it is more likely that you used the "rewind on close" tape
devices for the dumps instead of the "no rewind on close"
tape devices. the result would be that the tape would
be rewound after every dump and every dump over-writing the
ones that came before it.
whether or not you can get the tape drive to read past
the end-of-tape marker depends on the mechanism. software
tools alone may not help. you will also need to know how
large the disk2 dump is, if it is large then there may
not be much of disk1 left on that tape.
