How do I reuse a DVD+RW disk using cdrecord?

Do I need to erase the disk first, or does a subsequent record simply go
over the top?

If I need to erase the disk, how do I do this?

Does cdrecord provide the facility to erase DVD+RW disks?

Mark.

If possible, I recommend you use a GUI application like K3B (KDE app) or
Brasero (Gnome app) to erase and write CDs or DVDs. Both give you a very
nice and easy to use GUI that hides those details.

This might be good advice if that's what you are looking for. I.e., if
you are looking for a "nice and easy to use GUI that hides those details".

Otherwise, be a man and "man cdrecord". Search for "erase". You'll
figure it out.

You can do a full erase of the disk if you wish, BUT the convention
is that you are recommended not to with DVD+RW, once the disk has
been initially formatted for use.

You just write over the top of what is already there.

From <http://www.isobuster.COM/tips.php?tips_page=9>

QUOTE

The big exception to all the above is DVD+RW (DVD plus RW).

The designers of the format were clever enough to decide that
there shouldn't be an erase function for this format at all.

After all a full erase only adds to the so called DOW (Disc Over-Write)
and thus reduces the quality of the media. If a full erase is truly
required by the user then the application software can still simply
write a neutral pattern over the complete surface of the disc with
the same effect.

And as a DVD+RW can have only one track in one session, changing the
inner circle structures is not needed either. If there is a track
already ... well then there is a track already .. why change that ?

If one wants to write new content then the old data can simply be
overwritten. Of course this also positively influences background
format and other features I won't go in to now.

In other words there is no erase command that an application can send.

If a user wants to quick erase a DVD+RW then the application software
must be clever enough to simply write some neutral data over file-system
structures (e.g. ISO9660 and UDF etc).

And in fact that's what most applications do when they quick erase a DVD+RW.

The man page doesn't actually say. The only reference to erase is as
follows:

Note that for unknown reason, the DVD-Plus alliance does not like that
there is a simulation mode nor a way to erase DVD+RW media. DVD+RW only
supports one write mode that is close to Packet writing; this mode is
selected in cdrecord via a the -dao/-sao option.

That doesn't really make much sense to me. Anyhow it turns out that to
reuse a disk, just insert it into the drive, and perform the record
operation as normal.

Cheers,

Mark.

Makes sense to me ... erasing first, then recording over
that erased space is redundant - "recording over" is simply
an erase-on-the-fly operation. Because new data are written
over, the TOC will be re-written and the older data will
be inaccessible (except with low-level tools).

Rumor has it that you could possibly "erase" before writing
new data using the "-force -format" switches:

[cdrecord man page quote]
-format
Format a CD-RW/DVD-RW/DVD+RW/BD-RE disc. Formatting is currently
only implemented for DVD+RW and BD-RE media. A 'maiden' DVD+RW
or BD-RE medium needs to be formatted before you may write to it.
However, as cdrecord autodetects the need for formatting in this
case and auto formats the medium before it starts writing, the
-format option is only needed if you like to forcibly reformat
a DVD+RW or BD-RE medium.
[/cdrecord man page quote]

While we're on this subject, I'd like to touch on something ...
it's something I feel is overlooked, yet very *important*.
It has to do with the "cdrecord fork" which happened a number
of years ago, but has lingered and is plaguing many users to
this day. I have been a most-recent victim.

In wanting to convert an avi file for use in a DVD format (i.e.
so that it can be played in a DVD player), I ended up creating
about 6 coffee coasters. And while doing research for some other
options (software for format conversion), I came across some
very valuable information at the "cdrtools" (cdrecord) website.

I'm not going to regurgitate the information in this post, but
will provide a link where you can read at your leisure:
http://cdrecord.berlios.de/private/linux-dist.html

Suffice it to say, I had this "broken fork" of cdrtools (better
known as "cdrkit" or "wodim") installed on my current openSUSE
11.2 64bit system (it's the default package for openSUSE).

I deleted the "cdrkit" package and its associated packages
(and marked them as "taboo - never install") and then installed
the "shily-cdrtools" packages.

Guess what? The rip (avi->dvd conversion) went flawlessly the
first and subsequent times and I've not had any other issues
with the "cdrtools" utilities - with the "cdrkit" (buggy fork)
utilities, I always had sporadic problems.

I'm appalled that SUSE, and other distro vendors, knowing full
well about this broken fork, and still includes the broken fork
as the "default" !!!

This is technology-dependent, I guess. For instance, flash memory
requires erase before rewrite because write can only change 1's into
0's, so you need to erase first to change all 0's into 1's.

You might want to try cdrskin and xorriso, or something else which uses
libburn and libisoburn (respectively). (I've not done so as yet, though.)

