Managing optical drive

[SigurdF]

Hi,
I just changed to Kubuntu 10.10 completely after I tried Ubuntu + KDE alongside of Windows. To do so I burned important data on a DVD. But now I am desperately searching in Dolphin to find the Optical Drive with all the data I want to move to the Hard Drive again. How can I see and handle a data-dvd in the optical drive?
Kind regards,
Sigurd

Re: Managing optical drive

I believe you'll need to install certain files onto your computer to view DVD's.
Go into a Konsole/Terminal, and put this in to get most major supports:

sudo apt-get install kubuntu-restricted-extras

Once your done with that, we'll put Medibuntu onto the computer as well: It'll give you additional restricted support, and it will hopefully help, this link will provide useful instructions:

https://help.ubuntu.com/community/Medibuntu

If neither of those help you out, its past my lesser skills, but I hope they do work!

Hi,
I think there is a misunderstanding. My DVD does not contain a DVD-Video. It is simple a Data-DVD with my stored data before installation of Kubuntu. I only want to see the files on the DVD and copy them to the Hard Drive.

Re: Managing optical drive

Yes, I realized this. But I've noticed that without the restricted-extras, and people tell me about Medibuntu, that it causes..compatability issues? I'm not sure. I'm assuming you burned this CD from Windows? And did you keep Windows, or is it 100% Kubuntu now? because if Windows is still there, you can still access your Windows partition through Dolphin file manager, and youll be able to get the files that way as well.

all you should half to do is put the DVD in the drive and when the device notifier pops up click open with dolphin...........or if the disk has been in for a wile just open dolphin and you should see it in the places panel on the left side..(F9 togels it on and off if you dont see it ) and click it.

if this is not the case let us know ....you may have some problems

the kubuntu-restricted-extras package just installs java,flash,mp3 support,DVD playback(but not libdvdcss2 needed for playing commercial DVD's) ,and lame
and their are NO compatibility issues with using Medibuntu ..........provided you use it correctly

Re: Managing optical drive

If you have/had a 'modern' version of Windows, then the file type is going to be ntfs, and you will need to ensure that you have ntfs-ng (believe that is correct) installed in order to be able to read/access those files.

ntfs-3g

BUT on the DVD even riten in windows shouldent the data be in iso9660 ?

If it's a 'data' DVD, I don't believe so. iso9660 is the format when an iso file is burned to CD/DVD.

Re: Managing optical drive

I dont know about that......look hear

http://en.wikipedia.org/wiki/ISO_9660

and I just checked a data DVD in K3b and yes it is in iso9660 .....but it was burned hear in Kubuntu

Re: Managing optical drive

Hi,
Some months ago I had installed Ubuntu alongside of Windows. Later I added the KDE surface. Last week I decided to change completely to Kubuntu. So I stored my files on a USB stick and some DVDs. I burned the DVDs with Ubuntu. Now I only have Kubuntu on my computer. When I insert a Data DVD nothing happens, no notification or anything else. And nothing appears on the Dolphin panel. It is simple not there for Kubuntu. But K3b burner under Kubuntu recognizes the DVD drive.
So what can I do?

Searching information

> HOWTO find Kubuntu's manual / reference / guide / documentation / help


How it should work

> KDE UserBase > Plasma > DeviceNotifier


Coasters

If the burn was not succesful then CD/DVD can't mounted.

The K3b will show information from a DVD coaster.

[img width=400 height=184]http://img820.imageshack.us/img820/9915/coastera.png[/img]

but the mount operation is not possible.

An example

Looking the DVD device:

ls -l /dev/dvd*

lrwxrwxrwx 1 root root 3 2011-04-11 13:23 /dev/dvd1 -> sr0
lrwxrwxrwx 1 root root 3 2011-04-11 13:23 /dev/dvdrw1 -> sr0

The DVD device is the dvd1 (or sr0).

Making a mount point (konsole):

sudo mkdir -p /media/test

With an unbroken DVD the manual mount

Mount, konsole, readonly:

sudo mount -o ro /dev/dvd1 /media/test

The data DVD is mounted to the /media/test and the the data can be read from the /media/test.

