My Toshiba drive has a small jumper on the bottom for the density select
method. It comes jumpered for density select based on the hole/lack of hole, 
but I briefly experimented with changing the setting. Took all of 5 minutes
(and most of that was just removal/replacement of the floppy drive itself.) No
soldering in tight little spaces required!

This is precisely why I chose to return the jumper to its normal setting - 
what good is a floppy disk if only _I_ can make use of it? That's what I have
a hard disk for! I want floppies so that I can transport files to other
machines. Of course, this is only my own preference - I'm sure you have your
reasons for not wanting to take floppies you write on your system over to
your office or a friend's house... :-)
