The Quantum BigFoot TS is an extremely old hard drive that does not even fit the xBox and its chassis. While it can be formatted to FATX, this will never work without a modification chip "hard mod" that makes it so that the hard drive need not be locked.
While it attempts to lock, you receive an error that it was not successful.
