Operating the DLT80 Tape Drive
44 DLT80 Tape Drive Reference Guide
Unloading a Cartridge
Press the Unload button or issue an eject command in the software application.
When the Operate Handle LED illuminates, lift the handle, remove the cartridge,
and lower the handle.
Selecting Drive Density
Drive density can be selected by using any of the following:
■
On a write from Beginning of Tape (BOT), change the cartridge density by:
— Pressing the Density Select button multiple times until the desired
Density LED flashes. Using the Density Select button always overrides a
host selection.
— Making a programmable host selection through the operating system.
(The Density LED is off, indicating automatic or host density selection.)
— Allowing the drive to default to the density of the cartridge that has been
loaded with the data compression ON (assuming the Density Select
button or the host selection was not used.) If a previous written cartridge
is inserted, the drive defaults to the previous density.
■
On a prerecorded cartridge, the drive uses the recorded density for all read
operations and appended write operations.
Caution: If reusing a prerecorded cartridge and writing from BOT, all
prerecorded data is lost. Density changes are also lost since they only occur
when writing from BOT.
