Epson 20020, 20040 Read, Verify Check, Run All Above Checks

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 .............		2 4 6 0
Press	ENTER	to return	to the menu

Press Enter when you have viewed the table.

If the results show BAD TRACKS on your disk, it is all right because those tracks will not be used. If, however, the results show any READ ERROR TRACKS, run the Destructive surface analysis described in Appendix D.

Run All Above Checks

To run all the tests on the menu in sequence, press 5 and then Enter. When you choose this option, all checks for the hard disk drives and controller are performed automatically in sequential order. Although you do not start each test, you must still supply the appropriate responses to progress from one test to the next.
