There has been much discussion as to just what a megabyte is.  The prefix
mega, in the international CGS system means 1,000,000.  1 MHz is NOT 1,048,576
Hz.  The use of powers of 2 for this seems to have originated with IBM with
the introduction of the System 360 in 1966 (1967?).  Thus they referred to
2^20 as a megabyte (incorrectly).  

While we, within the computer industry, have long tended to accept 2^20 as our
deinition, we are alone in the scientific community on this issue.  The disk
manufacturers are right.
