[11.04] Unable or properly identify Blu Ray recordable disks (BD-R)

[Jerone Young]

Binary package hint: brasero

Using latest daily 10.10 daily build Sep 13 2010.

Brasero is not properly identifying Blu Ray Recordable disks (BD-R):

Nautilus is also seeing things in the same way when a BD-R is in the drive:

* Target inital fixes for 11.04 tree

Though to note it also may not be seeing capacity of the disk correctly it's supposed to be 25GB .. not 23.

[Jerone Young (jerone)]

Also could be an issue with udev as it says "disk type 00" this may be part of the issue?

[Robbie Williamson (robbiew)]

I don't believe Brasero supports Blu Ray. If OEM's want this support, they might want to think about partnering with Nero...or we could sell the app in Software Center -> http://www.nero.com/enu/linux4.html

[Pedro Villavicencio (pedro)]

That's correct, brasero doesn't support bluray yet, there's an upstream bug about that: https://bugzilla.gnome.org/show_bug.cgi?id=474325

udev detects that the drive is capable of writing BD-R and BD-RE (i. e. rewritable) media, and that your inserted medium is recordable, but not rewritable (BD-R). If this isn't correct, what should it be?

[Jerone Young (jerone)]

@Martin
       This is correct. According to Wikipeidia the media I'm putting in there is, a BD-R, is only writeable once. Don't have a BD-RE yet. But that is the read/write version.

        But it says the "disk type 00" .. which I'm not sure if that is supposed to be differnent for a BD-R. If not can mark invalid for udev.

[Martin Pitt (pitti)]

disk type 00 looks fine -- http://suif.stanford.edu/~csapuntz/specs/INF-8020.PDF defines three possible types, 00, 10, and 20, of which 00 is the common format ("CD-ROM with first track in mode 1"). Also, this information is only printed out for debugging, it's not used anywhere (or exported through udev).

[Jerone Young (jerone)]

The latest 10.10 build 9/17 actually fixes this issue for both nautilus & brasero

[Jerone Young (jerone)]

To add to my last comment. BD-R disks are not seen as "Blu-Ray R Disc" by both nautilus & brasero.

[Jerone Young (jerone)]

"not" meant "now" in last statment. So they are seen correctly.

I recently conducted a test using Ubuntu 10.10 (Maverick Meerkat), Brasero 2.31.92-0ubuntu1 and an external Blu-Ray Multi Burner. The media tested was Memorex 4x 25GB Single Layer Recordable BD-R.

Disk Type Recognition Test - PASS
==========================================
From what I can see in my test, using 10.10, the following issues have already been corrected:

-Inserting a BD-R disc causes nautilus to recognize it as "Blank Blu-Ray R Disc"
-Brasero recognizes the disc as "Blank Blu-Ray R Disc: 23.3 GB of free space"

==========================================
BD-R Burning Test - FAIL
==========================================
-Burning dialog has a setting for speed. It offers 8x although the maximum for the disk is 4x. Capabilities of disk are not probed.
-Burning dialog has a "Options" section is blank but still has a title. Expecting this is where you would have simulate options etc.
-Burning ends up with a failed attempt before starting the burn, resulting in one of the following two errors.
     - "Merging data is impossible with this disc"
     - "An internal error occurred"

Attached is a combination of brasero logs as debug information. These are the output of 'brasero -g' and of 'brasero --brasero-media-debug' while testing the recognition and burning.
