  I asked our filed service rep about this a long time ago. The answer
  was no. The controller for the DN3xx series disks does not support
  multiple drives according to what I was told.

The guy was only partly right.  The controller on the dn3xx has two st506
ports, and you can put two disks on it.  Normally one would be a floppy and
one would be a winchester.  In theory you could plug in two winchesters, but
you would need to patch the os to deal with this.  I don't know anyone who
has tried this, but I know someone who is about to.
