cdrecord problems, mandriva 2006 kernel 2.6.x

[psymole]

Hello, The problem is the following:

I´ve recently updated to mandriva 2006 free form mandrake 10.0 community. Since the update i´ve haven´t been able to burn cd´s (any type) unless i become root (full switch no su) and choose a very low writing speed (2x). Before the update i could burn with speed of up to 8x with no buffer under run (same hardware).

I´ve used the k3bsetup tool for the permission to no avail. I´ve also used chmod to change the permission of the cdrecord bin.

Any help would be greatly appreciated.

My specs:

Mandriva 2006 free.

Kernel: 2.6.12-12

Open a terminal, log in as root and launch

msec 2

Then try burning again.

[psymole]

I tried running the command as root and then burning with k3b and keep getting the same error .

Thx anyway

[Kojak]

Is your user added to the cdwriter group? If not, try that one. It should solve the problem.

[psymole]

Sorry i took so long but my isp was terrible the last couple of days.


There are only two groups on my pc. root and one that has the same name as te user. There is no cdwriter and im to much of a newibie to know how to create a cdwriter grup with the apropiate permissions. If you could point me in the rigth direcctions it would be great.


Thanks.

[Kojak]

Open the MCC (aka "Configure your computer) → System → Users → Modify user → and adjust the permissions there. There MUST be a cdwriter group.

[psymole]

Change the permissions and still nothing. Same error.

Thanks a lot

[antidrugue]

Change the permissions and still nothing.

What is the output of

groups

then?

Did you use K3Bsetup to adjust "cdrecord" and "cdrdao" permissions?

[psymole]

[topo@dc85d2918 ~]$ groups
topo cdrom cdwriter

Thats the output.

And yes i did use k3bsetup but still nothing. When i used k3bsetup and i restarted k3b i got a message saying that cdrecord didnt accept the changes since an older kernel.

Thanks a lot

[antidrugue]

Ok, what are the permissions and ownership on those : /usr/bin/cdrdao, /usr/bin/cdrecord, /usr/bin/cdrecord.mmap, /usr/bin/cdrecord.shm ?

ls -l /usr/bin/cdrdao
ls -l /usr/bin/cdrecord*

?
