    Hi all.

    What is this? Its a PCB for an hard drive. I'm hoping that it's the only thing damaged on the board and if I can replace it and get my HD up and running again.

    I had the drive running whilst some bit of metal was underneath it; so I'm assuming it might have shorted out as it doesn't turn on anymore. If I replaced the PCB with another one from the same model, the drive spins up but isn't recognised (I believe that this hard drive, the Samsung HD501LJ retains the firmware data that is usually on a ROM chip on the CPU).

    The TVS Diodies seem fine, with a high value one way and low value in the other. So I'm hoping just replacing this thing might be possible :)

    Thanks for any help.

    SMD Capacitor, guessing MLCC Ceramic Chip. You'd need to check the value from another hard drive.

    It might be easier to find a drive of same make/model/capacity that had a head crash and simply swap boards.

    What are the dimensions of the chip cap? No numbers, and size doesn't help much, as it could be 16V or 6V or thereabouts.
