LED Warning Conditions – DDS–DC Drive
High Humidity – If the LEDs display the high humidity signal, the humidity is too
high and the drive does not perform any operations until the humidity drops.
Self–Test (Failure) – If the LEDs display the self–test (failure) signal, a fault was
diagnosed during the self tests. Note the pattern of the pulses and contact your local
service representative.
Media Wear (Caution) – Hewlett–Packard DDS drives continually monitor the
number of errors they have to correct when reading and writing to a tape to
determine tape wear and tape head cleanliness. If excessive tape wear or dirty tape
heads are suspected, the drive warns you by displaying the Media Wear (Caution)
signal on the LED indicators.
If the LED indicators on your DDS–format drive display the Media Wear (Caution)
condition, follow this procedure:
1. Check the system console for any tape error messages. A hard error during a read
or write operation may have occurred.
2. Clean the heads with a cleaning cassette (HP92283K) as described in the
"Cleaning the Tape Heads" section, later in this chapter.
