k3b failing on a dual-layer disk.

[DaveQB]

I have 5 coasters here from trying to burn dual-layer iso images with k3b that were produced from devede app.

It seems to fail at around the 4GB mark. I have 3 log files of these fails, I have attached the most recent.

The main part seems to be this:

Track 01: 4076 of 4590 MB written (fifo 100%) [buf 3%] 0.0x.
Errno: 5 (Input/output error), write_g1 scsi sendcmd: no error

Sense flags: Blk 0 (not valid)
cmd finished after 0.015s timeout 200s
/usr/bin/wodim: The current problem looks like a buffer underrun.
/usr/bin/wodim: Try to use 'driveropts=burnfree'.
/usr/bin/wodim: Make sure that you are root, enable DMA and check your HW/OS set up.
write track data: error after 4274012160 bytes

Why I am reporting as a bug is I installed brasero and it has never failed with these images since.

Thanks.

Hi,

the error message of K3B is forwarded from the burn program wodim.
Brasero normally uses my libburn as backend.

wodim is not well suited for DVD or BD media.
cdrecord is a bit better, but still not compliant to MMC specs for
those media.
growisofs and libburn should work fine.
Afaik, K3B can be talked into using growisofs.

wodim and cdrecord send inappropriate commands to DVD+R before beginning
to write.
Nevertheless it is hard to imagine that wodim believed to reserve 4590 MB
while having reserved only 4076 MB and then running into a track overflow:
> Sense Code: 0x21 Qual 0x02 (invalid address for write) Fru 0x0

Have a nice day :)

Thanks Thomas.

I remember wrestling with k3b, wodim and cdrecord back when wodim was first on the scene.

Interesting though, looking at my settings it appears k3b is configured to use growisofs for dual-layer disks.

I have attached the k3b settings Tab.

Being a stubborn user of my own command line software (*), i do not know
k3b in practice.
In your screenshot it seems that "cdrecord" = /usr/bin/wodim claims
the capability to burn DVD. (Cough !)

Whatever, the error messages stem from wodim. No doubt.

(*) I will release a GUI frontend demo for xorriso soon.
    It is written in Tcl/Tk and so ugly that i hope for real GUI programmers
    to show mercy and begin developing eye-friendly competitors.

Have a nice day :)
