To find out what is going on (next time) use

If you have an HD that isn't an issue, then you can just dump the output to
a logfile:
dbus-monitor --system > /home/user/logs/dbus-monitor-system.log
{etc., fix as needed}
Then mount/unmount until your system behaves badly again...

Just thought that I ought to tell what I discovered. As usual, the solution is
something much more unimaginative and basic.
Indeed it was merely a problem of lack of power. I was trying to attach 4
different portable USB hard drives to my laptop via an unpowered 4-port USB
hub, and my machine couldn't keep up with the demand as I added more video
files to the last two of the hard drives.
What puzzled me was, they worked just fine for the first four months or so.
Both my Belkin USB hub and the mini hard drives (all are WD easystore)
themselves have very short cords, and when I set up my laptop, I no longer
had anywhere to put the hard drives, and the cords were too short, which
would have left them dangling in space.
So, the culprit: I used an old USB extension cord to attach the 4-port USB hub
to the laptop. The USB extension cord is rather old, and I didn't really give
it a thought; but it's probably 1.0, whereas the laptop has 3.0 ports, the
hub is 3.0, and the hard drives themselves are probably 3.0, too, I believe.
I hope that I can find some newer USB extension cords. I wonder, do they even
make them any more?
