The drive will complete the loading process, threading the tape and performing a load

sequence. The tape will be examined and the read/write circuits will be tested. This

procedure should take approximately 20 seconds. When the load sequence is complete

the green Tape LED will light to tell you the drive is ready.

Unloading a Cartridge

It is important to remove the cartridge before you turn off the unit.

Note:

You can not unload a cartridge when the tape drive is turned off.

1. Press the Unload button.

The drive will rewind the tape, open the door, and eject the cartridge.

2. Remove the cartridge carefully and place it in the protective plastic storage case

immediately.

Remember to label and date the cartridge for future reference. Do not mark on labels

with a graphite pencil. The graphite dust may contaminate the tape surface.

Forcing the Ejection of

a Cartridge

Only force ejection if there is no other way of retrieving a cartridge, or if you are not

prepared to wait for the normal eject procedure and urgently need to unload the

cartridge, even at the risk of losing data.

Caution:

You may lose data if you force an eject. The tape can also end up invalidly formatted,

because EOD (End of Data) may not have been written. Because of this, only force

ejection as a last resort to recover a cartridge.

There are two ways of forcing ejection.

•

Press the Unload button three times within a 5–minute period (or press the Unload

button twice in the 5 minutes following a SCSI UNLOAD command).

•

Hold the Unload button down for at least 5 seconds.

Following either of these actions, the drive waits until 35 seconds have passed from

the time of the first press, to give the normal eject procedure a chance to proceed. Once

this period has elapsed, the drive immediately unthreads the tape and ejects the

cartridge, regardless of what operation it was performing. The drive is then reset as

though the power has been switched off and then on again.

Note:

Forced ejection overrides and SCSI PREVENT MEDIA REMOVAL command which

may be in effect, and can abort any SCSI operations which may be in progress on the

drive.

Write-Protecting a

4mm Cartridge

You may want to write-protect the cartridge after removing it from your Echo. Write-

protection prevents accidentally erasing or overwriting data on the cartridge tape. The

write-protection switch is located at the front of the cartridge.

1. To write-protect a cartridge, use a fingernail or a non-magnetized small

screwdriver to slide the switch sideways toward the center of the cartridge.

When the hole on the edge of the cartridge is open, data cannot be written to the cartridge

and existing data cannot be changed or erased by the Echo.
