I have tried what some contributors have said. Just to answer some questions and issues raised. I am trying to get my system to recognise (mount) my twin DVD drives. My research had led me to believe that a cure would be to place entries in /etc/fstab but that has not worked. I am using 14.04 LTS and I installed it from a DVD ISO image I had lying around along with other distros. I installed it alongside my windows vista and yes I can boot into either through GRUB. Deleting the 2 entries I made in /etc/fstab plus the ref to the floppy disk drive, then rebooting had no effect. Placing a pre burnt DVD drive had no effect and syslog showed nothing as far as I could see. (My vision is really too bad at the moment) At this stage do you think I should be changing /proc/mount instead. I have a vague recollection that when booting /etc/fstab is not even consulted. Maybe I should just give up for now until my vision improves hopefully.
