How To Unlock an XBox Hard Drive With Hdat2

Recommended Posts

Here is how to unlock an Xbox hard drive with a program called Hdat2.

Software link: Please login or register to see this link.

Software is in attachment also. It is a Boot able iso. 


I've done a YouTube video showing how to unlock an Xbox hard disk with HDAT2 link here for the program Please login or register to see this link.

This is a WIP, there may be some errors :( I will try to update the videos and instructions over time ;) 

6th April edited YouTube video
9th May 2017 v60b4, new YouTube Video and updated instructions

Set up your PC with the Xbox hard disk as Master and the DVD drive as Slave.
Set the BIOS to boot from DVD/CD first.
When the program loads, be patient it takes a little while ;) 
Type "HDAT2" at the command prompt.
Select the hard disk by using the cursor keys and pressing enter.
Scroll down to "Security" press enter.
Scroll down to "Unlock device" press enter.
Then press "I" to change from User to Master.
Pressing "K" will scroll through a list of built in passwords, if you're lucky it'll be one in the list.
Xboxes are usually "XBOXSCENE" or "TEAMASSEMBLY" which are near the end of the built in password list.
Press "S" to set and then "Y" to confirm.
NOTE: You will only get 5 attempts, and then you will have to re-boot, and start again :( 
You can also enter a password manually by pressing "P"
Passwords can be entered in User mode, but you don't get the "K" option for the built in password list.

If you have "zeroed" your hard drive password then 30 HEX is DECIMAL 0.
Hopefully the video will show what I mean :)

HDAT2 also has other useful hard drive tools to repair bad sectors, erase etc...
Have a look at some of the other YouTube videos by other users ;)

      hey everyone, i replaced the cap in my 1.6 xbox and also finished the modchip (atleast i hope i did) and before i hooked up the dvd drive and hdd i tried to test it but all it does is come on and then go off and it does it twice and then on the last time it comes on and flashes red and green over and over, the mod chip has a orange light on and i am also attaching some pictures of my wire job let me know if i did something incorrectly

      EDIT: i looked for a different diagram and found i had done two wires wrong and now it is booting perfectly!

      So finally they are completely ready and for sale now
      I can offer 2 Versions off the cable:
      -The first offers stereo audio on the HDMI signal and 5.1/digital audio through the optical port.
      -And one second does offer 5.1/digital audio on the HDMI sigbnal and through the optical port.
      The price for the cable that only has stereo on the HDMI signal is 65€ (~87US$) +shipping cost 3,70€ (~4,30US$) and paypal fees.
      For the fully digital version that also offers 5.1 through the hdmi signal the price is 70€ +shipping cost 3,70€ (~4,30US$) and paypal fees.
      You can choose between black and white for the case color. I do also offer the Case with a cutout or as a completely closed case. You can easily illuminate the case with a couple 0603 leds and resistors. Solderpads for those are present!
      Got a couple HDMI cables ready in both the full 5.1 Version and the version that only offers stereo through the HDMI connector.
      If you have any questions just drop me a PM!
      To use the cable the Xbox needs to be set to NTSC region and then just plug it in and you connect your console to your hdmi TV!

      Hi all,
      My trusty old XBox has stopped powering up (no lights or drive activity, nothing). I have opened it up to check for leaking caps. It is a 1.0 or 1.1 version, so I checked the clock capacitor which had indeed leaked so I removed it and cleaned the pcb but still no joy. 
      Then I started testing the FoxLink PSU. The socket soldering looks ok and I found that at least the 1st coil has tension, but when measuring the pins on the mobo connector there is nothing (I also measured the Power OK and Power ON pins). I can’t see any visual damage on the PSU. Can I conclude that this PSU is dead or is this normal?
