Claim:
A system for cover screw float detection, said system comprising: a disk drive retainer coupled with a top portion of a base structure, said base structure coupled with a housing structure, said disk drive retainer configured to receive a hard disk drive with a leak test valve; a moveable portion coupled to said top portion of said base structure, said movable portion configured to move vertically with respect to said base structure and with respect to said housing structure; a sensor for screw float check coupled to a support member coupled with said base structure; another sensor coupled to said moveable portion, wherein spatial separation between said another sensor and said sensor when said moveable portion is oriented in a screw float check position indicates presence of cover screw float in a disk drive disposed in said drive retainer; and a leak tester coupled with said moveable portion configured to couple with said leak test valve of said hard disk drive and configured to determine if said hard disk drive is sealed, wherein said leak tester is operable during said screw float check.
