A technique is described whereby a diskette and hardfile electronic drive simulator eliminates the need to use actual diskette and hard drives to test the adapters. The simulator also provides fault injection and parameter controls so as to stress the design of the circuitry used in the adapter. The simulator is a programmable device, controlled by a host processor, to emulate the functions of a diskette and hardware, as used in personal computers. It has the ability to read and reproduce the same data from two adjacent tracks that reside on contiguous cylinders after commands have been issued by the host to the adapter under test. It can also be programmed by the host to inject failures to the adapter during its functional test. Test results can be read by the host from dedicated registers in the simulator.
