Eject Media or Loader Magazine command
You can use this command to eject media from the selected device or eject media magazines from the
selected library. If this command is missing, either your device does not support this command or no
device is selected. Some device magazines will not be ejectable.
CAUTION:
When you eject virtual media, you cannot retrieve it. Be sure that the data contained on the
virtual media has been transferred to physical media or is no longer needed before you eject virtual media.
Rewind Media command
You can use this command to manually rewind tapes in the selected device. If this command is missing,
your device does not support this command.
NOTE:
This command does not apply to virtual media.
Retension Media command
The
Retension Media
command increases the tension of the current tape in the device by fast-forwarding
the tape to the end of the tape and then rewinding it to the beginning. This command can be useful in
some circumstances. Occasionally when a tape is repeatedly fast-forwarded and rewound for only short
distances, tension differences develop in the tape that cause the tape drive to falsely believe it has reached
the end or beginning of the tape. By increasing the tension on the tape, you can sometimes make an
otherwise unusable tape operational again.
NOTE:
If you need to retension tapes regularly to use them, consider servicing your tape drive or replacing
your tapes.
NOTE:
This command does not apply to virtual media.
Erase Media command
This command erases the media currently loaded in the selected device. It has the following options:
•
The
Quick
Erase
option erases the first block and then writes an
END OF DATA
marker to that
first block. The other blocks of the tape are not erased, but when that tape is read, Data Protector
Express treats it as if it were blank because it encounters the
END OF DATA
marker in the first
block.
•
The
Secure Erase
option erases every block on the tape. This operation can be very time
consuming, lasting several hours. However, it will physically erase every block on the tape. If
you want to destroy sensitive data, use this command.
Some devices support both options; some support only one of the two erase options. If an option is not
available, the selected device does not support that option.
Format Media command
You can use this command to format media currently loaded in the selected device.
When you format new media, Data Protector Express opens the
Format Media
dialog box. Use this
dialog box to name the media and select a media folder in which to store the media. Data Protector
Express will format the media currently loaded in the device you select. If you select a library, select the
storage slot that holds the media you want to use. This command also initializes virtual media.
