If the directory permission bit indicates it isn't writable the bad permission
mode error should get returned. (The CD was burned with read only permission on
the directory.) It isn't until an actual entry is attempted until the error
should return sorry can't write. The question is why is the system checking if
it can write until after it has checked the directory permission bit? Of course
standards are wrong all the time.
