Er, do hard drive manufacturers actually call gigaBYTES 1000 megaBYTES? I always thought they simply used bits (where 1000Mbit == 1Gbit), and just left out the identifier (bits vs bytes). I.e. I can say to an ISP I want to buy a meg of bandwidth, and I certainly do NOT mean 1 MegaByte (8mbit).
*shrug*
