So you are saying that my "12GB" drive is 12,000,000,000 bytes instead
of 12,884,901,888 bytes?

The drive in the notebook I am typing on now seems to be neither. If
I am doing arithmetic and reading hdparm output right, I think it is
12,072,517,632 bytes (smaller once formatted). Not a very round
decimal number.

My point was that big round decimal numbers are rare in computers, so
why do we suddenly need big round decimal units for talking about
computers?

Disk drives have inherently binary capacities, the only reason to
quote their capacities in decimal was to make them look bigger. I
don't see why we should have new units to make that easier. This is
particularly ironic when disk manufacturers are so good at making them
bigger at a pace that has seriously out-paced Moore's Law.
