If the drive was locked with config magic, and the master password is teamassembly, then try atapwd to unlock it with the master password. The xbox uses the user password, and that is derived from data on the eeprom as well as the model/serial of the HDD. I hope I'm wrong, but I don't see how liveinfo could work with out selecting an eeprom.bin. Also I assume that live info would only return the original user password that was originally on the drive. There is a very in depth article on the xbox-linux sourceforge site (More than one actually)
Anyways, hdlock/hdunlock/hddisabl use 20 byte key. Xbox/atapwd use 16 byte key
