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?
Not necessarily. It varies by manufacturer, and some manufacturers use both methods for the various HD's they make. Both work just fine, and both have their strengths and weaknesses.
Okay got it.
