| This page is based on the DVD+RW/+R
tools written by Andy Polyakov, and his WWW-page
is an important resource in trying to understand this page. Obviously, I
am working with OpenBSD, and to my unpleasant surprise it turned out that
the otherwise excellent cdrecord
tool doesn't support these kind of DVD recorders. Looking slightly
further, I discovered that Any Polyakov wrote some small routines that
accessed the DVD+RW drive on CD-ROM level for linux, allowing the
formatting of DVD+RW media, and the writing of ISO9660 file systems on
DVD+RW and DVD+R media. Because these tools were linux specific, I had to
port them to OpenBSD in order to use them. This is what I did.
Thanks to the help of Scott
Presnell, the tools have now also been ported
to NetBSD, and should work on that platform as well.
Andy has now taken these modified versions of his tools, and merged them
with his own toolset. You can therefore download the complete toolset from
his download
page (make sure to get version 5.5 or later). In case you've been
using the tools on the page you're currently
reading, I recommend
that you upgrade to Andy's tools.

For the instructions (and downloads), I
would like to refer to Andy's WWW-page,
which explains things in detail. The tools were tested using a Philips
DVD+RW-D01 but they should work will all DVD+RW drives.
Note that for OpenBSD (and probably other BSD) you will need to use the
/dev/rcd0c device, rather than the /dev/cd0c device, in order to
succesfully use these tools. Another
thing to be wary of is the fact that BSD reportedly can't mount
multi-session DVD write-once media.
You can write them using these tools, but
you won't be able to access them using BSD afterwards.

Check out our NEW FORUM for
discussion about the various DVD + RW issues. You can also post questions
which we obviously will try to answer for you.

|
| The tools all have a hard-coded LUN of 0. It seems no DVD+RW drives
have been manufactured with a different LUN, so this should pose no
problems.
|
|
|
| If you decide
to port the tools to a new operating system, talk with Andy. With his new
code setup it should be relatively easy.

|
|
| The tools (and their resulting media) have been tested with the
following drives/players. A * means that it has been tested by someone
else. All tests were done with dvd-rom-spec booktype DVD+RW media
containing at least one GB of data and DVD+R-spec DVD+R media containing
at least one GB of data.

- Andy Polyakov's
dvd+rw-tools. Without these source files, I would never have been able
to port these tools.
- Jörg
Schilling, whose open source policy for cdrecord allowed me to
learn more about SCSI access for OpenBSD.
- University of Rochester
for giving me the resources to do this project.
- Mosha for giving me WWW-space to
store these pages.
- David Giller, Eberhard Moenkeberg, David van Leeuwen, Erik Andersen,
and Jens Axboe, as I used their linux/cdrom.h file in the porting
process.
- Jorg Kennis, for his DVD+RW
WWW-site.
- Scott Presnell, for his NetBSD patch.
