Hi

I have a Slackware 13 installation on an Acer laptop. I'v never had a problem
reading CD-ROMs before but one I got with a printer doesn't seem to work.
It mounts fine as an iso9660 but there are apparently no files on the disk even
though df says 300M is used.

In dmesg it says:

[ 2350.439313] ISO 9660 Extensions: Microsoft Joliet Level 3
[ 2350.508223] ISO 9660 Extensions: RRIP_1991A

I'm wondering if the RRIP extension is causing the issue?

Thanks for any help

Try mounting with the unhide and/or the norock option.

The norock option worked. Thanks for that.

Any idea why the extensions wouldn't work properly? Is it more likely to be
the CD or my system thats at fault?

It's the way the CD was mastered. The man page for mkisofs lists several
options for hiding files and/or directories depending on whether it's
Rock Ridge, Joliet, of UDF.
