Aargh.  How many times do we have to repeat: that is NOT "industry-style", 
it's ISO standard.  The "real" factor would be 1024 if the size was given as 
500GiB.  It's only confusing because people insist on saying "500 gb 
declared = 476 gb real".

In any case, its never been true of disks.  The numbers manufacturers report 
are "unformatted", and no disk ever sold has actually been able to store 
that many bytes once formatted into cylinders, tracks and sectors.
