    As Dave said (and as my original post that vanished also said) we need to know the exact model and preferably serial number.

    The boards can change revisions during the life of the product, so the serial# helps in making sure you have one that is more likely the same.

    I'd suggest that you get onto ebay and try to find a similar (as close to identical) drive as you can and transplant the boards.

    What was the "wrong connection", because it must have been interesting to cause the problems you describe. I would suggest there is more wrong than you have identified and that is the basis for my recommendation above.

    Ah! I plugged an external IDE drive into an IDE socket that had accidentally been plugged into a firewire port internally (at the factory!)

    Killed the drive stone dead (and it smelt like it). Didn't try a board replacement though.

    If you do a board swap, I believe you'll also need to move the original Flash ROM to the new board, since the fimrware stores information in there that relates to the physical characteristics of the drive hardware.

    Edit: Or the data might be stored in a SerialFlash or EEPROM
