ubuntu 12.04 cannot mount DVD after burn .iso file with Brasero

Asked by siamkom on 2012-07-03

Hi,
  I use Ubunut 12.04 server 64 bit. I have burn the .iso file (size 4.4 GB). here is my step.
  1. open the brasero (version 3.4.1)
  2. insert the blank DVD -R.
  3. in the brasero, I select the "Burn Image" project.
  3.1 select the image to write. (It is the CentOS 6.2 64 bit, file size 4.4GB)
  3.2 select the disc to write. (DVD -R drive that I insert the blank DVD)
  3.3 in the property button, I clicked and change the /tmp folder to /myhome/temp folder
  3.4 I click burn.
  4. After burning is finished, the program cannot eject the disc automatically. I must eject by manual.
  When I eject by manual and insert the DVD again. My Ubuntu desktop cannot automatic mount the DVD. I cannot access the folder /media/cdrom and mount in this folder also.
  I surely that the DVD which I burned it has data because insert into another PC it can see the data, folders.
  Could you please help me? If you need more information please let me know.
Regards,
Siamkom

Hi there,

you probably can't boot from dvd, because you don't have enabled in bios to boot from cd driver in bootup. If you have this enabled, then you probably didn't burn your dvd at the slowest speed. Try burn your dvd in the lowest speed which offers your dvd burner.

If that helps you solve your question, please mark thread as solved.

Regards,
Miha

Hi Miha,
  Thanks for you information. I try to using the lowest speed but it still won't work.
  I try to using the command line with
  growisofs -speed=1 -dvd-compat -Z /dev/dvdrw=dvd_image.iso. It won't work also.
  After finished the command line, my dvd drive auto reject then I re-entry it. But my unbuntu still cannot read the burned DVD disc.
Best regards,
Siamkom

Hi,
  FYI,
 After used the command line growisofs -speed=1 -dvd-compat -Z /dev/dvdrw=dvd_image.iso.
 Then I used
   sudo mkdir /media/kk
   sudo mount -t iso9660 /dev/sr0 /media/kk
  I waited around 3 minutes, but no any response from my terminal.

FYI, here is my result of my testing in burning the DVD-R 10 dics.
Notebook Information:
File name / size : Test.iso /3.6 GB.
DVD RW: internal DVDRW from Acer Aspire 4752G
OS: Ubuntu 12.04 desktop 64 bit.

Solution of failure to write .iso to the DVD disc.
GUI Mode: Braser/K3b/Nero Linux --> fail, it can write data into the DVD disc but it cannot read in another PC (including my notebook cannot read also). I know it has data in the DVD disc because OS didn't show the the blank DVD when it detecting
Command Line: wodim/cdrecord --> fail, same as the using GUI mode. below is the command that i use.
   $ wodim -v -dao speed=4 dev=/dev/sg1 Test.iso or
   $ wodim -v -dao speed=2 dev=/dev/dvdrw Test.iso or
   $ growisofs -dvd-compat -Z /dev/dvdrw -speed=1 Test.iso

Solution of success to write .iso to the DVD disc.
I installed the VMWare workstation + Win7(x86) + ImgBurn --> Yes, it can burn file Test.iso
 - In My Computer (Win7), it show my drive dvd to 'DVD RW'
 - I think, using the VMWare Player is also the same as VMWare workstation.
*** I guess, my ubuntu may be detect my DVD Drive into another mode. (I just guess)

One more thing, when I use command below (reference from https://help.ubuntu.com/community/CdDvd/Burning)
 $ wodim --devices
    wodim: Overview of accessible drives (1 found) :
    -------------------------------------------------------------------------
     0 dev='/dev/sg1' rwrw-- : 'HL-DT-ST' 'DVDRAM GT32N'
    -------------------------------------------------------------------------
 $ ls -l /dev/cdrom
lrwxrwxrwx 1 root root 3 Jul 25 07:52 /dev/cdrom -> sr0
 $ ls -l /dev/cdrw
lrwxrwxrwx 1 root root 3 Jul 25 07:52 /dev/cdrw -> sr0
 $ ls -l /dev/dvd
lrwxrwxrwx 1 root root 3 Jul 25 07:52 /dev/dvd -> sr0
 $ ls -l /dev/dvdrw
lrwxrwxrwx 1 root root 3 Jul 25 07:52 /dev/dvdrw -> sr0

  The link /dev/ is point to sr0 but I don't know why 'wondim --device' is point to /dev/sg1
  I guess (again) if I can change the point from /dev/sg1 to /dev/dvdrw, it may be write .iso into my DVD disc into my Ubuntu.

hope it use full for anyone.

Siamkom.
