The simple fact is that GB has = been used for a binary number for decades, just as MB and KB, and the = moved from MB =3D 2^20 to MB =3D 1,000,000 was driven by Hard drive = manufacturers who wanted to market their 100MB drives as 104MB to fool = people into thinking the drives were larger than they were. 2^30 is a far more useful number when dealing with computers than = 1,000,000,000, which is why many MANY people still used 'GB' to mean = 2^30. But yes, you are technically correct, but that is the worst type of = correct. --=20 "Patience has its limits. Take it too far, and it's cowardice." - George Jackson
