• Option #2: Copy From: If you choose this option, Exabyte will prompt you for
the number of the file (obtained from the Directory option) to be copied to hard disk,
and prompt you to enter the destination path and name of the file to be created on
the hard drive. Once the number is entered, the utility rewinds the tape and copies
the file.
3. Rewind tape: The rewind option will position the tape at the beginning of the
tape. If the erase option is specified at this point, the entire tape will be erased.
4. Erase tape: The erase option will erase the tape from the current tape position
to the end. Before erasing the tape, the Exabyte program will ask you to confirm your
intention. The tape will be automatically rewound at the end of the erase pass.
To erase the entire tape
• Choose Rewind.
• Choose Erase.
To erase the tape after a specific file
1. Get a Directory.
2. Choose the Copy To option.
3. Enter the number of the last file you want to save.
4. Copy that file to the file name NULL (the file will appear to copy, but no hard disk
file will be created).
5. Choose Erase.
C.3 Using the SEG-Y Format on Exabyte Tape
Technically speaking, only genuine SEG-Y data can be written to SEG-Y tape media.
However, few people still use SEG-Y tape any more; most now use Exabyte tape. Isis
uses true SEG-Y data format on Exabyte tape. Except for the difference in the two tape
media types, our format is indeed true SEG-Y.
