Data Protection

Write-Protection of the Data Cartridge While Inside the Drive

The Write-Protectswitch on the data cartridge can be moved while the cartridge is loaded into the drive. The drive will turn on the Write Protected LED immediately. However, if the drive is writing to the tape, write protect does not take effect until the write operation is completed.

If you move the Write-Protectswitch from the write-protected position (on the left) to the write-enabled position (to the right), the tape becomes

Swrite-enabled after several seconds.

If you move the Write-Protectswitch from the write-enabled position (on the right) to the write-protected position (to the left), the tape becomes write-protected after several seconds.

Write-Protection of the Data Cartridge Outside of the Drive

Move the Write-Protectswitch to the left to write-protect the tape. The Write Protect LED (orange) is ON and data cannot be written to, or erased from the tape.

Move the Write-Protectswitch to the right to make the tape write-enabled. Data can now be written to, or erased from the tape, assuming it is not already software write-protected.

Tape in Use

Whenever the Tape in Use LED (yellow) is ON steady, the tape is ready to use. When the tape is being read, written, or rewound, the Tape in Use LED blinks.

Use the following table to determine what is happening during cartridge use:

	(Right Indicator Panel)
LED	State	Meaning
Tape in Use	ON steady	A cartridge is loaded, but the tape is not moving. This
		can mean no application is communicating with the
		controller, or that the application is communicating but is
		not delivering commands for tape motion.
	Blinks irregularly	A read or write is in progress.
	Blinks regularly	Tape is loading, unloading, or rewinding.
Operate Handle	ON and beeper sounds	Tape is unloaded into the cartridge and the cartridge can
		now be removed, or if the drive is unloaded, a cartridge
		can now be inserted.
All LEDs	Blinking	An error has occurred during operation.
