[root at obsidian root]# umount /mnt/cdrom
umount: /mnt/cdrom: not mounted
[root at obsidian root]# umount /mnt/cdrom
umount: /mnt/cdrom: not mounted
[root at obsidian root]# umount /mnt/cdrom
umount: /mnt/cdrom: not mounted
[root at obsidian root]# umount -f /mnt/cdrom
umount2: Invalid argument
umount: /mnt/cdrom: not mounted
[root at obsidian root]# umount -f /mnt/cdrom
umount2: Invalid argument
umount: /mnt/cdrom: not mounted
[root at obsidian root]# umount -f /mnt/cdrom
umount2: Invalid argument
umount: /mnt/cdrom: not mounted
[root at obsidian root]#

But when I tried to then burn using k3b I get this error again:

Error trying to open /dev/hdc exclusively ... retrying in 1 second.
Error trying to open /dev/hdc exclusively ... retrying in 1 second.

I'm not sure how its not mounted yet its in use.

Thanks
