In this figure, the switch is set to Write a value position by default, the
hexadecimal value 0x00 is entered into the field.
This is what the window control elements means: You may enter any
hexadecimal value into the field under the Write a value switch to write it to a
hard disk during any pass (during the first pass in this case).
By setting the switch to Write a random value position, you first will select write a
random value to disk, and specify the length of random value in bytes in the
spinner field below.
The U.S. standard provides the writing of random values to each byte of each
disk sector during the first pass, so set the switch to Write a random value position
and enter 1 into field.
