Verb. Sap. Make that:
# mount -t cd9660 -o ro /dev/acd0c /cdrom
For best results, set up all of the options etc. in /etc/fstab, and
then just use:
# mount /cdrom

You've either got a process with it's current working directory
somewhere under /cdrom, or you've got a process with an open file
descriptor (or a memory map) on one of the files on the CD.
Try using:
# fstat -f /cdrom
to see if you can identify the culprits. Then either close them down,
or CD to elsewhere in the filesystem if it's an interactive session.
Once the CD Rom is idle, you should be able to dismount it easily.
Cheers,
Matthew
