If a request has a Range header, read only the desired portion from the data volume, and return the segment with appropriate HTTP status (206) and headers (e.g., Content-Length: 10001, Content-Range: 1234-11234/100000).

Skip hash verification (this would be impossible without reading the whole block). If a client needs to verify content hashes, it can either retrieve the whole block ahead of time and compute the checksums of each segment, or retrieve ranges in order and compute the hash piecewise.
