  1. And the reason why in the FGA it is said that it won't work is BECAUSE IT WON'T WORK! If you really want to attempt a PCB swap , you need to ALSO swap the actual chip that holds the specific drive configuration, something that is not really "easy" or at a "normal" DIY level, desoldering and re-soldering tiny surface mounted components (without damaging/overheating them) needs some tools, but mostly experience and familiarity with the procedure that - no offence implied - you seem like simply missing at the moment. jaclaz Hello jaclaz, I know that it is not that easy, if you can tell me another thing to do, I will try it, but I at the moment I do not know what else I can do. From your answer I understand that every single HD PCB has its unique ROM, thats why I won't be able to find another one wich matches mine. Could you tell my if I am right? From ebay I have found PCB sellers that tells the same of the need of swapping the ROM. Thank all of you for you help.
  2. Do you get a response from the hdd without the PCB connected? No, I didn't get any response from the hdd without the PCB connected, exactly the same as with the PCB is connected to the HD. That is the problem, therefore I don't know what I can do.
  3. Thank you for your anwser BlouBul, I completely removed the PCB from the HD so its completely isolated, and I also connected the GND + Tx + Rx, from the RS232 to the PCB. The reason of looking for a PCB replacement is that I cannot get any response from the PCB after sending CTRL+Z, so I cannot send any command to it, and I do not know how else I can do but looking for an identical PCB to replace mine and try to unbrick it if it is needed.
  4. Hello, this is my first post. I have BSY problem with my HD (BIOS does not recognise it), but when I try to connect the PC via RS232 TTL 3.3V adapter I can not get any anwer from the HD. the converter is working because if I sortcut the TX and RX I got the echo. when I connect the SATA Power to the HD it start spinning so it seems some parts of the PCB are working, and one led from my USB-RS232 adapter stars ligting. I also tried to change Tx Rx just in case, but it doesn't work. Could you help me? I am also looking for a PCB replacement for my HD: Seagate ST3500320AS Barracuda 7200.11 500GB SATA: Model: ST3500320AS Main Controller IC: ST V523C HDD Motor Combo IC: 100369972 Board Number: 100466725 P/N: 9BX154-303 Capacity: 500GB Firmware: SD15 Site Code: KRATSG Date Code: 09085
