As the program checks each track, it counts the cylinder
numbers (nnnn) down to zero. When the test is complete, the
program displays a report on the status of the disk, including a
table of unflagged tracks that produced write, read errors-such
as the following:

Count of tracks flagged bad n

= n n n n
No write, read error was detected.
No data was destroyed.
Press ENTER to return to the menu.

summary would show one track with a write, read error. The
report is followed by a table like this:
