|i tried with 2 diferent xboxes, and 3 different eeproms on each box. the drive simply will not lock. all indicators in every program claim the drive to be lockable, but configmagic fails, avalaunch whines about wanting to unlock it once before to aquire a pass? even tho it says it is unlocked? X3 doesnt do anything except freeze for a few sec. after the command is issued, and xboxhdm says i dont even have a hard drive connected to my computer! i tried what the others suggested, i.e. putting a jumper on master/CS/both; nothing worked.
