That would take some time to figure out.
A good start would be if we could get more sniffed volume IDs and unencrypted Volume IDs from different discs so we can figure out the patterns in the keys, if there are any.
If you can guess the key down to 6 unknown bytes by jst knowing the manufacturer then it's will work, but the more unknown bytes the more impossible it gets.
Finding a pattern is the only way i think, and it will work as long as the discs follow these patterns.
As soon as they fall outside the box then you have to go sniff again.
