Disk manufacturers use a hybrid system, don't they, since the sectors are powers-of-two but they use decimal multipliers to inflate the size beyond that? So that a "marketing gigabyte" might actually be a megakibibyte.
What is really funny is the size is really 1440 KiB, which is not 1.44 MiB and is also not 1.44 million bytes. So in that case it was a mixture of the two units (they would have been better off calling them 1.47 MB, as the actual size was 1474560 bytes, or 1.406 MiB which is the actual size divided by 1048576).
