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
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.

If the self test fails a second time, the Disk Drive assembly is
probably faulty.
