Hi My Seagate Barracuda 7200.11 hard drive (HP12 firmware) is locked in BSY state. I read a lot of information about how to unlock Seagate drives (with a Seagate firmware), but it seems that the procedure is different when the firwmare is HP12. I would appreciate if you could give me the right procedure for the HP12 firmware. Thanks in advance Patrick |

Maybe this? viewtopic.php?t=19422&p=178807#p178807 If you have some electronics skill, and if you can build a simple circuit, then I may be able to help you. It should cost you about $5 in parts. Alternatively, I can help adapt something from eBay. |

I have bought all the necessary material. All I need is information for unlocking a Seagate Barracuda 7200.11 hard disk with HP12 firmware. Patrick |

According to that other thread, and assuming that the same method applies in your case, you need to inject an interference signal into the read channel. For that you need a signal generator. Your TTL RS232 adapter is something else entirely. I'm not a data recovery professional, so I don't have personal experience with this problem, but no professional is going to tell you their secret, no matter how trivial. I propose to use a 555 timer, a capacitively coupled probe, and a resistive voltage divider. Some private feedback would suggest that this procedure does indeed work, at least for the ES.2 models. |

No I didn't try. I want to know the exact procedure before starting. I don't want to damage my hard disk. Patrick |

Hi I've just connected the drive to the terminal, and the message is : LED:000000CC FAddr:002493D1 Patrick |

Do you get an "F3>" prompt if you issue "Ctrl-Z" ? |

I didn't try, since when the disk is in BSY state, the terminal is locked. |

Why not insulating the head contacts in the first place ? |

Why is it important to power off/on the disk between the N1 and m0,2,2,0,0,0,0,22 commands ? Some people say it isn't necessary. |

Hi I finally unlocked my hard drive and updated the firmware. I used the standard procedure, but with the following modifications : - I used the / and F,,22 commands after the U command - after the N1 and / commands, powering off and on the drive locked the terminal, so I restarted the whole procedure from the beginning, without disconnecting the drive after the N1 and / commands I then backed up my data and installed the latest firmware (HP26). I don't know if it is the simplest procedure or if it works for other people, but it worked for me. |

I didn't use properly the word "unlock"  What i wanted to mean was if you are stuck in terminal because commands as translator don't work you need to do CONGEN on HP 7200.11 drives.
