i have an idea...could you try copying the data from the original xbox360 hdd to the 100gb toshiba, then put the original xbox360 hdd logic board on the 100gb toshiba?

No, this will not work, the logicboards are different!!

Great work !! Respect ! So it indeed seems that the FW on the board contains a specific serial number that is hashed on disc ... Maybe you could try to copy the 'hashed' info, change the boards and see if it then works ? (make sure to back up the info before of course, hehe  I don't know if you have hardware to dump the flashes on the boards, but this would also be VERY VERY interesting to compare ... About that samsung board: that controller, is that a 'mediatech' ? Can't find anything on that chip. Then we have a 64M bit SDRAM chip and that '5AAN8ETAG4 TLS2502' will be the flash memory I assume ? Also can't find any info on it ... |

On the hitachi board, U6 S93C668 seems to be a 93C66 Microwire serial eprom, also the pin layout seems to be classical microwire connection. Anyway marriage between electronic/mechanic is present also in some standard PC HD as far i've seen Damn, i'm still without any 360 box  |

Its been a while since I read through the ATAPI spec but I seem to recall that there was a provision for the drive to set aside a region on the disk for non-accessible storage (for saving things like private hashes and passwords). It may, therefore, not be (reasonably) possible to transfer everything you need from one drive to another. If you are serious about it I would look through the security portions of the ATAPI spec. |

Hmm... didn't know that. How is this marriage done ? *EDIT* I didn't read the first post right, so the HD didn't work on the PC either ... Then this marriage explains why  As the serial nr is also on disk, maybe all there is to the disk/board marriage is a simple compare: serial on disc against serial in FW ? And the hashed info is only checked by the 360, to verify the serial ? To Team Modfreakz: maybe an interesting experiment would be to backup the data from 1 hd and make a 1:1 clone of the HD onto the other HD, switch boards and check again ? |

And what happened to you 360 ? I believe your drive died, right ? But don't you have the HD ? |

So, I made a backup of the HD1 and restored it into HD2. Than I swapped the logicboards - same thing, no join in Xbox - Error E68 And also not working in the PC I guess ? Maybe there's some data on disc we dont' have acess to, like Speed8ump notes ... Hmm... |

So, then it indeed seems there's some data on disc that you can't access 'normally'. Still, it seems a bit weird ... why would a manufacturer marry the pcb-board to the drive ? And if the marriage key is in the FW, this would mean that they could not easily do a complete FW update ... Anyway, next step would be I guess for someone to make some ATAPI logs (a little birdie is working on this already) and a dump of the FW's ... |

I have found maybe something interesting. After connecting only logicboard to XBOX I get also Error E68, it comes up shortly before dashboard screen. But hard disk with not original logicboard there it happened immediately after turning the Xbox on. Another interessting thing, I used PartitionMagic 8 and create 100% NTFS partiotion. Than connected the drive to xbox and it was recognized.  |

Console seems to do model/revision/firmware check early on. This check passes because model/revision is correct. But then it want to access the HDD just before dashboard screen, which fails. But hard disk with not original logicboard there it happened immediately after turning the Xbox on.
This is the first check early on, makes sense. HDD is rejected because model/revision is not correct. |

That's a good question. I'm guessing to prevent exactly the type of tampering you are trying It would seem to me that tying the drive media to the control circuitry would make unauthorized access of the drive media harder. Security through obscurity. And if the marriage key is in the FW, this would mean that they could not easily do a complete FW update ...
Unless the firmware knows how to update itself and preserve or update the stored information, which I'm sure it does. What would be difficult would be recovering data from the drive if the control circuitry dies. For that reason I would assume that there isn't anything random in the encryption process...it is pure obscurity. |

Reading HDDGURU website, seems like some HD have a serial port for debuggin and a "safe mode" state initiated by closing some jumpers. Hexediting some hitachi firmwares, it seems that some ascii text about serial interface degugging is present.
Have you a scan of the other side of the hitachi board?
