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?
These are typically not user serviceable and should only be opened in a clean room. That HDD is probably toast now. The read head is that bar sticking out over the platter. It moves across the platter, reading the magnetized data.
Just to add that "clean room" is ~~a huge understatement~~ the actual, correct, technical term, when it comes to HDD internals (see below)
I mean it in the industrial sense. An actual clean room.
oops, my bad. Im not smart.
I've corrected my comment.
I think it was a good call out. You recognized that just being inside of a clean bedroom or something isn't adequate, and it led to my clarification which will probably be useful for a lot of people.
