Re: [CentOS] formating DVR-RW

[Thomas Schmitt]

Hi,

> No message, it just went to 100% CPU and quit responding.

Did you start it in a terminal window by a shell command ?
In this case my local K3B (2.0.2) floods it with debug messages.

> DVD-R

So i need to get a DVD-RW into blank unformatted state.
K3B offers me "Format and Erase" but not blanking.
So:
  xorriso -outdev /dev/sr4 -blank all
to make it similar to a blank DVD-R.

900 seconds later:
New Data Project -> fiddle in some directory -> Burn
"Writing Mode" offers me "Auto", "DAO", "Restricted Overwrite".
But i want "Incremental". Grrr. So i try to enforce it with tab "Misc"
and set "Multisession Mode" to "Start Multisession". (DAO cannot keep
the medium appendable. So growisofs should choose "Incremental".)
I let "Writing Mode" at "auto".
Button "Burn". CPU (Xeon 4x2) varies between 1100 and 3500 MHz.

After 598 of 632 MiB have been reported as written, there is no progress
message for a while although the drive seems to burn normally.
This could be growisofs' habit to fill DVD-R[W] up to 1 GiB at least.
But the CPU is quite idle. (100 % never happens. But 12.5 % would be
one busy core.)

Then suddenly writing is done and verifying begins. Finally K3B says
"Written data verified".
The resulting DVD-RW is indeed appendable. So this run was Incremental
and not DAO.

I import the written session and add another directory tree.
In "Burn" -> "Misc" i chose "Finish Multisession" as "Multisession Mode".
After burning, the medium has two sessions and is closed.

I could try "Writing mode" "Restriced Overwrite". But that is the formatted
medium state which is not available for DVD-R media without "W" in their
type name.

Could you try
* whether Writing Mode "auto" and Multisession Mode ""Start Multisession"
  yield success in a first session,
* whether the DVD-R is then readable on all intended drives,
* whether the DVD-R then takes a second session with "Finish Multisession"
* and whether the DVD-R is then readable and shows the files from both
  sessions.


Have a nice day :)

Sounds like a growisofs problem.

If it was with unformatted DVD-R or DVD-RW media, does it resemble this

Have you ever used k3b? It works very nicely.


I have now.
It can format or whatever it needs to do to write my dvd-rws.

How do I get it to finalize?

Re: [CentOS] formating DVR-RW

[Thomas Schmitt]

Hi,

i am upstream developer of libburn. Nevertheless, the following is intended
to be purely technical info, not advertising.

Better do not use wodim with DVD media. It was forked from a CD-only
version of cdrecord and got added not-so-skilled code for operating DVD.
One should use dvd+rw-tools or a program that has libburn as backend.
I am not aware whether cdrecord is meanwhile willing to format DVD-RW.


With dvd+rw-tools and according to an old cheat sheet of mine, a DVD-RW
gets formatted like this:

  dvd+rw-format -force /dev/sr0

(Iirc, the option -force was needed if there is already an ISO filesystem
 on the medium.)

libburn's frontend cdrskin has a command line interface that is roughly
compatible to wodim or cdrecord. (There are also Xfburn, xorriso, and
Brasero's libburn plugin.)
A formatting run looks like this:

  cdrskin -v dev=/dev/sr0 blank=format_overwrite


Fred Smith wrote:
> Why would one format a cd/dvd?

DVD-RW can have two states: unformatted sequential and formatted to
"restricted" overwritable.

The latter can take 32 KiB chunks of write data at 32 KiB-aligned addresses.
It does not have to be blanked before re-use. growisofs and libisoburn
can do multi-session on it, like they do with DVD+RW, DVD-RAM, BD-RE.

Unformatted DVD-RW behave much like DVD-R (which is good for testing).
Blanking them for re-use is only swift if you do not want to do multi-session
on the blank medium. For multi-session they must be blanked fully, which
lasts as long as a full write run.

My own experince since 2004 is that formatted DVD-RW can be re-used more
often before they die. Unformatted DVD-RW seem to be less long living.
The older the drive, the earlier they fail.


Giles Coochey wrote:

Formatted DVD-RW can be used as random access read-write device by help
of buffering device /dev/pktcdvd* created by pktsetup(1).
But this is an invitation for trouble, as is with the other overwritable
optical media types. Random access is slow and the frequent overwriting
of particular media blocks reduces life time.

(The other overwritable DVD and BD types need no /dev/pktcdvd* because
 they can be used for addressing with 2 KiB granularity.)

Thank you for flying xorriso. :))
It has a cdrecord-wodim-compatibility mode described in man 1 xorrecord.
Formatting is done by:

  xorrecord -v dev=/dev/sr0 blank=format_overwrite

The native command mode is more versatile but demands learning new names
and new rules. See man 1 xorriso.

  xorriso -outdev /dev/sr0 -format as_needed

The mode "as_needed" formats what can be formatted and is not formatted yet.
It throws no error if the medium is not suitable for formatting.


Have a nice day :)

I suggest that you try xorriso.  In recent years I've had much better
results with xorriso for writing DVD's and Blue Rays then any of the
older programs.

I write to RW media all the time without formatting it.
I might "blank" it, but that isn't the same thing.
After posting I realized that one might want to use a UDF filesystem
on RW media, and I suppose for that purpose one would need to format
it, though I've not done that on a CD or DVD, only on USB.

If you have a rewriteable one.  I am assuming (and we all know what that
means :) ) that the OP has such a disk.  

Otherwise, I can't think of another use case where one would format an
unused drive, but there may be one.

According to the man page for wodim - formatting is not supported for DVD-RW.
You might take a look at growisofs and dvd+rw-format.  The latter command, in
spite of the name, can deal with DVD-RW media.

It is possible that the optical drive in your computer does not support DVD-RW
media.  The only way I know of to find what media are supported is to use K3B.
