Comment 16 for bug 62896

Don't known if I should be presenting this here.

Burning a CD:
Being new to Linux and Unix and having installed Ubuntu 7.04 (Feisty Fawn ) a month ago, I don't known if any of this information is useful. Prior to this installation, both devices worked with Windows (don't want to use) and Fedora 6 (problems).
 When I try to burn a CD with C/D / DVD creator, the following messages appeared:
(1) Reload a rewritable or blank disk (it can read size of file) and (2) writing files to disk.
When I right click on CD-RW/DVD RW Drive:
 This message appears: Cannot mount volume. Invalid mount option when attempting to mount the volume 'UDF Volume'.
Also, when I try to mount the floppy, this message appears; cannot mount volume. mount: /dev/fdo is not a valid block device.

Both of these devices can read a disk.
Below are commands I ran after looking a bug reports #62986,#66254,#44233 and #6415.

Quickly guessing the name of a drive capable to write CD-R, please wait...
