apt-get upgrade spins up idle drives

apt-get upgrade seems to spin up idle drives unnecessarily.

In a two drive machine where sda is system and sdb is an idle data drive:

apt-get update will update the necessary files and leaves sbd spun down.

apt-get upgrade upgrades files on sda but also spins up sdb even though no updated files reside on sdb.

I would only expect sbd to spin up if data needed to to updated on sdb

Can you please give an example package where this happens? A case that I remember would be updates of grub or the kernel where update-grub re-scans all drives, but that's intentional.

Before running apt-get update and upgrade sdb was idle.

Output of hdparm -C /dev/sbd shown before and after apt-get update and upgrade in text file.

Thanks, that should be enough to have someone look at it.
