Unusual CD data disc ?
 

Today I inserted a Nokia's E51 new software CD disc into my T23 machine.
The disc was auto-mounted as usual but no files were shown via mc in the terminal nor in the konqueror.

In Windows they are normally existing and working.

Isn't it weird ?

dmesg gave me only this while loading the disc:
ISO 9660 Extensions: Microsoft Joliet Level 1
ISO 9660 Extensions: RRIP_1991A

Any conclusions folks ?

If I'm not mistaken, you have to ensure that support for these file systems are enabled within your running kernel. I remember specifically that the Microsoft Joliet CDROM extensions need to be enabled, but I believe that it should be selected by default. I'm not certain about RRIP_1991A though, as I don't recall this option within the kernel configuration.
