Troubleshooting the Analyzer
To troubleshoot disk drive failures
3 Check the Disk Drive assembly.

following keys:
[

[
Return]
[

[
clear test log]
[
Return]
[
special test modes]
[

[
restore]
[
random seek]
[

Any number between 1 and 2771
[
read]
[
read/write]
b If any of the self tests failed, insert a new formatted disk and
repeat the previous step.
If the self-test message reads ‘’Bad or unformatted media,’’ the
flexible disk is most likely bad or unformatted. The analyzer can
use either LIF (Logical Interchange Format) or a DOS formatted
disk.
c If the disk drive self tests still fail, the Disk Drive assembly is
probably faulty.
d Press the
[read/write all] key.
The read/write self test can take up to 40 minutes to complete if
there are no failures.
e If the self-test message reads ‘’Bad or unformatted media,’’ change
flexible disk and repeat the read/write all self-test.
f If the self test fails a second time, the Disk Drive assembly is
probably faulty.
If the self tests pass, the Disk Drive assembly and flexible disk are
functioning correctly.
