Abstract
A system for cover screw float detection. The system includes a drive cradle coupled to a structure. The system also includes a moveable portion coupled to the structure. The system further includes a sensor coupled to said structure. The system additionally includes another sensor coupled to the moveable portion. Spatial separation between the another sensor and the sensor when the moveable portion is oriented in a screw float check position indicates presence of cover screw float in a disk drive disposed in the drive cradle.
Claims20
A system for cover screw float detection, said system comprising:
- a drive cradle coupled to a structure;
- a moveable portion coupled to said structure;
- a sensor coupled to said structure;
- and
- 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 cradle.
A system for disk drive cover screw float detection comprising:
- means for removable fixed retention of a disk drive, said means for removable fixed retention coupled to a structure;
- means for positioning a moveable portion into a screw float check position;
- and
- means for determining spatial separation of a sensor coupled with said structure and another sensor coupled with said moveable portion when said means for positioning is in said screw float check position.
A method for cover screw float detection comprising:
- receiving a disk drive in a drive cradle, said drive cradle coupled to a structure;
- orienting a moveable portion coupled with said structure to a screw float check position;
- engaging a drive bit with an associated cover screw of said hard drive, said drive bit of a plurality of drive bits, said plurality of drive bits coupled with said moveable portion;
- and
- determining the spatial separation between a sensor coupled with said structure and another sensor coupled with said moveable portion when said moveable portion is in said screw float check position.
