Filename Rewind on Close Retension on Open Compression
Rewind on Close
Normally, the drive repositions the tape to BOT (Beginning of Tape) when the
device file is closed. Using the no rewind option is useful when creating and
reading tapes that contain multiple files.
Retension on Open
Retensioning consists of winding to EOT (End of Tape) and then rewinding to
BOT, in order to reduce errors. If this option is selected, the tape is positioned
at BOT as part of the open process.
Compression
Compression can be disabled or enabled.
