Abstract:
A method of testing a floppy disk unit having a large storage capacity, said floppy disk unit being connected to a notebook computer, comprising the steps of:(1) sending Reset, Inquiry and Mode Sense commands to the floppy disk unit to check for any defects in a hardware circuit in the floppy disk unit based on whether said Reset, Inquiry and Mode Sense commands have been successfully executed;(2) testing a diskette inserted into the floppy disk unit for any error in read-out, write-in, and seek-by-track procedures and, if an error is found, displaying an error message and determining whether a service engineer should interrupt subsequent test procedures;(3) testing the floppy disk unit for any error in fast read-out, write-in and seek procedures for each of a plurality of different types of diskettes compatible with said floppy disk unit;(4) testing an ability of the floppy disk unit to execute a Format command on each type of diskette;(5) testing the notebook computer for any error in an automatic eject function for any diskette inserted into the floppy disk unit, wherein for a floppy diskette having tracks numbered sequentially from 0 to n, the step of testing the floppy disk unit for any error in read-out, write-in, and seek-by-track procedures, a head of the floppy disk unit is moved a maximal distance, and then is moved a progressively reduced distance until the head moves to a middle track of the diskette in a sequence commencing at Track 0, and then proceeding to Track n, Track 1, Track n-1, and so forth.
