    Capacity:
    Capacity is the amount of data that the drive can store, after
    formatting. Most disc drive companies, including Seagate, calculate disc
    capacity based on the assumption that 1 megabyte = 1000 kilobytes and 1
    gigabyte=1000 megabytes.

Disks have a natural measurement of capacity based on an integral number
of 512byte blocks. So kilobytes (1024) makes sense for them.

The only marketing wizardry is to use the smaller of:

        1 megabyte = 1000 kilobytes

instead of:

        1 megabyte = 1024 kilobytes

There are valid arguements for both interpretations.
