The first ~170kb of /dev/sda got blown away with what seems to be a logging output
by Powertop, when I was playing with the tuneables.
(Luckily the first partition starts later :-))

Why is that I don't know, but maybe when turning on the SATA knobs
something goes wrong. I'm afraid to try again, but I accept rather higher
power use than data loss again :-/

Sorry for the confusion...