The dmesg command output is:

dmesg

[ 3455.764049] ISO 9660 Extensions: Microsoft Joliet Level 3
[ 3455.771477] ISO 9660 Extensions: RRIP_1991A

The DVD can be unmounted with the command:

sudo umount /dev/dvd1

With a coaster

Inserting the DVD coaster and trying to mount it:

sudo mount -o ro /dev/dvd1 /media/test

The output is:

mount: you must specify the filesystem type

The system can't read the filesystem type, with real DVD it is not a problem.

Giving the flesystem:

sudo mount -t iso9660 -o ro /dev/dvd1 /media/test

and the output is:

mount: wrong fs type, bad option, bad superblock on /dev/sr0,
missing codepage or helper program, or other error
(could this be the IDE device where you in fact use
ide-scsi so that sr0 or sda or so is needed?)
In some cases useful info is found in syslog - try
dmesg | tail or so

and the dmesg is telling:

[ 3141.982284] Info fld=0x10
[ 3141.982286] sr 3:0:0:0: [sr0] Add. Sense: Logical block address out of range
[ 3141.982294] sr 3:0:0:0: [sr0] CDB: Read(10): 28 00 00 00 00 10 00 00 01 00
[ 3141.982304] end_request: I/O error, dev sr0, sector 64
[ 3141.982332] isofs_fill_super: bread failed, dev=sr0, iso_blknum=16, block=16

Sometimes it is possible to recover the data but here it was not possible > Topic: How to copy an unfinalized DVD?.

Re: Managing optical drive

Hi,
This all sounds very complicated.
Meanwhile I found out the following: Disk Utility does show the Optical Drive. And when I insert my Data DVD it recognizes it and I can mount it under media - fine. Now I start Dolphin. And Dolphin now knows the folders of my Data DVD under media. But when I want to see the files or when I try to copy a folder nothing happens. I mean there is only the order missing that the Optical Drive will read again.
Under the aspect that Ubuntu and it's variations are meant to be for people with little or no money (Africa for instance) I cannot understand that the optical drive is not usable for storage functions. A blank CD or DVD is way cheaper than an USB stick. Of course USB sticks are the future. But for saving money the optical drive should be available. Please do not misunderstand this. It is meant as a kind advice.
Kind regards,
Sigurd

Re: Managing optical drive

Hi,
My last hope was to use a computer with Windows. Today I had this chance. But even Windows does not manage to copy the files from the Data-DVD to another place. I can see all the data. But i cannot copy them. These data were burned on DVD by Ubuntu burning software. So what is wrong? And what can I do to copy these data on my hard drive?
I really appreciate your advice.
Regards, Sigurd

Re: Managing optical drive

I understand that you are totally focused on the particular files on a particular DVD, so probably no one is going to be able to give you a satisfactory answer about that.

Here are some thoughts that I had after reading this thread:

- whenever you make a backup on a new (to you) kind of media, it is very useful to verify it immediately, at least the first time
- you have referred to burning "with Ubuntu" or "with Kubuntu", but there are actually a number of burning packages. brasero, K3b, mp3cd, etc. Although I think they all use the same "engine", they just offer different user interfaces. I have had good results with K3b for years, and it does have a "verify" function to confirm correct burning.
- the media quality are important, generally, and even with a good quality brand, individual disks can be defective
- optical drives are not flawless

So, have you tried to use the command line to copy files from the DVD? Just curious -- if it outputs an error message, then you might learn more about the nature of the problem. If you insert the DVD in your running Linux system, it should be automatically mounted on /media. So, at the command line (i.e. in a terminal window) you should be able to issue

cd /media

and then

ls

and see the name of the DVD (if you gave it a label) or else it might have a designation like "disc1" or something like that. So, once you find what name it has, you can

cd /disc1

and then

ls

and it should list the files. So, at that point, you can use the Linux "cp" command to try to copy a file. If there is a file named xyz.txt, then you could copy it to your user's home directory with a command (issued at the /media/disc1 prompt) such as:

cp xyz.txt /home/sigurd

and either it will copy it, or it will give an error message that says (hopefully) why it cannot copy the file.

Re: Managing optical drive

Hi,
Thank you very much for your advice. Probably you are right and the DVD does not work. I used K3b for the burning process. But I did not verify the burned data. I guess now I can forget the data on that DVD.
