There is a very handy utility that comes with most Linux distributions called lsof(8) that will allow you to list all open files on a filesystem and find out what process has them open. If you can figure out what is accessing the filesystem when the OS refuses to unmount it, you can get in the habit or quitting or killing that application before attempting a umount.
