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.
