locked and loaded

[Military slang for an M-16 rifle with magazine inserted and prepared for firing] Said of a removable disk volume properly prepared for use - that is, locked into the drive and with the heads loaded. Ironically, because their heads are "loaded" whenever the power is up, this description is never used of Winchester drives (which are named after a rifle).
