No messages to /var/log/messages as a result of those commands; I ran several times and did a sync too, just in case. I very much doubt that something is regularly accessing the drives because I have a script that runs every 1/2 hour to check and log status. The drives stay "standby" for hours (even days) at a time unless I specifically access something on the RAID array. Then, they stay "active/idle" until I manually set them to "standby".

hdparm standby timeout not working for WD raptors?
I can't get "hdparm -S" to work at all.
Using "hdparm -S 1" should set the timeout to
5 seconds, but the drives stay active/idle all the
time. When I set to standby manually, the drives
stay on standby for days, and start up fine when
they are used. I know this because I logged status
every 30 minutes using crontab.
They just don't standby automatically.
I'm using 5 identical drives (see below for drive
info), with software RAID.
Any suggestions? System details follow.
