- Yet to be resolved: Debian is continually accessing the drives- even when no data is being transferred. With Jim's help we determined that SWAP was not involved. Does anyone have an idea of what could be causing this?
I would think that the drives should spin down if nothing is going on...

Does /etc/fstab list "noatime" in your mount options? If not, you'll want to change "defaults" to "defaults,noatime" against all your real filesystems.
