Cylinder to GB space calculation

1 Cylinder = 55,996 * 15 = 839,940 bytes.

so 1000 cylinders = 839,940 * 1000

1 Megabyte = 1,048,576 (2 to the 20th power) bytes.

1000 cylinders = (839,940 * 1000 ) / 1,048,576 = 801.029 MB

1 terabyte = 2 to the 40th power or approximately a thousand billion bytes (that is, a thousand gigabytes).

1000 cylinders = (839,940 * 1000 ) / (1,048,576 * 1,048,576 ) = .000763 Terabytes
