yeah, i suppose you need to transfer adaptives at the least. would it be hard to post a pic about the pcb? |

Did you dump the ROMs, or did you just solder them? In any case, could you dump all 4 ROMs? I have written a tool that can parse the contents. |

My software extracts all the firmware modules from a HGST ROM. https://www.hddoracle.com/viewtopic.php?p=23963#p23963 |

My tools run in a CMD window. They extract the components from your HGST ROM dumps. You need to dump the ROMs, then my tool will analyse your .BIN files. |

Sir i could finally open your amazing tool with CMD . i dragged the ROMs one by one on CMD and i the HEX editor opened automatically^^ should i save this two ROMs and write it on the CHIPs? just in case this is my two rooms. https://drive.google.com/drive/folders/ ... sp=sharing thank you for your patience |

No, it doesn't. And in your situation, it is not ROM issue. Same problem you get if connect only PCB. User area access is different story. Do you hear long double recalibration of you hard drive or it became ready within a second? |

Doesn't this imply that something was written to the donor ROM by the patient drive? I assume that the donor is still spinning. |

Here is another thread where a donor drive was damaged after the OP messed about with ROMs: https://forum.hddguru.com/viewtopic.php?f=1&t=44071 |
