Hi,

I used the incorrect power adapter on my external Western Digital sata HDD and now it refuses to power up - it is acting as if a fuse has blown on the pcb - does anyone have experience of this? - I can't find anything that looks like it could be a fuse.

the pcb is a 2060-701590-000 REV A' with a Samsung chipset.

Alternatively, does anyone know where I can source a replacement PCB - I am aware that i need to swap the rom chip if I do this.

Thanks,

Dan

Are you sure, your pcb have external ROM chip?

You CANNOT simply swap the PCB on the model, there not an external ROM chip. It's programmed into the MCU (large chip in the centre of the PCB).

You need to either...

1. Repair the original PCB
2. Read the ROM from the bad PCB and program a new one, or..
3. Manufacture new ROM info from the SA information on the platters

2&3 require specialist tools like PC3000

I can do this, of course.

PM me if you're interested.

This case is unfortunately not DIY'able.

Can you upload a detailed photo of your PCB?

i don't think this PCB have ROM chip. i can handle this kind of case.

Yes unfortunately Western Digital have still not put effective TVS diodes on their PCBs. In the ROYL series drive (which you have) the ROM has been integrated to the large chip. There's no way you fix this yourself. Most annoyingly if you had a power surge on a Seagate or a Samsung it would just be a case of removing / replacing the TVS or fuses.
