External dvd+rw device ...help needed!


I have an old pc(1999) with two usb ports and I bought an external DVD-rw [LG 2166 USB] with a usb port! I would like to use it on my slackbox in order to store some large chunk of data on dvd's....and not for watching dvd's.
All I have done so far is to plug it in and try to see if my slack 10.2 installation -kernel 2.4 recognizes it. Obviously not till this moment.
I do not mind if the speed of burning dvd's is undermined cause my pc-usb ports are the old type while my dvd-rw port is usb2.
Further down I ve posted some relevant system messages I get and my fstab....I know those messages may point to some direction but I am not quite sure where that is....:

-do i need to mount the external dvd+rw device....and if yes...how?

-do i need a driver for the device.....? or simply a dvd burning-utility-software?

I use xfce and I haven't seen a dvd burning utility available...and when I alternatively use KDE (cause I still haven't managed to alt-shift to another keyboard locale with xfce)I don't see a dvd burning utility there.

-do I download k3b...and all the patch prerequisites listed on the www.k3b.org ?

-is there a default dvd+rw utility on slackware 10.2 that I haven't noticed ?

is it a module-problem ?

hope I 've posted the proper info to get a fairly straitforward answer from someone out there.....thnx in advance people!

I ve also been through several HOWTOS...but don't seem to get any specific help there...maybe I haven't yet stumbled on the right one!

cheers to all

Your device seems to have been detected properly and is attached to /dev/sr0. I don't know the particulars of DVD burning, but presumably you don't need to mount it first (well you certainly don't need to mount CDs before burning). If you want to read from DVDs in the drive, then obviously you'll need to mount it. Something like the following should work:

# mount /dev/sr0 /mnt/dvdrw.

This assumes the dvdrw directory exists under /mnt, but obviously it's up to you where you mount stuff. I'm not sure about filesystem type for DVDs, though. You might want to check the mount man page to see if there's any useful info there.

You don't need to get the source for K3b and compile it yourself, because there's a Slackware package for it. The package is in extra (a sub-directory of the slackware-10.2 directory) on any Slackware mirror, but is also on which ever CD provides the /extra directory (it's either CD 3 or CD 4, but I'm not sure). I think you'll probably need the cdrtools package installed and Slack does come with the dvd+rw-tools package as well. Both of those can be found in the ap directory on the mirrors (or on CD 1 or 2, again I can't remember which).

FWIW, I'm not sure those kmod messages are harmful. I get those as well and they don't appear to be affecting anything for me.

Hope this helps a bit.

from the looks of everthing just make sure /dev/cdrom points to /dev/sr0 which you can do by

ls -l /dev/cdrom

if it doesn't than

ln -sf /dev/sr0 /dev/cdrom

k3b is fine for cd burning

thnx for the replies Nylex and Boow,
however I need to mention, as uncertainty crowls in real fast here....
that the dev/cdrom device listed in the fstab on my post is not the external dvr+rw but the
legacy cd/dvdrom of the machine.

I have the impression that in order for the external dvd+rw to be of any use ...it must be on my fstab file....or not?

You don't really need to change the /dev/cdrom symlink to point to your DVD+RW drive. Also, no, you can use the device without it being listed in fstab. I use my CD-RW drive without an entry in fstab. You can of course make an entry for the device in there if you like.
