David,

The WD Green drives were notorious for aggressive powerdown a few
years ago.  The 100,000 head park warranty could be eaten up in Linux
in a matter of weeks as I recall.

Checkout the package storage-fixup which was used to force the always-on mode.

https://build.opensuse.org/package/show?project=openSUSE%3A13.2&package=storage-fixup

I'm not sure if it helps after suspend or not.  Or if it still works
in a systemd world.

Also, it doesn't look like it has had an update in a few years, so
even if it does still work with the infrastructure you may have to add
your drive model number, etc. to the config file that is used to
identify problem drives.

If it doesn't still work, it might be worth a bugzilla.  As I recall
storage-fixup came from the LKML ATA devel team.
