 the details in [2.About edition]),please substitute the description
 in this file with 'USB Hard Drive' from 'USB Flash Drive'.

 the following sentences.

#"USB Flash Security" makes the following two areas in USB Flash

   There is no room to save the other file in this small area.
   The area to save "release tool" is 4M Byte that is 1/2000 of
   capacity of a 8GB USB Flash Drive.
   It can be access without password, when the USB Flash Drive is
   inserted into PC. Data in this area is not protected, so we call
