Forcing an Ejection
Attention: Force an ejection only as a last resort to recover a cartridge. Never use it
as a quick way of ejecting the cartridge. You can lose data if you force an eject.
The tape also might end up invalidly formatted, because EOD might not have been
written.
If you press the Eject button when the drive is busy, the drive first completes the
current task. Then it responds to the ejection request. This ensures that the task is
terminated in a controlled manner and that no data is lost.
There might be occasions when you need to unload a cartridge urgently, even at the
risk of losing data. To do this, you must force an ejection:
1. Press and hold the Eject button for at least 5 seconds. The LCD will display
"Force Eject."
2. The Autoloader waits 35 seconds to give the normal ejection process a chance
to occur.
3. When this period elapses, any tape in the drive is immediately unthreaded, and
the cartridge is ejected, regardless of what operation the drive was performing.
The cartridge then is returned to its slot in the magazine, and the drive is reset
as though power had been cycled. Because forced ejection might interrupt an
operation, it is possible that the drive will not write EOD before the cartridge is
ejected. This will cause a loss of data and an invalid formatting of the cartridge.
The data on such a cartridge should be readable up to the point where the
format violation occurred.
4. If no cartridge is loaded in the drive, the Autoloader waits 35 seconds, ejects the
magazine, and then resets as though power had been cycled.
Removal
If for any reason the Tape Autoloader needs to be removed from the system unit, be
sure to keep the 2-drop power cable and the 50 to 68 pin interposer with the tape
autoloader.
