I must be paranoid :-)  Not only do I do that..  if I have an internal
drive (terminated) and expect to add external drives, I unterminate the
controller and plug a terminator into the back of the machine.  :-)

Agree!  Agree!  More lights never hurt nobody.

As for the connectors war waging elsewhere...

I know "Centronics" is ugly but it's universally understood in my experience
(maybe _because_ it's ugly!)...  and you need a way to distinguish between
four different major types of 50-pin connectors... DB-50, Centronics, HD-50,
and IDC dual-row connectors...

As an additional note, Sun's "new" external desktop storage packs now use 
the HD-68 connectors, even for non-wide devices.
