, when real writtes to DVD-R(W) in simulate mode
Last modified: 2006-02-28 14:31:32 UTC
K3b broke my DVD-R when I canceled simulation of DVD-R in burning DVD iso image. In debugging output I found following command where is missing -dry-run option when start simulate mode. see: growisofs command: ----------------------- /usr/bin/growisofs -Z /dev/hda=/tmp/kde-postadal/k3b_image.img -use-the-force-luke=notray -use-the-force-luke=tty -use-the-force-luke=dummy -dvd-compat -speed=1 How reproduce it: prepare dvd iso image and some "empty" DVD-R(W) menu->tools->Burn DVD ISO Image... check Simulate box click start wait a minute and click cancel and see what happen with medium ;) And same result is from burning dvd data project: growisofs command: ----------------------- /usr/bin/growisofs -Z /dev/hda=/dev/fd/0 -use-the-force-luke=notray -use-the-force-luke=tty -use-the-force-luke=tracksize:17579 -use-the-force-luke=dummy -dvd-compat -speed=2
that looks more severe than major. Lubos, do you have a DVD-R(W) drive handy in prague?
From the what's this help for the simulate checkbox: "Caution: DVD+R(W) does not support simulated writing." So this may be a feature. I'll mail the authors.
But the problem is with DVD-R(W).
the whatsthis help isn't really the best place for such a warning anyway ;(
Nevermind, I mixed +'s and -'s . However, I've just successfully simulated burning on a DVD-RW media (in a combined drive though). According to the k3b source the option that turns on simulation should be -use-the-force-luke=dummy, which is included in the above-pasted commands (and http://www.justlinux.com/forum/showthread.php?threadid=138059 says that it's "Engage "Test Write" mode defined for DVD-R and DVD-RW Sequential."). So this is either growisofs bug or a problem with the drive/media/whatever, but it's unlikely it's k3b (and k3b BTW actually does warn in cases like trying to simulate writing with DVD+RW). Petr says that his drive seems to cause some other trouble and that it's okay to close this.
