So I opened this harddisk because it was not spinning and it kept on making a click sound. This is an old harddisk , so I understand that the technology has changed. But I can't seem to find the read head parking area which most tutorials show or explain. So my question is, which is the resting position of this read head? Also is there a type or version of this sort of hdd?
You might be able to identify the problem. It's likely something dumb like a popped solder joint on it one of the chips. You can probably pop the whole board in the oven and reflow it. If it's only 10 years old then it would fall under ROHS and would be lead free, if you decide to go that route.
