Diskette Format This test checks the format of the floppy disk controller and drive. It does not format the diskette for any particular operating system. This test destroys all data on the diskette. Drive Speed Test This test verifies how fast the floppy drive rotates a diskette. Your internal, 1.44MB, 3 '/z-inch diskette drive should rotate the diskette at 300 rpm, allowing a tolerance of one percent. An external, 1.2MB, 5 '/+-inch diskette drive should rotate a 1.2MB diskette at 360 rpm and a 360KB diskette at 300 rpm. Again, allow one percent tolerance. To perform this test, insert a diskette into the drive you plan to test. Use a diskette you have formatted with the Diskette Format test. Random R/W Test This test checks the random seek capability of a floppy disk drive. It performs a random read/write operation on the diskette in the specified drive. To perform this test, insert a diskette into the drive you plan to test. Use a diskette you have formatted with the Diskette Format test. This test destroys all data on the diskette.
