wait, so you mean you got the 360 drive recognized with a purely ntfs partition or the toshiba?  It was original Xbox drive with ntfs partition. Are you saying you formatted it as NTFS, swapped logic boards and then it got recognized !?!?! |

not formatted, only create ntfs or FAT32 partition.

Hi, I have desolderd the SDRAM_1 chip from logidboard_1 (HDD_1) and solder it into logicboard_2 (HDD_2) http://www.freepler.de/userdaten/38928917/bilder/xbox360/desolder_sdram.jpgso after swapping and change SN and hash, the HDD_2 (with logicboard_1 and SDRAM_2) was recognized. I know that was not necessary, but I wanted to go surely, and made this test. |

Did it also work 100% in the 360 ? So I mean drive from HDD 1 + board from HDD 2 + sdram from HDD 1 = 100% work on 360 ?

i doubt it too o.O
RAM needs voltage to remember data :s

Of course, but in theory it's possible to create a ramchip with a section with 'hardcoded' data, but then, this seems unlikely to me, since this would have to be a specially manufactured chip (containing some ROM) and this doesn't seem very likely, especially since it's a 'normal' RAM chip ... It all seems VERY weird to me  |

If you weren't the one that helped a lot with the ripping of the dvd FW, I'd say you're making an april 1st fool joke It all seems SO unlogical ... SDRAM holding the S/N on the chip Very weird .... And you didn't even swap bioses ? Naaah... I really have a hard time believing this |

I really have a hard time believing this I dont sure whether the SDRAM can hold this information, but I think it can be possible. I have swapped the SDRAMs. That is no april 1st fool joke!! http://www.freepler.de/userdaten/38928917/bilder/xbox360/01010003.jpgI would be very happy if somebody would confirm my work. |

Ok, I believe you But to make things clear: You have HDD 1 'mechanical part', with HDD2's data copied onto it, with HDD2's pcboard, with HDD1's SDRAM, right ? If so, then try to swap bioses (that 'U6 chip) now and see what it does. I'm guessing that it won't work in the 360 anymore, but will work in the PC, would be a VERY interesting experiment. This would mean that: the manufacturer married the mechanical part to the SDRAM chip and we can now find out if the firmware is used by the 360 for identifcation (in other words: we can now find out if the 360 has married the FW to the (hashed) data on the disk) |

While I first thought it was very unlogical, I think (am not 100% sure here though) that RAM chips always contain some kind of 'hardcoded info', like timing values. So why not a serial ? This would actually be a good way to marry something, since you can't flash it => if the marriage was in the FW, it wouldn't be much of a strong good marriage, hehe, since it would be easy to reflash the info. Anyway, now the VERY interesting test will be to find out what happens if the bioses are swapped ... |

sure, but I'd still like to see what it looks like for the xbox360 (being full capacity)

My first thought was about 93C66 containing unique info, it's very strange that sdram have all the stuff instead...well, tomorrow i'll believe |

After swapping the bioses (93C66B) there were no changes!! datasheet for (93C66B) http://ww1.microchip.com/downloads/en/devicedoc/21795c.pdf------------------------------------------------------------------------------------------------------- HDD_1 (SN_1 + hash_1) + board_1 + SDRAM_1 + bios_1 = all original HDD_1 + (SN_1 + hash_1) + board_2 + SDRAM_2 + bios_2 = no join and recognition in xbox360 and PC HDD_1 + (SN_2 + hash_2) + board_2 + SDRAM_2 + bios_2 = also no join and recognition in xbox360 and PC HDD_1 + (SN_1 + hash_1) + board_2 + SDRAM_1 + bios_1 = works fine in xbox360 and PC HDD_1 + (SN_2 + hash_2) + board_2 + SDRAM_1 + bios_1 = works fine in PC but no recognition in xbox360 HDD_1 + (SN_1 + hash_1) + board_2 + SDRAM_1 + bios_2 = works fine too in xbox360 and PC
HDD_1 + (SN_2 + hash_2) + board_2 + SDRAM_1 + bios_2 = works fine too in PC but no recognition in xbox360HDD_ = 'mechanical part' board_ = 'logicboard' bios_ = '93C66B bios' SN_ = 'serial number' hash_ = 'hash data' |

So, this would mean that the SDRAM is the key in both processes: linking of the HW to the mechanical part AND the linking done by the 360 ... *EDIT* it's also possible that the 360 is not using some kind of serial info at all, but some info that is identical for both FW's, like the HDD's 'type' nr for example. Furthermore, it seems weird to me that that U6 EEPROM is only 4 kb, since this is no where enough to store the FW in my opinion ... So, maybe this is the most crazy theory ever, hehe, but would it be even possible that that SDRAM chip contains the FW ? Naah... it's even too weird to write it here, but ... All this is so weird and doesn't make much sense to me ... SDRAM that contains the linking info and a 4K chip to store the FW |

TMF: have you tried formatting it on the x360 instead on the PC?
please show a pic :X
