Hi Bart, I did indeed consider that; see below. With btrace I checked that it is hddtemp that is accessing the hd and causing it to spin up. FWIW, smartctl has the same behavior (as you already mentioned in <a href="https://bugs.launchpad.net/ubuntu/+source/acpi- support/+bug/59695/comments/253">comment 253</a>).
