Emax

hello, does anyone know how i can format a zip file on the pc for an emax II? My emax II can see my iomega zip drive and can read the size of it...but when i try to format it it says...Drive Not Formatted...any ideas? also worst case scenario...is it possible to format it using some software on the pc...as i would like to use emxp..and i think that only read and writes zip drives..doesnt format them

thanks a lot!
