Progress: Just to see what'd happen, I simply ran this:

# /usr/libexec/udisks-daemon &

Next, launched Dolphin: The two partitions on the hard drive are
listed :-)

But when I click on either of them:
"An error occured while accessing '48.8GiB Hard Drive' : the system
responded: An unspecified error has occured : Not Authorized:
GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name
