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?
If it's just clikcing it means that the voice coil (magnet and copper part on the other end of the read head) isn't getting energized. The fix would probably be to repair or replace the circuit board on the outside, not anything internal.
It's a 10 year old HD. I doubt the circuit board can be replaced now. But the data wasn't important so it's kinda fine, but if I could fix it easily that would be nice as well.
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.
