While I always try to format 400K floppies as 800K, I have not tried
formatting either as 1.4M.  However, the June issue of MacWorld has
a blurb about this in their "tips" section.  They say that although
you can punch a hole in the 800K disk, the coatings differ between actual
1.4M disks and 800K disks, and thus, the 800K disks are much more prone
to losing data over time if formatted as 1.4M.

Mea culpa.
