Read, verify check
This test reads and verifies data from all tracks of the disk, checking each
cylinder and using both heads.
Select option 4 from the menu to start this test.
The program displays the number of each cylinder it finds. For example,
with a 20MB hard disk, the first message you see is:
Current cylinder is
614
The cylinder number counts down to 0.
At the end of the test, you see a table of the results of the test. For
example, for a 20MB hard disk with no bad tracks, you see:
BAD TRACKS ..................... 0
READ ERROR TRACKS .............. 0
GOOD
TRACKS . . . . . . . . . . . . . . . . . . . . 2460

not start each test, you must still supply the appropriate responses to progress
from one test to the next. The first prompt you see is:
The data on the highest physical cylinder may be
destroyed by this check.
Enter Y to start this check.
