cant mount drive

[Thornton]

i just tried using KDiskFree to mount the cd rom drive..and it gave this
error..this is differnt as it isnt what i was getting before of being in
use by something else so it couldnt be mounted.

Called: mount -tudf,iso9660,noauto,owner,kudzu,ro -0 0 /dev/cdrom
/mnt/cdrom

mount: fs type ro not supported by kernel

Could something else be wrong that is causing the cd to not load at all?

Thanks
