I have Slack 12.2 installed. I used the same command that I
use for CD`s with correct number for dvd burner(1001,1,0).
Cdrecord recognises the dvd burner and it says:
Total size 3753 MB = 1921708 sectors
Current Secsize: 2048
cdrecord: Data will not fit on any disc.
cdrecord: Cannot write more than remaining DVD/BD capacity.
It`s a new dvd+r disk. There`s nothing on it. Do I need
something else in the command?

Though not probable, this link may help:

Thanks guanx but I don`t see anything there to help me.
I`ve used cdrecord to burn cd`s with no problems.

Instead of cdrecord try growisofs:

* writing first track (current directory)

growisofs -Z /dev/sr7 -R -J .

* writing next track (current directory)

growisofs -M /dev/sr7 -R -J .

* writing ISO image

growisofs -Z /dev/sr7=image.iso

* erasing disc

growisofs -Z /dev/sr7=/dev/zero

* formatting disc (restricted overwrite mode)

dvd+rw-format -force /dev/sr7

* blanking disc (sequential mode)

dvd+rw-format -blank /dev/sr7

* media info

dvd+rw-mediainfo /dev/sr7

Ditto, I just use growisofs it works every time for CLI burns

I already have the iso. Cdrecord seems to be seeing the directory
only(secsize=2048) and not the DVD disk. Today I used the DVD burner
to blank a cdrw and burn geexbox. It worked OK. I have two windows
programs running on wine and they can`t see the DVD burner. I ran
winecfg and set the path(E.

The command growisofs referred to by w1k0 above is used to burn an iso that you have to a dvd.

Hello AlanL,

A new version of cdtools is available. From 12.2 changelog:

I suggest that you upgrade this package and see if your problem still persists.

As mentioned above, use the 'growisofs' command to burn the iso file.

I upgraded cdrtools but that didn`t change anything.
Thank you for the growisofs info w1k0. I made a nice
coaster! I forgot the = and got the iso on the dvd.
Got it right the second time and it worked perfect.
I still wonder why cdrecord can`t see the dvd disk?
Thanks to all.....Alan.

cdrecord need to be run with root privileges ie either as root or setup a sudo entry or as some do, change perm on it so a user can run it.

Whereas, growisofs must be run as a user.

Next, I cat a script I use to burn DVD

Run it like so:

al@P5Q:~$ dvdb ./my_dvd_iso_2_burn.iso

root@P5Q:~# cat /home/al/bin/dvdb
#!/bin/sh
# file to dvd command
# growisofs -dvd-compat -Z /dev/dvd -r -J /path/to/files
# this script burn a .iso to dvd
# growisofs -dvd-compat -Z /dev/dvd=$1;
growisofs -dvd-compat -Z /dev/sr0=$1;

Really ? I usually run both as root just to make sure I won't end up with a coaster.

The nice feature of growisofs is that you don't need to blank rewritable disks before you burn new set of data on them. You just have to use growisofs -Z /dev/sr0 -R -J . or growisofs -Z /dev/sr0=image.iso command. So practically you can stay with three first commands mentioned above. You can also use growisofs -M /dev/sr0=/dev/zero command to finalize multisession disks but be careful and don't use by mistake -Z switch instead of -M one.

For years I've had a sudo entry for cd burning.

(a few) year(s) [so many months, actually -- perhaps approx 20 months ago give or take a bit] ago was the first time I ever ran growisofs. I ran it as root and it informed me cannot be run as root, need to run it as a user. It has always worked fine for me run as a user. I've never looked back, nor have I ever tried again to run growisofs as root.

cd burning (not using growisofs) I still make use of my sudo entry.
