You may lose data doing this but at least for NFS volumes if something
is stuck I umount the file systems with the "-l -f" options. I'm not
sure if it'll work for NTFS but if you really want to force unmount
try

umount (path to mounted file system) -l -f

You may want to check to see if any files are in use on that file system
first, for that I'd use lsof

lsof | grep (path to mounted file system)
