There are many reasons why you want to have a safe copy of your drive key. In case a future upgrade does not go as planned, the current drive dies...you need to change your motherboard. All these should have brought you to keep a copy on your PC and another one sent to a hosted email (not a Pop3 kept on your pc !!!) or a printed copy. The key is specific to the motherboard which will not accept any drive not providing its associated key.
Recovering they key can be done from your original firmware (or any of
this specific drive hacked & functional firmware after that) obtained the first time you flash your drive. you can open that firmware with
FW toolbox 3.1B and copy (ctrl-c) the key information and paste it in a .txt file to print it.
You can also recover the key from a drive if it is functional (or at least that the access to the firmware is still possible using the usual command) and that the drive still has the key in it. Obviously if the key was overwritten with a wrong value before there is nothing to recover, or if the interface does not accept the command to dump the firmware to a file then you have lost the motherboard associated to that key. In some case, qualified person could desolder the chip and extract the key (if it is there

).
How to extract the key from a Samsung driveYou will need to use a USB memory stick (or floppy, or ntfs4dos) with the appropriate mtkflash on it. You can look at the
Textbook tutorial or at
myfranco thread to do this.
Follow this method to extract the firmware if you have a VIA Sata card or chipset:
- Connect you PC sata cable to the X360 Drive (some have to do this after step 2)
- start your x360 and pc to the dos prompt
- type mtkflash r /m /sata orig.bin
- list of port will appear (if your mtkflash is correct)
- power down your x360
- select the port on your PC, then count to 10 (you may want to try different count)
- power your x360 and the pc will read the firmware to the orig.bin file
For those with a ms25 you can skip step 5 and 7. Also, all chipset in the mtkflash compatibility list of the Textbook tutorial should also work (not just VIA).
You can now extract the key form the orig.bin file.
How to extract the key from a Hitachi drive (up to v59)You will need to use the slax v2.1 to place your drive in modeB. You can look at the
Textbook tutorial for this.
- place a copy of latest garyopa firmware in a directory under the root (i.e. C:\fw360)
- following the tutorial, activate the Hitachi in mode B and restart your PC to windows
- Go in command prompt (Start, Run you type cmd) and type cd \fw360
- type memdump (drive) 91004F0 1 10 key.bin where (drive) is the letter assigned to your x360 drive
- open key.bin with a hex editor to get the key
Note that you can also type
memdump (drive) 12200 8 8000 current.bin to get the entire current firmware, and open that file with FW toolbox to obtain the key.
How to extract the key from a Hitachi drive (v78 and probably ok for the version below)You will need to use the slax v2.1 to place your drive in modeB. You can look at the
Textbook tutorial for this.
- following the tutorial, activate the Hitachi in mode B and restart your PC to windows
- Open FW toolbox & Tools / Direct Drive Dump / RAW DUMP/ save it as current.bin
- open the firmware with same application to get the key
Note that some will recommend to do this process a few times to be sure the key is good.
In the event that a key cannot be obtained, it renders
the associated x360 motherboard useless (at least for now). Your options are to replace your motherboard (see
Xbox360 BST and obviously depending on your technical skills

), or acquire a new x360 (maybe just a Core and reuse your X360 harddrive).
