4/10 APRICOT 340 OWNER’S HANDBOOK
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:
Green

Hardware error or high
humidity.
Media warning
A media 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.
