Ah... So this is the thing that bothers me - if each component file in the chd had its pre-compressed sha1 stored, I could probably legitimately identify the source files on at least some occasions by looking for those hashes in other dats . It frustrates me that only the combined sha1 of the cue and bin files are stored. That makes tracing the origin source files substantially more time consuming (got to extract and sha1 scan every chd).
Am I making sense here? Wouldn't this be a reasonable feature request for chdman?
