If the cleaning cartridge is not ejected, it has probably expired. In this
case, press the
Eject button, discard the cleaning cartridge and repeat
the operation with a new cleaning cartridge.
The DAT 160 drives have a TapeAlert feature that notifies your
backup software application when the tape heads need to be cleaned
or when a cleaning cartridge needs replacement.
