Try: fuser -muv /cdrom

Finally, a couple of things that are not detected by fuser/lsof:

 1. Do you use NFS? If yes, try doing:

        /etc/init.d/nfs-kernel-server stop

    before unmounting. kNFSd sometimes grabs handles to exported fs.

 2. Do you use quotas? If yes, try turning quotas off with:

        /etc/init.d/quota stop

    before unmounting.
