Ive got both a DVD and CD burner and neither seems to work. K3b writing program can see them but the burn button is greyed out.
I thought it was a permissions problem so I logged in as root and I still could not get either drive to burn. When I try to mount them I get no medium found.
Where should I start to get them working?
Thanks

Slack 1337, XFCE

Commandline burning may give some informative error messages. Have a look here for a start:

CD and DVD Writing from the Linux Command Line
http://www.andrews-corner.org/burning.html

Is the file you want to burn small enough to fit on the medium you want to burn to? For example, if you have a 715 MB ISO but, your CD-R can only hold 700 MB then the burn button will be greyed out. Hardware issue?

I tried the info on the link and at command line I get "media is not recognized as recordable"
message. I have tried two different brands of DVD-R, Sony and Memorex and both give me the same error message. I made sure the data was much smaller than the disk capacity.
Any Ideas?

So, when you try to mount a burned CD/DVD it says "medium not found" ?
And when you try to burn a CD/DVD you get "media is not recognized as recordable" ?

Can you post the output of 'lspci -k'.

Check what groups root and your users are in.

How old is the burner ? Make sure it support the media you bought.

EDIT: Try not running XFCE during the burn, don't startx and just try burning it from the command line.

All users are in the burning group.

Are both of these drives SATA along with the HDD ? If 'ahci' is built into the kernel I would change the controller mode to AHCI in the BIOS.

There is no burning group in Slackware, which groups are you a member of?


FYI The cdrom group is required as the cd/dvd devices are owned by root.cdrom

All the Hard Drives are IDE. How do I check to see if AHCI is built in the kernel?

I created the burning group so K3B could use it.
I am a member of:
Disk
Floppy
Audio
Video
CDrom
Plugdev
Power
Netdev
Burning.

When I try to open the User settings I get an error that says "Error Opening /etc/shadow for reading". could that have anything to do with the drives not working?

It is better to change group setting in k3b from burning name to cdrom, because there is a great chance that the devices files permissions are set by udev rules at boot (so they will reset unless you make custom udev rules which seems more complicated than change the k3b settings to me)

Anyway, what is the output with : dmesg | grep writer

This:

[ 4.493128] sr0: scsi3-mmc drive: 8x/32x writer cd/rw xa/form2 cdda tray
[ 4.498286] sr1: scsi3-mmc drive: 48x/48x writer cd/rw xa/form2 cdda tray

And the output with :

ls -l /dev/sr0
ls -l /dev/sr1

bash-4.1$ ls -l /dev/sr0
brw-rw-rw-+ 1 root cdrom 11, 0 Nov 6 09:30 /dev/sr0
bash-4.1$ ls -l /dev/sr1
brw-rw-rw-+ 1 root cdrom 11, 1 Nov 6 01:00 /dev/sr1

If I do chmod +rwx on sr1 and sr0 would that give full permissions and allow access to the drives?

Don't do that, you don't need to change permissions as you are in cdrom group already

Try run k3b from a xterm and see if there are error messages

I ran it from terminal and got no errors, K3b sees both drives but says theres no medium and after I add files the burn button is greyed out still. I have tried 2 different brands of DVD-R.
