Test 07 -- Clear Fault Log
This test clears the fault log. Because Test 04 relies on
status history that would be cleared by Test 07, you might want
to run Test 04 before running Test 07. To execute Test 07,
perform the following steps:
1. Enter Test 07 and press EXEC switch. The LCD will
display FAULT LOG CLEAR.
2. Press EXEC switch to end the test and return to test
selection.
Test 08 -- Direct Or Continuous Seeks
This test performs direct or continuous seeks between cylinder
o
and the desired cylinder address. Operation stops if an
error occurs or if the EXEC switch is pressed. To execute Test
08, perform the following steps:
1. Enter Test 08 and press EXEC switch.
2. The display HEX CYL XXX asks you to supply a valid
destination address (between
o
and 662 inclusive on
736 MB, 1120 MB, 1153 MB, and 1230 MB drives; between O
and 564 on 850 MB drives). Enter three characters and
press SPACE switch. If you enter a destination address
identical to the current address (a zero-track seek),
Test 08 will not run and drive status code 61 will be
displayed.
3. The display DIR OR CONT?
DIC
asks you to select either
DIRect (D) or CONTinuous (C) seeks. Enter either C or D
to start test.
4. If D was entered and the direct seek was successful, the
LCD will display OK, CYL: XXX, where XXX is the
destination address previously entered. Press EXEC
switch to end the test and return to test selection.
5. If either D or C was entered and an error occurs, the LCD
will display SERVO ERROR: XX. Drive status codes (servo
errors) are defined in table 2-6 later in this section.
By running Test 05 or Test OE, you can clear the seek
error.
6. If C was entered, press EXEC switch to end the test and
return to test selection.
