Can't burn ISO images.

[olavsu1]

Binary package hint: k3b

Hi
I can't burn ISO images in ubuntu 10.04 64bit.

I get error message "cdrecord has no permissions to open the device"

only dirs & file names can write, but no data.

k3b log show this:

This problem is not specific for k3b/kde (lucid), this also happens under gnome / brasero.
No problem burning iso's under Windows7.

[D. Hugh Redelmeier (hugh-mimosa)]

This but persists: it is in 12.04 LTS with all current updates applied.

There are several problems. The first one is that K3b incorrectly reports the problem. wodim fails with an I/O error, well into burning:

Track 01: 10 of 625 MB written (fifo 100%) [buf 91%] 10.2x.
Errno: 5 (Input/output error), write_g1 scsi sendcmd: no error

Very clearly this isn't a permission problem.

In my case, I was able to figure out that the problem was that on-the-fly collection of files from an external disk was not fast enough to keep the burner running at full speed. A buffer underrun is very bad for burning.

I avoided the problem in either of two ways: lowering the burn speed, or preparing an ISO image before burning (just one tick box in K3b's burn screen, but it requires a lot of tempfile space).

Summary: K3b must understand wodim's diagnostics better and must report them correctly and accurately to the user. The current K3b diagnostic is highly misleading.
