Not a Match? Try our PCB Finder
  1. Locate the number imprinted onto your PCB board (circled in our picture), it should say OA90351.
  2. The number on the sticker on your circuit board should say OJ24297.
  3. Verify the number on the largest square chip on your board is: 88i9205.
  4. If the above are matching, then we can make a clone of your board. We will need you to mail the dead circuit board to us.
  5. To make the clone, we will need you to fill this form, then ship your DAMAGED PCB (circuit board) to us. We will copy the information from your PCB onto our PCB, then ship the working cloned PCB back to you. See detailed procedures here.

    If you prefer to do this yourself (transplant an 8 pin ROM chip), just let us know by emailing us or mention it in the comments during checkout.

    This process is ALWAYS necessary to ensure compatibility for this model: your board contains UNIQUE information about your hard drive. You can find a more detailed explanation here.

When to buy this item:

We recommend buying this item when you are sure it is the PCB. For example, if there was a power surge, or some components are obviously burnt, or the wrong power adapter was used to power up the drive. If the drive will not spin up at all, and wasn't dropped, chances of success with replacing the PCB are quite good.

There are no refunds with this purchase, so if you would like to describe the specific symptoms to us, please Contact us through our online form or at, we will try our best to reply within 12 hours.

Item Includes: circuit board, firmware transfer and installation instruction sheet
