I was copying some files to a newly set up USB HD, and then did some umounts when done. Well they are still running, and

I have never seen 'kill' fail.
What can I do other than reboot?
Well, a kill will fail to kill if the process is a zombie or in an uninterruptable state. If top doesn't show any zombies then the process is probably uninterruptable and I think this shows up as a D state in top.
