can't copy cd using k3b

Quercus ruber · 10-10-2005, 02:39 AM

Hi

I can't copy cds with k3b. I can create a data cd project and burn it, and I can listen to an audio cd in the drive, but I can't duplicate cds. Can anyone suggest why not?

The relevant extract from my lilo.conf file looks like this:

Code:

# Linux bootable partition config begins
image = /boot/vmlinuz
  root = /dev/hda5
  label = Linux
  append = "hdc=ide-scsi"
  read-only
# Linux bootable partition config ends

my /etc/fstab looks like this:

Code:

/dev/cdrom       /mnt/cdrom       iso9660     noauto,user,unhide,ro  0   0
/dev/fd0         /mnt/floppy      auto        noauto,user     0   0
devpts           /dev/pts         devpts      gid=5,mode=620   0   0
proc             /proc            proc        defaults         0   0
/etc/fstab lines 1-9/9 (END)

and /etc/modules.conf:

Code:

# --- BEGIN: Generated by ALSACONF, do not edit. ---
# --- ALSACONF verion 1.0.5 ---

/etc/modules.conf lines 1-23/23 (END)

Any help would be appreciated

thanks

ps, I just tried it logged in as root and that works fine.

Run k3b setup. It will ask for the root password and it will change permissions for you.

Quercus ruber · 10-10-2005, 02:07 PM

I tried that and it an d it changed the permissions from 660 to 666, but I still can't copy a cd. When I press Start to start the copy, the copying cd dialog pops up telling me that the source disk is being checked. The cd drive rumbles away, but the minutes pass and nothing happens...

mlangdn · 10-10-2005, 04:24 PM

I just noticed that you only have one cd drive in fstab. You may have to copy the cd to a temp folder, then burn it. If the burner is the only drive, I'm thinking there is a setting to check before you begin that will copy the cd, then have you change before the burn begins. But definitely copying to a folder first, then burning the file will work.

Check the temp-directory, maybe user hasn't write-access to it?
Since it works logged in as root, it must be a problem with permissions somewhere.

Quercus ruber · 10-11-2005, 07:43 AM

Curiouser and curiouser. Or praps I didn't wait long enough...

Well, I checked the permissions for /tmp/kde-ros and I do indeed have write access. So just to see what happened, I put a data cd in and tried to copy that. No problem whatsoever. It copied all the data into the tmp directory, ejected the drive and prompted me to put a new one in, which it duly wrote. So I tried my audio cd again, went and made myself a cup of tea and when I came back, I saw the following list of error messages in the dialog box:

Code:

Checking source disk.
Copying audio CD.
No CD-TEXT found.
No Cddb entry found.
Could not open device /dev/sr0
Error while reading session 1.
Removing temporary files.
Removing images files.

So I had a look at /dev/sr0 :-

Code:

ros@darkstar:~$ ls -l /dev/sr0
brw-rw-rw-  1 root cdrom 11, 0 1999-04-13 06:24 /dev/sr0
ros@darkstar:~$

That's OK isn't it?

pingu · 10-12-2005, 01:34 AM

Hmmm... a bit strange this...
/etc/fstab says
/dev/cdrom /mnt/cdrom iso9660 noauto,user,unhide,ro 0 0
but audio CD wants to use /dev/sr0? Which is a device in itself, not a link to /dev/hdc.
A wild guess now: try adding /dev/sr0 to /etc/fstab the same way as /dev/hdc.

Quercus ruber · 10-14-2005, 03:57 AM

Hmmm

changing fstab seems a bit of a fudge, especially as it works when I'm logged in as root, which suggests a problem with permissions. Here is some more info. I hope it helps.

from dmesg:

Code:

Then I ran k3b from the command line, and here is an edited listing ...

Hi,
I am having the same problem with copying audio CD. OK with data yet no dice with audio. Did you finally manage to get it fixed?

Quercus ruber · 11-13-2005, 07:23 AM

no I still haven't got it fixed.....

I tried executing cdparanoia from the command line to see if that worked and it didn't. I got this message:

Code:

dev/cdrom exists but isn't accessible.  By default,
cdparanoia stops searching for an accessible drive here.
Consider using -sv to force a more complete autosense
of the machine.

More information about /dev/cdrom:
Checking /dev/cdrom for cdrom...
        Testing /dev/cdrom for cooked ioctl() interface
                /dev/scd0 is not a cooked ioctl CDROM.
        Testing /dev/cdrom for SCSI interface
                No generic SCSI device found to match CDROM device /dev/scd0

After a lot of googling, I made 1 small change:

Code:

# chmod 666 /dev/sg0

and then it was fine. See this post:

http://www.linuxquestions.org/questi...d.php?t=302699 .

I hope this helps someone
