Excuse me for my English, Martin. I'll tell you what I've done. I use Ubuntu Lucid. I've updated udev, libudev0 and libgudev-1.0-0 packages from your ppa. Then I've inserted DVD+RW with an information recorded on it. Then I typed in terminal the command 'sudo /lib/udev/cdrom_id --debug /dev/sr0' and there is what I've got. d@d-l:~$ sudo /lib/udev/cdrom_id --debug /dev/sr0 main: probing: '/dev/sr0' cd_inquiry: INQUIRY: [HL-DT-ST][DVDRAM GSA-T20N ][WP03] cd_profiles: GET CONFIGURATION: size of features buffer 0x0160 cd_profiles: GET CONFIGURATION: feature 'profiles', with 14 entries feature_profiles: profile 0x12 dvd_ram feature_profiles: profile 0x11 feature_profiles: profile 0x15 feature_profiles: profile 0x16 feature_profiles: profile 0x14 dvd_rw feature_profiles: profile 0x13 dvd_rw feature_profiles: profile 0x1a dvd_plus_rw feature_profiles: profile 0x1b dvd_plus_r feature_profiles: profile 0x2b dvd_plus_r_dl feature_profiles: profile 0x10 dvd_rom feature_profiles: profile 0x09 cd_r feature_profiles: profile 0x0a cd_rw feature_profiles: profile 0x08 cd_rom feature_profiles: profile 0x02 cd_profiles: GET CONFIGURATION: feature 0x0001 , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x0002 , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x0003 , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x0004 , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x0010 , with 0x08 bytes cd_profiles: GET CONFIGURATION: feature 0x001d , with 0x00 bytes cd_profiles: GET CONFIGURATION: feature 0x001e , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x001f , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x0020 , with 0x0c bytes cd_profiles: GET CONFIGURATION: feature 0x0021 , with 0x08 bytes cd_profiles: GET CONFIGURATION: feature 0x0023 , with 0x00 bytes cd_profiles: GET CONFIGURATION: feature 0x0024 , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x0026 , with 0x00 bytes cd_profiles: GET CONFIGURATION: feature 0x002a , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x002b , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x002c , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x002d , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x002e , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x002f , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x0033 , with 0x08 bytes cd_profiles: GET CONFIGURATION: feature 0x0037 , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x003b , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x0100 , with 0x00 bytes cd_profiles: GET CONFIGURATION: feature 0x0101 , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x0103 , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x0104 , with 0x00 bytes cd_profiles: GET CONFIGURATION: feature 0x0105 , with 0x00 bytes cd_profiles: GET CONFIGURATION: feature 0x0106 , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x0107 , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x0108 , with 0x0c bytes cd_profiles: GET CONFIGURATION: feature 0x010a , with 0x0c bytes cd_profiles: GET CONFIGURATION: feature 0x010b , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x010c , with 0x10 bytes cd_profiles: current profile 0x1a cd_profiles: profile 0x1a media_dvd_plus_rw cd_media_toc: READ TOC: len: 20, start track: 1, end track: 1 cd_media_toc: track=1 info=0x4(data) start_block=0 cd_media_toc: last track 1 starts at block 0 cd_media_info: disk type 00 cd_media_info: hardware reported media status: complete cd_media_info: data in blocks 0 or 16, assuming complete Then I've started Brasero and have chosen Fast Erase. (I don't know how it is written in English, I use Russian localization.) Brasero blanked my disk, opened the tray and showed a message that process have been finished and it was all right. Then I've inserted blanked DVD+RW. Message: "You've inserted blank disk, choose the application, bla-bla-bla" At that moment terminal once again. d@d-l:~$ sudo /lib/udev/cdrom_id --debug /dev/sr0 main: probing: '/dev/sr0' cd_inquiry: INQUIRY: [HL-DT-ST][DVDRAM GSA-T20N ][WP03] cd_profiles: GET CONFIGURATION: size of features buffer 0x0160 cd_profiles: GET CONFIGURATION: feature 'profiles', with 14 entries feature_profiles: profile 0x12 dvd_ram feature_profiles: profile 0x11 feature_profiles: profile 0x15 feature_profiles: profile 0x16 feature_profiles: profile 0x14 dvd_rw feature_profiles: profile 0x13 dvd_rw feature_profiles: profile 0x1a dvd_plus_rw feature_profiles: profile 0x1b dvd_plus_r feature_profiles: profile 0x2b dvd_plus_r_dl feature_profiles: profile 0x10 dvd_rom feature_profiles: profile 0x09 cd_r feature_profiles: profile 0x0a cd_rw feature_profiles: profile 0x08 cd_rom feature_profiles: profile 0x02 cd_profiles: GET CONFIGURATION: feature 0x0001 , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x0002 , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x0003 , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x0004 , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x0010 , with 0x08 bytes cd_profiles: GET CONFIGURATION: feature 0x001d , with 0x00 bytes cd_profiles: GET CONFIGURATION: feature 0x001e , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x001f , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x0020 , with 0x0c bytes cd_profiles: GET CONFIGURATION: feature 0x0021 , with 0x08 bytes cd_profiles: GET CONFIGURATION: feature 0x0023 , with 0x00 bytes cd_profiles: GET CONFIGURATION: feature 0x0024 , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x0026 , with 0x00 bytes cd_profiles: GET CONFIGURATION: feature 0x002a , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x002b , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x002c , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x002d , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x002e , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x002f , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x0033 , with 0x08 bytes cd_profiles: GET CONFIGURATION: feature 0x0037 , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x003b , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x0100 , with 0x00 bytes cd_profiles: GET CONFIGURATION: feature 0x0101 , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x0103 , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x0104 , with 0x00 bytes cd_profiles: GET CONFIGURATION: feature 0x0105 , with 0x00 bytes cd_profiles: GET CONFIGURATION: feature 0x0106 , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x0107 , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x0108 , with 0x0c bytes cd_profiles: GET CONFIGURATION: feature 0x010a , with 0x0c bytes cd_profiles: GET CONFIGURATION: feature 0x010b , with 0x04 bytes cd_profiles: GET CONFIGURATION: feature 0x010c , with 0x10 bytes cd_profiles: current profile 0x1a cd_profiles: profile 0x1a media_dvd_plus_rw cd_media_toc: READ TOC: len: 20, start track: 1, end track: 1 cd_media_toc: track=1 info=0x4(data) start_block=0 cd_media_toc: last track 1 starts at block 0 cd_media_info: disk type 00 cd_media_info: hardware reported media status: complete cd_media_info: no data in blocks 0 or 16, assuming blank Well, I can say: great job, Martin! Your fix seems to work like a charm - at least for me, as I have tested. Now I can use Brasero again, can blank my disks and burn, blank and burn :) Thank you! -- Yours, Dmitriy Kodanev > For people who are affected by this and are using 10.04: Can you please > add my "sru-test" PPA at > > https://launchpad.net/~pitti/+archive/sru-test > > and upgrade to the udev there?
