TEST NAME
Zilog HRM
WDCTST7 - a comprehensive, multisector, write-read-compare
test of the Winchester disk
PARAMETERS
disk drive to be tested (default=O)
number of test loops equals the number of iterations per lap
(default= 10)
DESCRIPTION
WDCTST7 exercises the Winchester Disk Controller by doing
large, variable-sized writes and reads to random disk
addresses. The test repeats n times, where n=#REPS in the
test line. Each test contains the following "loop" itera-
tions:
(1) Fill segment 1-3 with "AAAA"s.
(2) Fill a randomly chosen source buffer of random length
with random data.
(3) Write the source buffer into a random disk address.
(4) Read from the disk into a destination file.
(5) Compare the source and destination buffers.
(6) Fill the buffers with "AAAA"s.
(7) Check segments 1-3 for all "AAAA"s to verify that the
disk transfers did not corrupt locations outside the
buffers.
