having problems with k3b, cdrecord

syd2669 · 07-03-2009, 01:21 AM

hi everyone, first time posting here.

I have been using linux for a while now........still a litle bit of newbie though.

I had my latop (toshiba M70-131) runing smoothly on mandriva 2008.0 since it was released for a year maybe. But recently i have been having this new problem K3b is showing "cdrecord has no permissions to open the device". I have already updated. I have reinstalled it recently 3 days ago, had reinstalled it previously too without any problems.

I checked the /etc/fstab file and this is what I got:

# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>

/dev/sda7 / ext3 noatime 1 1
/dev/sdb5 /mnt/win-e ntfs-3g defaults,locale=en_US.UTF-8 0 0
/dev/sdb6 /mnt/win-f ntfs-3g defaults,locale=en_US.UTF-8 0 0
/dev/sda1 /mnt/win_c ntfs-3g defaults,locale=en_US.UTF-8 0 0
/dev/sda5 /mnt/win_d vfat umask=000,iocharset=utf8 0 0
/dev/cdrom /media/cdrom auto umask=0022,users,iocharset=utf8,noauto,ro,exec 0 0
none /proc proc defaults 0 0
/dev/sda6 swap swap defaults 0 0

I tried changing: umask=0022 to umask=0.......didnt help
deleted users......no help
deleted ro......no help

Here is another one:

# sudo lshw -C disk

So I just changed everything back to how it was before i do something stupid and opted to ask for someone's help. Search on the net didnt help me much.

My drive is working under xp and i am also able to mount it and read files, install packages from cds etc........but it wont burn any cds or dvd. I cant burn audio/iso.....nothing at all. Any help guys. Plz.

I don't think you want to be using umask and iocharset in your mount options for the cdrom drive. Try it with something like:

Code:

/dev/cdrom      /media/cdrom       auto        noauto,users,exec,ro   0   0

Also, try reconfiguring K3B from: settings > configure K3B.
Also, make sure that your user is a member of the cdrom group. Open a terminal and run groups to see what groups you are a member of.
Also, try running K3B as root from a root terminal. If it works ok as root, then it is a permissions problem with cdrecord.

I tried what you said deleted umask etc........started k3b......its not burning the cd.

I tried configuring k3b......doesnt help......its not burning using TAO or DAO or SAO

Ran it as root same result. checked the user group too.

K3b is showing "unable to fixate the disk"
"cdrecord has no permissions to open the device"

I am really confused now.

What is the output of:

Code:

ls -l /usr/bin/cdrecord

This will report your cdrecord permissions.

syd2669 · 07-03-2009, 03:35 AM

Its as follows:

ls -l /usr/bin/cdrecord
lrwxrwxrwx 1 root root 26 2009-06-28 05:57 /usr/bin/cdrecord -> /etc/alternatives/cdrecord*

I restarted my laptop and tried to burn an mp3 on cd as root and its showing "buffer under run" and "use a lower speed to burn"........I checked the settings and the only speed I found is 4x and auto. The software buffer's box in the gui is not checked.......I havent changed anything there.

I don't know, but newer versions of k3b are a bit buggy, IMO, or they deal with permissions in a strange way.

I usually burn from the command line and it works. I recommend you try a different burning program or try using the command line. Maybe try:
http://bashburn.dose.se/

or I made a script for myself that burns directories and ISOs:
http://draconishinobi.50webs.com/slackware/scripts.html
(it is 'burnit' part of 'possibly useful scripts')
