Actually, the problem isn't the hard drive manufacturers.  The problem 
is with the first people to call 2^10 bytes = 1024 bytes a "kilobyte," 
because--believe it or not--kilo meant 1000 long before the kilobyte.  
Ask any of those people who live in any of those countries with the 
funny base-10 measuring system (think kilogram, kilometer (or is that 
kilometre ;), ... ).

Just because the first word you heard to describe 1024 bytes was a 
kilobyte doesn't mean it's right.  I guess the International 
Electrotechnical Commision, in trying to decide on a way to 
unambiguously describe both 2^30 bytes and 10^9 bytes, decided that 
"gibibyte" and "gigabyte" sounded better than "gigabyte" and "salesman's 
gigabyte."  And, since the IEC coined these terms, other standards 
bodies--including the IEEE and NIST--have adopted them.
