Hi, I have been doing my best with this but I am stumped...I would be well grateful for any help at all.

I'm running Ubuntu Gutsy, attempting to get cdrom0 to open up to wine (its an exe file I am after)....the message arrives - "Invalid mount option when attempting to mount the volume"

Ok...I entered blkid and get:

xxxxxxx@xxxxxxxxx:~$ blkid
/dev/sda1: UUID="cd1e001f-684e-4a3d-9ff3-41e88a13ed37" SEC_TYPE="ext2" TYPE="ext3"
/dev/sda5: TYPE="swap" UUID="c6846a7c-35db-4c0f-af06-80a886dda4f0"
/dev/sdb1: SEC_TYPE="msdos" UUID="4CB8-1D52" TYPE="vfat"

Armed with that information I attempted to add the info from my misbehaving disk to the end of my fstab as:


# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
# /dev/sda1
UUID=cd1e001f-684e-4a3d-9ff3-41e88a13ed37 / ext3
/dev/sda1 / ext3 defaults,user_xattr,errors=remount-ro 0
defaults,errors=remount-ro 0 1
# /dev/sda5
UUID=c6846a7c-35db-4c0f-af06-80a886dda4f0 none swap sw 0 0
/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec 0 0
/dev/fd0 /media/floppy0 auto rw,user,noauto,exec 0 0
#/dev/sdb1
UUID=4CB8-1D52/media/sdb1 vfat defaults 0 2

So then I tried again with...again on the end of fstab:

# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
# /dev/sda1
UUID=cd1e001f-684e-4a3d-9ff3-41e88a13ed37 / ext3
/dev/sda1 / ext3 defaults,user_xattr,errors=remount-ro 0
defaults,errors=remount-ro 0 1
# /dev/sda5
UUID=c6846a7c-35db-4c0f-af06-80a886dda4f0 none swap sw 0 0
/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec 0 0
/dev/fd0 /media/floppy0 auto rw,user,noauto,exec 0 0
/dev/sdb1 /media/cdrom0 vfat rw,user,noauto,exec 0 0

And so 'dsmeg | tail' gave

xxxxxxxxx@xxxxxxxx:~$ dmesg | tail
[ 69.399532] eth0: no IPv6 routers present
[ 564.566003] UDF-fs: No partition found (1)

tried changing 'vfat' to 'vfat16' zilch. A bit depressing.

Where am I going wrong?

Big thanks to anyone who can help me out of this hole!

Looks like you have two different devices that you are trying to mount to the same mount point. Furthermore, is looks like you are trying to mount /dev/scd0 with two different filesystems at the same time (udf and iso9660).

Hallo Bigrig, thank you for your time. yes, I was scrabbling around in the dark trying odd options as the normal options were getting me no-where. This morning I had a brain wave and tried the CD in question on a windows box. Showed the CD was faulty. Whoooops. So easy to get sucked into the details. I am getting over my blushes now...duh!
