Device Group
Device Group describes the device group that is presently highlighted in the Device
Groups list on the main menu screen. It also provides reasoning for using some
tests.
Device
Device is the educational section of the online Help. It describes the function
and purpose of the highlighted device in the Device Groups area. For example,
the following information appears when you select Device for Diskette in the
Device Groups list:
Diskette drive A:
The diskette disk drive device reads and writes data to and from diskettes. Diskettes
are flexible recording media, sometimes contained in hard shells. Diskette recording
capacities are small and access times are slow relative to hard disk drives, but they
provide a convenient means of storing and transferring data.
Test
Test provides a thorough explanation of the subtest highlighted for a selected device
group. For example, the following description is provided for the Diskette Drive Seek
Test:
Diskette drive A: - Diskette Drive Seek Test
This test verifies the drive's ability to position its read/write heads. The test operates
in two passes: first, seeking from the beginning to ending cylinders inclusively, and
second, seeking alternately from the beginning to ending cylinders with convergence
towards the middle.
