Description Dimitris 2006-05-24 19:22:35 EDT
Description of problem:

I'm using FC5 with all the latest updates. Unfortunately when i burn a DVD all i
end up with is a disk that contains garbage.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1) load Places->CD/DVD Creator
2) drag&drop some files (total 4gigs)
3) click on Write to Disc
4) select File Image, to create just the image first
5) click on Write to create the image

Actual results:

now, lets test the image...

#mount /tmp/image.iso /mnt/image -t iso9660 -o loop

as a result, we'll be able to browse the image we created under /mnt/image/.

so it worked under the loop device in linux... so now lets burn it...

#cdrecord -v -dao -eject driveropts=burnfree speed=48 dev=2,0,0 "image.iso"

the above command burns the image at my Plextor PX-716 (external USB2 dvd
writer), once that is done, we take the ejected DVD and insert it again on the
same drive or into another drive.

guess what... the DVD is unreadable, it contains garbage...

so what is this about? FC5 generates an image thats usable under the mount loop
device but it burns garbage?

Expected results:

the dvd should be readable.

Additional info:

Here is the cdrecord output.

# cdrecord -v -dao -eject driveropts=burnfree speed=48 dev=2,0,0 "image.iso"

Comment 1 Dimitris 2006-05-25 07:44:26 EDT
I believe i found what the problem/bug is.

Apparently, cdrecord shouldn't allow me to use -dao to burn DVDs.

Instead it should force me to use SAO only, since DAO burns garbage.

Since you are using 1 year old version of cdrecord, i downloaded the unmodified
cdrecord which was released 15 May 2006. I tested with the same commandline and
this newer version didn't allow me to burn with DAO, instead it complained that
i should use PACKET or SAO when burning DVDs.
Comment 2 Dimitris 2006-05-25 09:23:25 EDT
Well, apparently the cdrecord that comes with FC5 is broken.

It ALWAYS burns garbage.

I can't understand why people haven't reported this before, maybe its related to
Plextor dvd recorders.

The same commandline for FC5's cdrecord burns fine when used with the original
cdrecord. Any try to burn a DVD with the FC5 cdrecord results in a bad disk with
garbage on it (DVD is just unreadable).

Comment 3 Harald Hoyer 2006-05-29 08:28:43 EDT
It is related to Plextor drives... use growisofs...
Comment 4 Dimitris 2006-05-29 08:55:52 EDT
Well, apparently the cdrecord version included in FC5 is 1 year old!

I've opened a separate bug and requested the latest version of cdrecord to be
included, which also fixes all the Plextor related garbage that i've reported in
this bug, this growisofs isn't needed.

Thank you.
