While a test is in progress, the program displays:
IN PROGRESS TSSDSS
where T indicates the test number, the first SS indicates the subtest
number, D indicates the drive (if tested), and the second SS indi-
cates the hardware status. This message may remain on the screen
for a moment. The following sections describe each subtest.
