The unformatted capacity of a DSDD 5.25" floppy is around 500k, so the 
overhead using 18-256 byte sectors or 9-512 byte sectors per track is 
around 39% overhead!  If you do the math between the two different 
versions of a gigabyte, 57 of one is 61.2 of the other so your overhead 
is negligible.  Of course that is because the 60 gigs *is* formatted 
capacity.
