It seems a perfectly good question to me. The key part of the question is "how to identify the specific clusters on any disk which contain pieces of any particular given file" which is straightforward enough. RRUZ's answer nails it.
I also don't think it's too localized, because I've seen people wanting to do similar things before and there are legitimate reasons why you might need to. It's a rare requirement, but not unique.
