Only history. I think the /dev/fd1.1440 (/dev/fd1 ) or for your case
the /dev/fd0.1440 ( /dev/fd0 ) stems from System V. They try to differentiate
between the devices. It may be useful to use these long names, if you
want to write to a floppy in another format than the default one.
So, if you want to write a 720K floppy in a 1.44Mb drive. Then the name
will choose the right format. The /dev/fd0.720 should produce on write
a 720Kb floppy and the /dev/fd0.1440 should write a 1.44Mb floppy for
a 3.5" drive.
For reads it shouldn't matter, the driver should detect it :-). You see
the word should :-), i have not tested it yet.
