I don't know what is writing kedglobals, but you can disable korgacrc
by removing korganizer from the taskbar and disabling alarms.
Ah ha! Thank you---that stopped -both- files from being written.
Apparently korganizer's alarms were what was doing it.
OTOH, is are your partitions mounted noatime? that was the single
largest win to keep disk from spinning up for me. The other one was
enabling laptop_mode using the script provided by the patch.
Wasn't mounted noatime; remounting it that way didn't help until I
nuked korg's alarms. Haven't tried laptop_mode.sh yet & may not need
to; with this change (and remember that I'm running cpudyn and have
/proc/sys/vm/laptop_mdoe set to 1), my disk spun down and -stayed-
down until syslog wrote a "-- MARK --" entry; I've now added "-m 0"
to its init so that won't happen. I may remount without noatime just
to see if random thing are reading behind my back (presumably they'd
be operating out of the cache in RAM most of the time, but I'm
curious, and I actually sometimes use atime to see if I've used a
