Solving Media Warning Problems
A
media
warning fault usually indicates
that
either
the
tape
head is dirty,
or
the
tape
cassette
is
nearing
the
end
of
its useful life.
To correct a media warning problem,
1.
Eject
the
suspect cassette from
the
DDS drive.
2.
Clean
the
tape
head using a cleaning cassette.
3. Insert
the
suspect cassette
and
repeat
the
operation
that
was being performed when
the
media
warning occurred.
If
the
media warning does
not
recur,
the
tape
head was simply dirty.
The
cassette can
continue
to
be
used; however, you should remind
the
customer
to
clean
the
tape
head
regularly.
If cleaning
the
tape
head did
not
the
fix
the
media warning fault,
it
may indicate a problem
with
the
cassette itself. In this case, continue with
the
following steps:
1.
Copy
the
data
from
the
suspect cassette onto a
hard
disk drive.
2.
Eject
the
suspect cassette
and
install a new cassette.
3.
Copy
the
data
from
the
hard
disk drive
to
the
new cassette.
4.
Retry
the
operation
that
was being performed when
the
media warning occurred.
In
the
unlikely event
that
the
problem still occurs,
it
may
indicate a problem with
the
DDS
drive hardware, in which case
the
entire drive must be replaced.
