Note
To gain full advantage of your DDS drive you should use matching
cassettes. That is, use DDS-3 cassettes with the DDS-3 drive. This
allows the drive to store the maximum amount of data on the tape.
Interpreting the LED indicators
There are two LED (light-emitting diode) indicators on the
drive’s front panel. The Activity (green) and Attention (amber)
LEDs show the status of the drive.

indicates that the tape may be becoming unreliable, although

cylinder with the special cleaning cassette, then try the data
