Priblem with dvd mounting.PLEASE HELP

**ultimate_aektzis** · May 22nd, 2008

Hi everybody.I am a new Linux user and I have a liitle problem with my dvd drive.Before changing my desktop's OS I have burned some data to a dvd disk so that I can recover them after format.The problem is that when I insert the disk inside the drive and go to places computer and double-click on the drive's icon i take a message claiming that there is no disk in the drive.Have i done something wrong.I would be very grateful if you could help me solve the problem.
Sorry for bad english...

No need to apologize. Nobody knew English when he was born. He had to learn it.

Looks like the drive cannot read the DVD. Maybe the problem is with the DVD disk itself. Can you read it in another computer?

To discard other problems, check the following:

In a terminal type:

Code:

dmesg | egrep dvd

Mine says:

Code:

[17.223122] sr0: scsi3-mmc drive: 48x/48x writer dvd-ram cd/rw xa/form2 cdda tray

Note the sr0 after the square bracket. Yours could be different. Enter now

Code:

dmesg | egrep sr0

changing sr0 to whatever you have. Then enter:

Code:

cat /etc/fstab
mount

And post your results here

I will post my results but i cant understand how can i find "my" sr0???

**didac** · May 22nd, 2008

Sorry for not being clear. Once you do dmesg | egrep dvd the output line starts with a number between square brackets (seconds since booting when the event took place) Immediately after and before the colon, you have your device, sr0 or whatever it's in your case.

So we have:

periklis@p:~$ dmesg | egrep dvd
[ 22.684938] sr1: scsi3-mmc drive: 48x/48x writer dvd-ram cd/rw xa/form2 cdda tray

periklis@p:~$ dmesg | egrep sr1

I am looking forward for your help man

**didac** · May 22nd, 2008

I'm back online. Sorry about the interruption.

Do:

Code:

ls -l /dev/sr1
lrwxrwxrwx 1 root root 4 2008-05-22 16:01 /dev/sr1 -> scd1

Look at the bit after -> That tells you where your DVD is linked to. Now, you have two lines in your fstab for your dvd. One is /dev/scd0, the other being /dev/scd1. These two control your two cd-dvd's. I don't see anything wrong there, unless ls -l /dev/sr1 gives you a different result, like scd2, which I don't think.

If it gives you anything above scd1, add another line to your fstab by doing

Code:

sudo gedit /etc/fstab

and copy from the others too.

Be patient. We are arriving -- I think. Insert the dvd, count to 10. In Nautilus, enter in the address bar

Code:

/media

and you should see two folders pertaining to your 2 cd-dvd's. Open them, and you'll be there.

If so far into the game nothing has happened, cry. Your dvd is not recognised, maybe it has scratches and maybe another computer will open it. Sorry

**ultimate_aektzis** · May 22nd, 2008

I 've followed your instructions.so I typed

Code:

periklis@p:~$ ls -l /dev/sr1
lrwxrwxrwx 1 root root 4 2008-05-22 21:28 /dev/sr1 -> scd1

As I understood from your post there is no prob here.Right?
So I inserted a dvd drive waited for 10 sec and typed /media and I took the following

Code:

periklis@p:~$ /media
bash: /media: is a directory

Any cd icon appeared on my desktop

**didac** · May 26th, 2008

Sorry again for not being around. Have you solved the problem?

I wasn't clear enough. Type /media in the Nautilus address bar, in your 'Windows explorer', not in a terminal. You'll see a folder called cdrom1. It is inside there where your dvd files should appear. If there is nothing there, type in a terminal (now it's a terminal):

Code:

sudo mkdir /media/cdrom1

Eject and re-insert the cd. Wait for it to settle down and try typing /media or /media/cdrom1 in the Nautilus address bar again.

Sorry, but the problem looks more with the dvd. You'll have to try opening it in another computer or use recovery programs to get part of the data back.

**ultimate_aektzis** · June 5th, 2008

No.All folders in /media are empty.Probabaly my dvd drives are not supported by hardy heron.I wish ubuntu developers will do sth for that.

Thank you very much for your help didac.Respect...

**ultimate_aektzis** · June 23rd, 2008

I "recover" this topic as I want to ask whether is possible to connect directly with hardy developers explain them the problem and have some desired results like a possible solution or a kernel update.If it helps my drives appear in "my computer" area and my dvd drive(one of 2) is LG.I mention that as I think that LG does not make drivers for linux.
thanks in advance for your help
