pose 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.

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.
