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.
This command does not apply to virtual media.
Erase Media command
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. Only options
supported by the selected device will be available.
