To hard disk manufacurers, 1 megabyte = 10^6   bytes
To everyone else,          1 megabyte = 1024^2 bytes

Also, when talking about tranfer rates, a MB/s is often refers to 10^6
rather than 1024^2. Note that,

  1024^2/10^6 = 1.048576

Now, when talking about gigabytes, it is usually 1024^3... but
sometime it is 10^9. Or even better, sometimes people mix the powers
of two and ten, so that they call (10^3)(1024^2) a gig.
