usually this means you have a file in the CD-ROM directory (/mnt/CDROM ) which you have opened. make sure if you are using a computer with X that you close all windows or if you are using the command line, you dont have any files opened in the bacground (using the & command)

so to find out which files are preventing you from unmounting your filesystem (CDROM) send the lsof ( lsof - list open files)

you are most like are going to get a big list so to narrow down you list, use the grep utility to show only the files in the CDROM, you can use this command for example

lsof | grep mnt

hope that helps
