There is a high chance your pcb doesn't have a U12. Post a clear picture of the component side of the pcb and someone will pinpoint it for you. On the other hand, what makes you sure your hdd has a pcb problem? |

If your board looks like this one ... http://pcb-hdd.com/images/WD3200AAKS-75 ... %20PCB.jpg ... then U12 is vacant, which means that the firmware is inside the Marvell 88i6745-TFJ1 MCU. This particular MCU has a fault that sometimes mimics a head or media problem. |

A small part of the boot firmware is in flash memory on the PCB, but the major part of the firmware is in the System Area on the platters. That said, there is not enough information to determine whether your problem is a PCB fault, or whether there is an internal fault. As for copying the flash contents from one PCB to another, some PCB suppliers include such a service for $20. In fact one board supplier who is also a member of this forum offers such a service at no extra cost. To retrieve firmware modules and ROM data from the HDD, see the MHDD scripts here: http://yura.projektas.lt/files/wd/mhdd/index.html Your drive is a ROYL, and you will need MHDD ver 4.5. |
