If the header block containing the label can still be read from the
bad tape, there's an easy way to fix this.
dd if=/dev/tape of=scratch
change tape to the new one
dd if=scratch of=/dev/tape
Make sure you are using the rewinding versions of the tape descriptor
for the last write.
Now, if an amcheck can read that tape, it should be safe to put it
back in the rotation in the original tapes sequence.
You can even edit that scratch file with vim if you have to get a
label from a different tape because that ones really gone, but you
must not change the length of it. I've done it several times in
trying to keep a dds2 system running here, but like anyone being
beaten about the brow with a hammer, it feels so good when you stop.
