Re: Reformatting 720 KB IBM diskettes

Simon,

    In answer to your first question, physically the disks are 
identical.  What differs is how the 'formatting' arranges file and 
directory information.  FAT takes a lot more room than some other 
formats.  (Most notably ProDOS and Amiga).  As to the second question, I 
have no idea. :)
