But how does a newbie know about PATA and master-slave ? :))

The specs are in MMC-5, but not easy to put together
to a usable procedure. DVD+R gets at least a sketch at
4.3.6.2.2 "The Host's Perspective".

I wrote my own cheat sheet
  http://libburnia-project.org/browser/libburn/trunk/doc/cookbook.txt
where DVD-R handling is described under
  "Sequential DVD-R[W] Cookbook"
and DVD+R under
  "DVD+R[/DL] Cookbook"

The main difference is that for DVD-R the drive gets sent
a Mode Page 5, like for CD-R. DVD+R need less preparation
before writing can begin. But no Mode Page 5 also means
no dummy write mode is possible with DVD+R.

Not described by SCSI are the physical differences which
seem to become decisive when drives begin to show first
symptoms of failure.
That's why i proposed to try a different media type.
If that works it would be a limited remedy and it would
make clear that the drive is beginning to lose its
capability to burn DVD-R.
The long term remedy would then be to get a new drive.


Have a nice day :)

Thomas
