This is a safety feature to make sure you don't shoot yourself in the foot.
If you are willing to throw away the changes in the journal that haven't been
committed to the normal locations yet, then you should be able to make some
changes to the journal to make it look like it is empty. You might even be able
to get away with just writing over the bad block. However, you really should
make an image of this partition before doing any writes to it. I don't know
what changes to make to the journal to make it appear empty.
