It is now fixed!  In summary....
I found there was an electronic fault with the drive, but once that was fixed,
it still did not work.  The steps needed to get it to work were
(1) Removing the terminating resistor pack from the 360K drive.  This is
apparently a requirement if it is the last floppy drive (B:) in the system.
The TRP was located at the back of the disk drive board, and was about the
only removable component on the board.
(2) Covering pin 34 on the disk's controller connector with tape.  Someone
suggested cutting the corresponding wire on the controller cable, but the tape
solution is a bit easier to reverse.  I'm not exactly sure why this works...

Thanks to everyone who offered assistance.
Cheers, Liam.
