Sorry, I wasn't clear. It's x00's for the end of file markers, but
xff's for the end of media. Try something like this:
...
add_file("tape1_set1_file5.dat", 5120);
end_file();
add_file("tape1_set1_file6.dat", 5120);
end_file();
end_tape(); # Here's the difference.
sub end_file {
print "\x00\x00\x00\x00";
}
# New procedure.
sub end_tape {
print "\xff\xff\xff\xff";
}
...
It that doesn't work, try deleting the very last end_file(). It if
still doesn't work, then I'm out of ideas.
Best of luck,
Andru
