How to use

HddHacker supports two flashing modes, Auto and Manual. Typing HddHackr at a DOS prompt
will start auto mode. In auto mode all hard drives will be detected automatically.
In manual mode you can enter all the parameters used for flashing by hand.

The following help screen is displayed if you start HddHacker with a wrong number of

                D: Dump sector 16-22 from XBOX360 HDD to file
                F: Flash Western Digital firmware
                R: Restore Western Digital firmware
             PORT: Port to send command to e.g. 09F0
        DRIVE POS: A0 for Master, B0 for Slave
      SECTOR FILE: Sector dump file e.g. HDDSS.BIN
     RESTORE FILE: Firmware restore file e.g. UNDO.BIN

Example for dump, flash and restore:

Explanation of the Parameters

- this will set the mode of operation, it is recommended to first try to dump the XBOX360
  hard drive data, if the dump will fail, it is highly unlikely that a flash or restore
  will succeed on the Western Digital drive

- the port to which the Hard Drive is connected, a port number should always be entered
  in hexadecimal and have 4 hex digits, valid ports are: 01F0, 09F0, .....
- this option can be used if your PCI adapter card or on board SATA ports are
  not identified by the auto mode

- on SATA ports this value is always A0, cause you can only connect a master drive to
  a SATA port, so for SATA you will always type A0 here

- name of the sector 16-22 dump file better known as HDDSS.BIN

- name of the firmware restore file e.g. UNDO.BIN

Using HddHacker in manual mode

* Dumping the HDDSS.BIN file *
Boot to MS-DOS from a writeable medium (like a floppy or UBS Stick).
Connect an *original* Xbox360 HDD to your SATA controller. Make sure it is the only
SATA device that is connected. Now run 'HDDHACKR D [PORT] A0 HDDSS.BIN' and it will create
the file 'HDDSS.BIN' and save it to the path you've started HddHacker from.

* Flashing your Western Digital *
Now turn off your PC and connect the Western Digital hard drive. Boot to MS-DOS again.
Type 'HDDHACKR F [PORT] A0 HDDSS.BIN UNDO.BIN' from the same path you have saved the HDDSS.BIN
file to. This will create an 'UNDO.BIN' file that you need if you want to undo the hack
and flash your firmware back to the original state.

* Restoring your WD to original state *
If you don't want to use your modded WD HDD in your XBOX360 anymore and you want to
flash it back to its original size/state, then you can now do so. Boot to MS-DOS and 
run 'HDDHACKR R [PORT] A0 UNDO.BIN'. This will use the UNDO.BIN file you created before to 
restore the drive to its original state.


Q. Will this tool allow me to connect a 500GB drive to my x360 ?
A. No. The information on sector 16 is signed and can't be changed. You can 
only use the size where you have a valid signature for. In otherwords, if a 
bigger HDD comes out, then you can use that signature.

Q. With which HDD's does this work ?
A. As of version 1.00, it now works with all sizes and versions of the
WesternDigital Scorpio Series. 

Q. Do I need the same size WD HDD as the size on sector 16 states ?
A. No. You can use bigger HDD's, but you can't use more than the size stated 
in sector 16. You can NOT use smaller HDD's than the size on sector 16 states.
For example, you can use a 40GB HDD with a sector 16 from a 20GB HDD, but 
not the other way around of course.

Q. Can I use the HDD in my PC again ?
A. Of course. The tool comes with an 'restore' option, that will restore the 
original size. For example, you use a 40GB WD HDD, you used HDDSS.BIN from
a valid xbox360 20GB HDD, so the tool will transform your 40GB HDD into a 20GB HDD.
However, you can restore it to 40GB anytime you want with the restore option.

Q. I lost my UNDO.BIN file, can I use it from another drive ?
A. There's no guarantee this will work. It might kill your drive.
Using a UNDO.BIN from a different model (e.g. LAT/RST) will kill your drive for sure.

Q. I have a XBOX360 Core/Arcade version and want to use this hack to buy a cheap HDD. 
But how do i connect it ?
A. If you don't have a Premium/Elite, you can make the HDD internal. One great tutorial
that will show you how to do this:

Q. The tool doesn't detect my HDD !
A. First, make sure you are running it from real MS-DOS, not from a DOS box under windows. 
If the HddHacker does not autodetect your SATA controller then let us know about it.

Q. The HddHacker says the UNDO.BIN file already exists.
A. If you previously made an UNDO.BIN file, then you should keep that one. There's no 
need to create another one. Keep in mind that the UNDO.BIN represents the current state
of the drive.

Q. Could you do this for my Seagate, Maxtor, Samsung or whatever drive too ?
A. Yes, but I don't have plans to do so. It is a lot of work to convert this tool
for usage with other brands and don't think it is worth the trouble.

Q. Where can I donate ? 
A. Nowhere. Just enjoy!
