Abstract:

A portable hard disk drive module enclosing all of the operative components of the disk drive is removably received by a receptacle in a microcomputer system. The disk drive module and the receptacle each have an electrical connector and these connectors are coupled when the module is in an operating position within the receptacle. The connectors comprise the sole interface between the operative components of the disk drive and the remainder of the computer system. The receptacle includes a transport mechanism for moving the module from a load position to the operating position and from the operating position to a module unload position. Accordingly, movement of the module between these positions in the receptacle is completely under machine control.

International Classification:

G11B 509

US Classification:

360 39

Abstract:

A disk drive system includes a disk controller system having separate head positioning and data transfer subsystems and supporting up to four disk drives, two of which may be removable, portable drive units and two of which may connect through a standard ST506 interface. The removable disk drives incorporate a read and write protected data cylinder for storing information such as the maintenance history of the drive, and a read only cylinder for storing a unique serial number as well as other write protected data. The system also features a high capacity, high speed sector buffer which allows continuous transfers of data to or from noninterleaved sectors and supports concurrent disk and system accesses.

Abstract:

Techniques for identity management, and more particularly, to techniques for performing universal identity management or governance over a wide variety of applications. In one aspect a computer-implement method is provided that includes receiving a request for a query of data or a CRUD operation on the data. The data is part of a target application hosted by an enterprise. The method further includes obtaining a schema of objects associated with the target application. The schema models a relationship between the objects, and the objects represent the data of the target application. The method further includes executing the query or CRUD operation on the objects based on the schema, executing the query or CRUD operation on the data based on the schema, and reporting results of the query or CRUD operation on the data.
