Although you can right-click on a floppy drive in Explorer or My Computer and select Format to format a floppy, there's a better way. Type Format a: /u at the MS-DOS prompt (substitute A: for whatever drive letter you wish). Using DOS instead of Windows to format floppies will yield better multitasking, meaning you'll be able to do other things while formatting floppies (strange how it multitasks DOS better than Windows). Furthermore, using the /u paramter specifies an unconditional format, meaning that it won't save unformat information, yielding a faster format and more free diskette space. To simply erase a floppy, type Format a: /u/q - this is much quicker than a full format, but will not ensure an error-free disk (see General Troubleshooting Techniques for more information). Remember, if Format reports any bad sectors, throw away that floppy immediately.
