Automounting is fine if you are going to use it all the time, but if you only use it once every few months (like me) then automounting will just annoy you as it puts a PC0??? icon on your Workbench every time you put a floppy in the drive.
(Note to self: take PC0: out of Devs/DOSDrivers and put it back in Storage/DOSDrivers) :-D
