I would assume that SG is not to blame but rather
the SATA specific code. Possibly even specific to
the VIA VT6240 SATA controller.
Burning seems to work with a VIA VT6421 and with a
nVidia CK804 controller (i asked a friend about
his well working hardware with contemporary SuSE
Linux).
Do you plan to go on with exploring the problem ?
I absolutely do. I realized that in a couple of my later replies to Jörg yesterday I inadvertently cut the list from the recipient lists, I'll probably send out an update on what he was able to learn from my further testing with Windows for the sake of anyone coming by later and looking at the list archives.
In short, though, burning with cdrecord works (I think as expected) in Windows, which I think everyone can already guess from the exchanges on the list.
Either way, it doesn't work in linux so doing backups to DVDs (which is generally how I like doing my backups) becomes a pain, to say the least, if I have to backup my ext3 partition data from Windows. So I'm pretty motivated to see this one through. And buying an add-on SATA controller is my last resort since that benefits no one but me. :-)
Else we could repeat the old experiment which i made
with a user on the debburn-devel list.
It resulted in this error
5 1A 00 PARAMETER LIST LENGTH ERROR
when any mode page was sent.
That was the list of steps you sent yesterday? I was focused on Jörg's suggestions since my preference is to continue using what I know (that would be cdrecord) but I'm all for gathering as much data as I can before I try to approach SCSI and/or SATA developers.
If you post a bug report then please point me
to the place where the discussion happens.
Will do. My preference at this point would be to do it somewhere like the Ubuntu bug tracker, but that will complicate things slightly since Ubuntu ships wodim and most of my testing has been post-wodim-removal. But we'll see how that goes. I had remarkable success there before when I brought up alsa problems.
