over powerd my board, help a numpty out

I think most people would recommend transferring the ROM ("BIOS chip"), but be aware that you must not damage this IC.

I don't recognise the "3260" IC, but sometimes these PCBs have a tri-axis accelerometer in that area. That said, your drive has a shock sensor and two rotational vibration sensors, so it would be unusual for it to have an additional accelerometer. But I could be wrong ...

In this PCB that location is unpopulated, which would be consistent with an optional accelerometer:

Also, the presence of all those passive components would suggest the IC has an an analogue section.

Thanks a lot!
