Sorry for a late reply...

The RunPowersaveCommand= tells upower to run hooks
in /usr/lib/pm-utils/power.d/ via calling /usr/sbin/pm-powersave whenever
power state is altered (e.g. plugging the AC power). Changing it to 'false'
will disable calling pm-powersave command altogether. However, on my system I
have nothing in that directory which calls hdparm (and yes, I disabled the
above option). Do you happen to have a 'harddrve' hook there?

Regarding KDE: just kill X, from tty call something like "upower -d" (as a
normal user) to start upower if it's not running already, and replug the
external power...
