Anyone an idea about where to start investigating this issue? Where

If you are using gnome it just loves to seek out disks and
access them any time any kind of a file dialog opens. This
once worked, but may not any longer:

Also systemd seems to have an affinity for touching
disks as well. I have a USB disk for backups that is
normally not mounted, is listed in /etc/fstab with "noauto",
yet recently I've noticed every time I reboot, I have
to wait for some systemd message about syncing headers on
disk [sdf] (which takes a while because the disk is
very slow and has to spin up first). Not sure when it
started happening, but it certainly didn't always
happen because it is irritating enough to notice.