For DVDs, I normally use growisofs (dvd+rw-tools).

Broken or not, it is at least distributable.

(Old argument. Look it up yourself if you want more; it won't be hard to
find.)

Well then, when you've used it in various forms of writing/burning to
various incarnations of media (CD's/DVD[+-], and can report accurately
that it equals cdrtools, let us know ...

> For DVDs, I normally use growisofs (dvd+rw-tools).

What do you think growisofs depends on?

http://fy.chalmers.se/~appro/linux/DVD+RW/
Q. Do I still need cdrtools?
A. Yes. It should be explicitly noted that growisofs is a front-end
to mkisofs, i.e. invokes mkisofs to perform the actual ISO9660 file system
layout. Secondly, the DVD burners available on the market can burn even
CD-R[W] media and cdrecord is the tool for this job.

And you're saying cdrtools isn't?

GPL. And it works fine.

It does, but cdrtools includes both GPL and CDDL code, and the licenses
are incompatible. This might be ok if all authors grant permission, but
that should be made explicit and has not been. More troublesome is the
fact that Schilling has threatened Free Software developers with legal
action. All of this has caused many to conclude that is is best to
avoid cdrtools.

"Cdrtools are now available under a OSS license that gives *more* freedom
than the GPL ...

http://www.opensource.org/licenses/cddl1.php
search for "3. Distribution Obligations." and read on for more info.

The 'cdrtools' are being distributed by third parties as we speak,
such as openSUSE and other distro vendors. In my case, I merely
de-slected the 'cdrkit' tools and enabled 'cdrtools' (current version).

The issue I see is that the distro vendors are either "overlooking"
the fact they've set the 'cdrkit' package as default or they just
"don't care" and are leaving it up to the end user to discover the
broken nature of cdrkit.

Even I was initially "fooled" into thinking I was using the *real*
"cdrecord" ... until I ran "cdrecord --version" did I discover the
fact I was using the broken cdrkit toolset.

I'm no lawyer or license guru, but it does deserve to be mentioned that
Joerg Schilling's "cdrtools" is licensed under the CDDL,
while "wodim" - i.e. the "broken" variant - is licensed either under
the GPL or a compatible Free Software license - the BSD or Apache
license, perhaps.

"cdrtools" is freely downloadable from Schilling's repository, but I
don't know whether the CDDL supports distribution by third parties.
Like I said, I'm neither a lawyer nor a license guru. Wink

You could be waiting a long time for that. For a start, I neither have nor
intend to install cdrtools...

And since you want to know that, why don't *you* try it and see? Be sure only
to report if, as you put it, "it equals cdrtools", and remember that should
it not equal cdrtools in any way, you should not let us know that that is so.

>> For DVDs, I normally use growisofs (dvd+rw-tools).

dvd+rw-tools (which contains growisofs) depends on libc6, libgcc1, libstdc++6
and...
































genisoimage.

wodim, which is an ancient version of cdrtools, with a few alterations--
mainly so it can burn dvds-- is licenced under GPL. The modern cdrtools
( which has received constant development over the past 5 years since
the branch occurred) is licensed under CDDL. Both are open source
licenses, with some differences. There is less of a difference between
CDDL and GPL 2 than between GPL2 and GPL3. It is almost certainly any
GPL3 program which is undistributable in combination witht he GPL2
kernel (Torvald has stated that he will never distribute the kernel
under GPL3). The only issue with licenses is whether or not the license
holder will sue if the software is distributed and SChilling has stated
many many times in public, that he has no problem at all in cdrtools
being distributed. Part of the issue is personality. Schilling can be
rather abrasive at times, and some people do not like to be abraded. My
philosophy is that if the software is good, it is the duty of the
distributor like the distribution vendors to distribute. Many many
people have started writing cdwriting software, but none have kept at
it. Schiling has kept at it, writing good useful software, for well over
10 years. Alternatives where the writer looses interest after a year
are useless.

Yes, cddl does allow distribution by third parties.

No it does not. It works fine for some but does not work for others.
This thread started with statements by users of the failure of wodim.
Now just because it workd fine for you does not mean it works fine for
all. You know that.

Schilling has stated that he has permission from all the writers to do
so.

> fact that Schilling has threatened Free Software developers with legal

I beleive that was over the issue of the name. Other writers had changed
cdrtools and kept the name cdrecord. Those changes, in Schilling's
opinion had introduced bugs which had destroyed cdrtools, and were
ruining his reputation as a software writer.

To the detriment of the users of those distributions.

He needs to show that he has these permissions; including all relevant mail
in an appropriate place in the source would be a good way of doing this.

(I'm not aware of him having done so.)
