You can use dd to move the tape past EOF.  You must use the no-rewind
tape device for this to work (the tape device names that end with a "n").
Try "dd if=/dev/rmt1hn of=/dev/null" to move the tape forward one "file"
or EOF flag at a time.  If you have the mt command, you can use it to
do the same thing.
