That happened to me the other day too. I'd mounted a USB flash drive, unplugged the USB hub, replugged it, remounted the drive, and then of course I couldn't umount the first mount. I did a umount -f and the machine crashed instantly. Is this the sort of thing that's really hard to handle, or might it be safer one day? I don't know how serious it is to do bad things to mounted file systems, but I'm curious. Bill -- William Denton : Toronto, Canada : www.miskatonic.org : www.frbr.org
