1 - WRITE, READ, COMPARE (ON TEST CYLINDER): Tests the hard disk
read and write operations.
2 - SEEK TEST: Sequentially moves the hard disk heads inward one
cylinder at a time until the last cylinder is reached. The heads then reset to
the first cylinder and a random seek test is performed.
3 - HEAD SELECT: Data is written to the test cylinder by each hard disk
head; the data is then read and checked for any errors.
4 - ERROR DETECTION AND CORRECTION: Tests the hard disk error
checking and correction circuits by reading data, altering the data, and
writing the data at the test cylinder. A comparison test detects any errors.
5 - RUN ALL TESTS: Runs tests 1, 2, 3, and 4; also reads track 0.
6 - READ VERIFY: A read operation is performed on the entire hard disk;
any tracks that cannot be read are reported with existing defects.
7 - FORMAT UTILITY: Selects the Format Selection menu.
9 - RETURN TO CONTROL PROGRAM: Returns to the System Checkout
menu or continues with the next device test.
