PCB ST3500412AS FW CC32 100535704 REV B PCB

need this urgent. Data required from the hard rive very important wedding photos !!

Are you really confident about the diagnosis that you need a PCB, and that you can do all the necessary steps to replace it? If so, then this should really be in the Hard Drive Market section of the forum...

If you want advice about that diagnosis, then you should supply the current symptoms, what tests you have done and their results, and what changed / happened between it working OK, and now not working (in whatever way you explain as the symptoms).

sorry im a new member. how do i move it to the hard drive section? its been tested and 100% pcb problem.

You (or I) can't move it - we could request the mods to do that, but perhaps easier (since this thread is so short) is to let this thread die here, and for you to repost from scratch in the Hard Drive Market section.

Good luck!

This supplier includes a mandatory firmware ransfer:

That said, sometimes there is an easy DIY fix. What is the problem with your board?
