Maybe it's just the hddtemp daemon with the temperature polls keeping 
your data drive(s) awake? To find out more exactly I suggest you monitor 
r/w access in syslog:

#this will put a comment about read/write access into your syslog:
echo 1 > /proc/sys/vm/block_dump

#live monitoring syslog:
tail -f /var/log/syslog

#switch off syslog r/w comments:
echo 1 > /proc/sys/vm/block_dump

Hopefully this will give you the necessary hints

Cheers!
