Ok, here's something most linux geeks take for granted, but
for those newbies going from windows to linux...they might ask
how to i format a floppy disk?
in windows you simply right click on the a drive and click quick format
in linux, there's a two step process...
    $> fdformat /dev/fd0
    $> mkfs /dev/fd0
step one does a low level format of the disk, basically cleaning it out
step two makes a linux filesystem on your floppy disk so that linux
knows how to actually read the information stored on your disk
