How can I mount an UDF picture CD/DVD?

Hello friends!

I am trying to see an UDF volume picture CD. When insterting that CD I get an error message telling me Slackware can't mount the CD (dev/sr0).

If I try to open it from the command line, I also get an error message. The command I use is:

# mount -t udf /dev/sr0 /mnt/dvdfolder

The error message I get is

Code:

mount: block device /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

What should I add in fstab in order to mount this type of CD/DVD?

It has been created with win and in win the cd can be read. Maybe it was created win win Vista. I've read somewhere that UDF disc created with Vista are not readable in Linux because Vista doesn't follow UDF standards. But...I can't believe this easily.

I will appreciate your help.

Thank you very much.

You may need to recompile your kernel to support UDF.
IIRC, it isn't enabled by default, but I'm not sure about the stock kernels. I do remember having to explicitly enable it when I rebuilt my kernels.

If you are using a stock kernel, you can check /boot/config for
CONFIG_UDF_FS=y
CONFIG_UDF_NLS=y

in the CD-ROM/DVD Filesystems section, or .config in the kernel source directory if you've made a custom kernel.

Awhile back I ran across a kernel patch that was for making win-vista-created udf's visible under Linux. I'm not sure whether the patch has made into the kernel yet, though. You don't say which OS/kernel version you are using so it is hard to say whether your kernel should be supporting that or not.

Why do you find it so hard to believe that vista or any other MS product fails to conform to a given standard? The bug you mention is well known...
