First of all I'd like to start out with this reply by saying that your hypothesis on what would have to be done to have a unique hdd password stored in the eeprom is not true. It would not be that difficult but good try at making it seem that way. Also, you had a great idea on how the hdds get locked. That may be close to correct but what you said about liveinfo is false. It will not unlock a locked hdd unless you have... what??? the eeprom contents because that's where the password is stored. It says nothing about serial numbers. Give that idea up. As a matter of fact here's a excerpt from teamassembly that gets you started in the direction you need to go.
News: UNLOCKING XBOX HDD - Source Code Released !!!!!
This is the FULL source code that will unlock any locked XBOX hdd!!!
(Provided the eeprom contains the correct HDDKEY that this drive was locked with of course..) here is a link to that page just so you can see.Don't you think that it would just read the serial number and calculate the password if that were possible??? or did UNDEAD from teamassembly just feel like making it difficult?? no that would defeat the purpose of his program.
(I've been reading about LiveInfo and it does detect the serial and model #'s from a hd locked with configmagic. It does not say anything about MS locked hds. They do not use the same method of calculating the password to lock with.)
Don't post again until you prove yourself. You are clearly wrong about what you say so I don't expect you'll be posting again.
