A STK library with four drives requires five connections to the server, one
for each drive and one for the robot. A Quantum library, on the other hand,
only would require four connections because the robot connects through one
of the drives. That's why loaderinfo shows "No" for all the drives in an STK
library and "Yes" for one drive in a Quantum -- that's the drive through
which the robot connects.
