The problem is in verifying the image. The error message is "unable to Fixate the disk, cdrecord has no permission to open disk, You may use K3Bsetup to solve the problem." This is occurring while trying to burn Gparted live 0.16.1-1 amd64.iso to a DVD-R using 3x speed all other setting are set to auto and verify is checked. MD5sums were verified correct for the image. Now to confuse us, in further testing I am able to burn this image to a CD, no problem. I am also able to burn other similar sized iso's to DVD and other Distro sized iso's to DVD. This behavior has me totally confused. This is occuring on NetrunnerOS 13.06 updated using KDE version 4.11.1. This install was on a reformated disk, only Home partition data was brought over from backup no .kde files were copied over.

can you look at the log ~/.kde/share/apps/k3b/lastlog.log there should be listed the actual command causing this error

the other dvd's you were able to burn iso's with were also dvd-r?

The tail end oi the log:

Hope this helps.

Immediately after performing that burn - where the fixation fails - can you check dmesg to see if any hardware related errors are printed?

I looked thru dmesg after the fail but nothing stood out. So I have posted the entire file on drop box. Here is the link:

Thank you for your help.

It appears that your optical drive fails to respond to the system when instructed to commence fixation of the disk, as evidenced by this dmesg output:

This results in the kernel resetting the link - ultimately causing the fixation (and burn) to fail. Unfortunately, i'm not aware of any measures that can be taken to mitigate this - you need to report this to your distribution kernel team, so they can investigate further.

Please include information on your hardware - particularly the optical drive in use in your report to them.

Thank you for your reply. I will certianly bring this up to the developers of my Distribution. The odd thing is that this error only occurs while trying to burn the gparted iso with verified md5sum to a DVD, burtning it to a cdrom works correctly, and other iso's both Distribution size and small gparted sized work on both types of media. Just donot understand what is going on. The is way above my troubleshooting correctional abilities. Thanks for your help.

Not a problem. I suspect it may be a corner case bug which the GParted ISO image only triggers with certain types of media, or it could be a bug in the firmware of your DVD drive.
