    Unable to reburn DVD+RW


    Hi,
    I have recently installed Ubuntu 8.04 on my laptop and have a problem with reformatting DVDs. I can burn new DVDs and even access the data. However when I try to reformat the DVD, it does not allow me to do it. Upon searching the net, I came upon a command to force format the DVD from the command line.

    dvd+rw-format -force /dev/dvd


    This started off like it was gonna do the trick. It stopped after half a minute and then Ubuntu does not recognise the DVD. I dont think It is mounted after the attempted force formatting it does not show up in the places menu.
    I am a total noob. So any help would be appreciated.
    Thanks in advance

    Which DVD burning program do you use? K3b is considered by far the best program for this job. (Hope it gets ported to Windows soon. One more great common app to make transition to Linux easier!!)

    To install it type in terminal:
    Code:
    sudo apt-get install k3b
    Or open System->Administration->Synaptic and search for k3b.

    I have used Brassero and GnomeBaker. Not used k3b yet,but will try it out and let you know. I just assumed that force formatting it from the terminal shoudl work...but it didn't for some reason.

    Hi,
    Just installed k3b and tried to reformat the dvd. It said " Reformat not necessary. DVD already empty". So I copied an avi file on to it which it successfully did. However post burning, it is unable to mount the dvd to view the contents. Not sure why it cannot mount although it recognises that there is a DVD in the drive.

    I have just tried to mount the dvd from the terminal and I get the following message

    samsom@sony-vaio:~$ mount /dev/scd0
    mount: wrong fs type, bad option, bad superblock on /dev/scd0,
    missing codepage or helper program, or other error
    In some cases useful info is found in syslog - try
    dmesg | tail or so


    So I tried dmesg |tail ( as per the computers instructions )which gave the following out put.


    samsom@sony-vaio:~$ dmesg |tail

    Another unrelated query....
    How do I display the terminal output in a nice square window like everyone does?
    Thanks

    try with another dvd RW disk.
    Maybe your DVD RW disk died.

    I have tried with others. A brand new DVD is fine. I can copy avi files and watch them on the telly. Its when I try to reformat them that the problem starts

    it says "no such file or directory". There is a space between i and /dev/...., right?

    the "dvd rw device" is a device node in your /dev directory
    it can be
    /dev/hdX #if you have IDE device X=a,b,c,d,e,....
    /dev/sdX #in case of SATA device

    some distro provides
    /dev/cdrom
    /dev/dvd

    so try something similar

    hdparm -i /dev/cdrom
    or
    hdparm -i /dev/dvd
    or
    hdparm -i /dev/hda #IDE1 master
    or
    hdparm -i /dev/sda #first SATA device
