Appendix B contains more information about the drive’s nominal capacities with compressed and uncompressed data However, the actual compression ratio (and consequent transfer rate) achievable in any particular case depend on the characteristics of the data being compressed, and may be higher or lower than these nominal figures.

Caution

Use only cassettes bearing the DDS-2 or DDS symbols. You cannot play audio DAT cassettes with these drives, even on multimedia systems. Data stored on DDS-2 cassettes cannot be read by some first-generation DDS drives.

Interpreting the LED indicators

There are two LED (light-emitting diode) indicators on the drive’s front panel. The Cassette-in-Place (green) and Drive Busy (amber) LEDs show the status of the drive:

Media warning

Amedia warning, when the Cassette-in-Place (green) LED flashes slowly, indicates that the tape may be becoming unreliable, although at this point no data has been lost. First, clean the tape head cylinder with the special cleaning cassette, then try the data cassette again. If the warning persists, copy the data onto a new cassette and discard the old one.

A media warning can also indicate that a pre-recorded audio DAT cassette has been inserted by mistake.
