View Full Version : FC5 creates garbage DVD images

25th May 2006, 12:06 AM
I'm using FC5 with all the latest updates. Unfortunately when i burn a DVD all i end up with is a disc that contains garbage.

Here is my procedure:

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

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?

Any help would be appriciated.

cdrecord reported no errors, i even lowered the write speed.
