XboX HD Maker V1.6.1

Changes :

- An small update to 1.6. No new functionality, but the changes
  mentioned below have been requested frequently be users so I
  figure a .1 update was in order.

- The HDD detection on Primary Master was improved so that
  the xboxhd tool works for locked HDD's also (previously
  the tool aborted, telling the user to unlock the HDD).
  Now menu options 1-5 are simply disabled if the drive is locked
  but the user can still generate the HDD password if the eeprom
  was included on the CD and make a DOS floppy with locking/unlocking
  tools.

- When making the DOS floppy with locking tools from the xboxhd
  menu option 7), the HDD password will be written to the floppy,
  and on reboot the user will have two new commands :
  *  lockhd, will prompt you to choose a drive and will lock the 
     HDD with the password written to the floppy by xboxhd
  *   unlockhd, will both unlock the HDD and disable locking with 
      the password written on the floppy
  So the locking unlocking should be automatic and hopefully prevent
  users from producing paperweights.
  If the locking was not succesful doing it this way, you should always
  be able to unlock the drive again with the password stored on the 
  floppy in : input\hdpass.txt
