    Okay, Do you want to fix a hard drive board?

    The biggest reason I could think of to do that is to try and regain/recover to the information on the hard drive.

    For reliability reasons I would not recommend fixing and using as normal.

    There is likely something wrong - and with a hard drive it is likely to be mechanical.
    That bigger problem would be the reason that the IC fails.

    Assuming this is an old out of warranty hard drive - look for another used hard bdrive of the exact same type. Swap the whole board.

    That would normally be easier and probably cheaper than finding and replacing the IC.

    If you have the replacement IC, or you are just salvaging parts.

    To remove the old IC, paint on some liquid flux, heat carefully through desolder braid. Don't drag across the pins. Make sure you remove the braid while it is still hot so that it doesn't freeze to the board. That freeze would break pins and tear up traces. One ruins the IC - the other ruins the circuit board.

    Application of fresh solder to help melt the old solder is a trick that may help.

    Hot Air rework stations are helpful too, but probably you don't have one if you are asking for this type of help.
