Since the 4GB download problem is as a result of a memory addressing 
problem, it should also be noted that the JEDEC memory standard defines 
giga (G) as 2^30 (1,073,741,824) and NOT as 10^9 (1,000,000,000).

Andy's exactly right, it's all down to the disk manufacturers wanting to 
advertise products as being 6.87% larger than their actual size.
