I used to mount my sticks & umounted via AMD, that saved me some
pain when pulling sticks without thinking.  For some reason I stopped
doing it that way, (can't remember why some problem), but meaning
to try again.  Would be a good idea if we gave syntax examples in
manuals, at least that would save some of the people some of the
pain some of the time (whilst not actually being The solution) :-)
